Kill Weeds Without Killing Your Good Grass

March 25, 2012

“Help! The weeds are winning!” You dig them… they grow back. You treat them… but you killed your good grass too. You put down a crabgrass preventer, but you still got dandelions now. You ask, “So… what’s the secret to killing weeds?

You see, dandelions and other weeds like thistles have long taproots that can go down a foot or more. If you don’t get all of the root, it will simply send up a new weed to replace the one you thought you dug up. So digging can be hit or miss.

The commercial comes on TV for Roundup and you think I’ll use that to kill the weeds in my lawn. The fact is that Roundup kills plants after you spray their leaves, including your good grass. Roundup is great for driveways and other areas where you want to kill everything, just not for spot treating weeds in your lawn. (One of the great things about Roundup is you can plant shrubs, trees, flowers, vegetables, lawns within days after you spray. Just check the label for timing.)
So unless you want to kill the grass that is growing around your weeds, do not use the Roundup in your lawn.

Other folks think you need to put the weed & feed down before the weeds appear… wrong again. Unlike the crabgrass preventer that goes down before you see the crabgrass, most weeds are perennials and can’t be prevented.

So here’s the secret: The weed & feed, like Scotts Turf Builder with Plus 2 goes down AFTER you see the weeds in your lawn. That’s because the weed control in the product enters the weeds through the leaves and is transported to all parts of the plant including the roots. Then within a few days, the weeds will begin to curl up and wither. Gradually over a period of about 3 or 4 weeks, they’ll fade away, roots and all, so they can’t grow back. When you apply the Turf Builder with Plus 2 it is also very important to apply to moist foliage so the particles will stick to the weed leaves to get absorbed. If rain is expected within 24 hours, wait until another day. I find it best to apply early in the morning when the lawn is covered with dew.

Also keep this in mind: getting rid of the weeds is only half the battle. Your lawn will be a stronger competitor with new weeds if you feed your lawn regularly (about 4 times a year) and mow your grass a little bit taller.

One more thing, if you only have a few weeds, you may not need the weed & feed on your entire lawn. You can spot treat weeds in a Ky Bluegrass, Fescue, Perennial Ryegrass, Zoysia, Buffalograss, or Bermudagrass lawn with Ortho Weed-B-Gon MAX plus Crabgrass Killer  (note: may cause temporary discoloration on Bermuda) and then keep your grass healthy with a feeding of Scotts Turf Builder. And before I forget: If you have St. Augustinegrass, use Scotts Bonus S as your weed & feed instead of Plus 2.

If you have questions about the weeds in your lawn, you can call one of our lawn experts or email us. Just click here for our Help Center to see how.

    I have brand new house and a brand new lawn. It was all graded and ready to be seeded. I used a broadcast spreader to spread grass seed and starter fertilizer. We have had very dry weather and I am trying to water as much as I can but the grass is barely coming up if at all. Meanwhile weeds are growing like crazy and swallowing up the lawn. What should I do? Any help would be very very appreciated.

    • Hi Jason
      Let me know where you are located and what seed blend you planted. This will help me give you some suggestions.

        Thanks. Here you go:

        20% Kentucky Bluegrass (Sod Quality)
        15% Newport Kentucky Bluegrass
        15% Ken Blue Kentucky Bluegrass
        25% Creeping Red Fescue
        15% Quebec Perennial Ryegrass
        10% Fiesta III Perennial Ryegrass

  3. Hi Jason
    The Perennial Ryegrass should begin germinating in 7 to 10 days after planting. The other grasses take at least 14 days to germinate. Spring seedings take longer to grow than fall seedings. Sometimes the weeds can look overwelming, however if you begin mowing when growth is tall enough to cut so the weeds do not shade the young grass seedlings, and then once you have mowed your new grass seedlings 4 times, a weed control can be applied as long as the weather is not too hot. Watering is the most critical step to good germination. Here is a link to a blog posting on grass seed faliure that outlines all the things that I have seen contribute to seed germination problems:

    Great article. I am a new homeowner and a lawn/grass noob. I purchased Scott’s weed & feed AND turf-builder at Home Depot because I was able to get 25% when buying both at the same time.

    My question is this. I have a moderate weed problem in the lawn. However, the brown spots and “dead zones” are worse. I used the turf-builder first. How long should I wait before using the weed & feed. Is there a chance I can “burn the grass up” if I use it too soon after the turf-builder?

    Thanks in advance!

    • Hi Christian
      It is a good idea to allow about 6 weeks or so between feedings. If you let me know where you are located I can give you recommendations for products and timing for the coming year.

    Is scotts turf builder + 2 harmful to pets?

    • Hi Melissa
      Yes. As a pet owner myself, I follow the directions on the package: The directions say to keep your pets off the lawn while you are spreading. You apply this product to a moist lawn, like first thing in the morning when there is dew on the grass. Then don’t water and stay off the lawn for 24 hours (including pets) so the particles can stay in contact with the weed leaves so the weeds will be killed. After 24 hours it is ok to water, then when the lawn is dry your pets, and anyone else, can go on the lawn. I have heard folks say they treat the front lawn one weekend and let the dogs go out back, then the next weekend they treat the back lawn and let the dogs go out front. Good luck with your lawn.

    My yard is in pretty good shape I’m just not sure what to put on it crab grass preventer weed n feed or turf builder. I’m in southern nj

    • Tom permalink

      I have already bought the weed n feed just don’t know if it is ok to put down

    • Hi Tom
      Still time to get the crabgrass preventer down in your area, however you need to do it right away. Since your lawn is in pretty good shape, you may not have much crabgrass. And since you already bought your weed and feed, you can put that down instead. This will give you the feeding your lawn needs now and kill any weeds that are there. Apply to moist foliage when rain is not expected for 24 hours. If you get some stray crabgrass later this year, you can spray with Ortho Weed B Gon MAX plus Crabgrass Killer.

    I live in Columbus Ohio and have an extreme case of dandeli ons in my front and back yard. both are pretty much solid yellow right now.

    its a moderate size yard maybe 1500 total square feet I’m not sure what grass we have if any since it is almost entirely dandelions right now. I swear every day they multiply 3 fold.

    I was looking at going with Scott’s weed and feed to help but wasn’t sure if that was the right way to go and when I should apply it and how to get control of my lawn.

    I just mowed today because they were getting so out of hand and we had so many bees and with a two year old who loves the outdoors I had to do something.

    help me please! =)

    • Hi Geoffrey
      You may be surprised how much grass you have when you take away the dandelions and feed. Put down Scotts Turf Builder Weed & Feed on moist foliage (first thing in the morning is good when your lawn when there is heavy dew on the ground. Pick a day when rain is not expected for 24 hours. Stay off the lawn that day. Then after 24 hours it is ok to water and to go on the lawn after the lawn has dried.

      • Geoffrey Smith permalink

        Any specifics on what temperature I should wait for to put the weed and feed down? For instance its not suppose to rain until Wednesday so I was looking at doing it tomorrow morning but it won’t get above 40 degrees until 9am 50 degrees around 11am and mid 60s after 2pm

      • Hi Geoffrey The mid day temps should be at least in the 60′s. As long as it is not frosty in the morning, you should be ok. I should say though you will likely get a little better results if the temps were a bit warmer. The weeds need to be actively growing to absorb the weed killer through their leaves.

      • Geoffrey Smith permalink

        if there isn’t any dew in the morning should I gently water my lawn before applying? And then when and how often should I be watering my lawn after I apply the weed and feed

      • Hi Geoffrey Yes, if your lawn is dry, water first. Put the Weed & Feed down and then hold off any watering for at least 24 hours. You can then water after that.

    Hi Ashton,
    We made the mistake of putting down Scotts Weed & Feed two days ago (after cutting the lawn and wetting it down). It is due to rain tomorrow. Our law has two parts: 50% of fully “green” with grass and weeds and 50% has SOME grass & weeds but is mostly plain dirt.
    Now, our major mistake we have learned is that we did not seed first. We are totally embarassed by large dirt areas of the lawn and I’m sure we’re doon to have brown and bare spots from all the weeds also.

    Our question is: what is your experience with when we can put down the grass seed? (The product states 4 weeks). Would there be any difference if we were to bring in several inches of new topsoil? Would sod make any difference?

    Thanks in advance for your help!

    • Hi Courtney
      My experience has been you need 4 weeks to wait and seed after putting down our weed & feed. If you had seeded first, you would have had to wait until you had mowed your new grass 4 times before putting down the weed & feed, so don’t beat yourself up too much. The first part of your lawn that was 50/50 should improve with the grass getting fed. In the mostly dirt area you could try to seed the worst areas by breaking up the soil to a 4 inch depth and mixing in an inch or so of Scotts Lawn Soil and seeding with Scotts EZ Seed. If you are in an area with hot, dry summers you are probably better off waiting to do a major reseed job in late summer/early fall.

      • Courtney Eyster permalink

        Thanks Ashton! We live in Maryland, so hot but humid summers. You mentioned possibly breaking up the soil for 4 inches or so. Can you explain the purpose behind this? Is it to dilute the weed and feed? Or something else?
        Can you help me better understand what exactly Scott’s weed and feed is? I’ve been ready lots of “stuff” about these products in general and I can’t quite understand. A local nursery explained something about a vapor gas that is produced that hangs around and prevents the germination. …trying the get the scoop and I figured you’re the best bet!
        Last, if we DO break up the soil, bring in new addition al soil and seed, what is the worst that will happen? For example, I figure it may not grow, but then what? Could it start growing in 4+ weeks after the weed and feed has dissipated or will we need to reseed or could we blow our chance and have to wait until fall?
        Just trying to weigh all our options.
        Thanks for your time to answer all my questions.

      • Hi Courtney There are two types of lawn food products that have weed controls. The first one is a lawn food plus crabgrass preventer (like Turf Builder with Halts). It is kind of late to put that one down in your area as crabgrass has probably already started to grow. This one works like the person in the nursery stated. You can not seed for 4 months (not weeks) after putting down this product. The second weed control plus lawn food is typically called a Weed & Feed (like Turf Builder Weed & Feed). This product is for weeds like dandelions and clover and works by getting absorbed into the weed leaves to kill the plant (that is why you put it on moist foliage). You can not seed for 4 weeks after putting this product down. The idea behind breaking up the soil and mixing Scotts Lawn Soil prior to seeding is to dilute the weed control. The weed control also dilutes during the 4 week period, especially when there is lots of rainfall. Based on where you live, fall is a better time to seed than right now as the grass seed would have a better chance to grow a strong root system before the hot, humid weather. Our best grass seed blend for your area is Turf Builder Heat-Tolerant Blue Grass Seed. Hope this extra info helps.

    We live in Concord NC and are in a home where the sod was already down. I believe it is Fescue but it is hard to tell exactly. There are a lot of weeds coming through now and we have just been mowing weekly to keep them down. Will they eventually stop coming up in the summer or will they keep growing through? What do you recommend?

    • Hi Melissa
      If you have not fed your lawn yet this spring, I suggest Scotts Turf Builder Weed & Feed. Apply to moist foliage when rain is not expected for 24 hours so the granules will stick on weed leaves. You can then water after 24 hours. If you have fed, you can use a different product for the weeds: Ortho Weed B Gon MAX plus Crabgrass Killer.

  10. Geoffrey Smith permalink

    Hi again – I have the weed and feed now and have been waiting for a day where there isn’t suppose to be rain for at least 24 hours – but my problem is now the dandelions and grass is wayyy long.

    Can I mow first before applying the weed and feed – and if I do how long should I wait after mowing to apply it?

    Or should I just weed and feed tonight while all the weeds are huge – and mow sometime tomorrow night?

    Thanks!

    • Hi Geoffrey
      Mow your lawn first. You can apply the next day. It is better to apply in the morning when the lawn is moist from dew if your schedule will allow. If not apply when you can to moist foliage when rain is not expected for 24 hours.

  11. Geoffrey Smith permalink

    OK sounds great =) Thanks so much for all the help … here’s to a better weed free lawn!

    I’ll be sure to do some before and after pictures too.

  12. Joyce permalink

    DO I NEED TO CUT THE GRASS BEFORE APPLYING THE WEED AND FEED?

    • No, unless the grass is tall enough to keep your spreader from working properly. You do not want to mow for at least 24 hours after you put the product down because you want the granules to stay on the weed leaves to be absorbed into the plant to kill it. If a lot of your weeds are low to the ground, mow first, then apply the next day to moist foliage.

  13. Scott permalink

    I put down starter fertilizer and wondering how long I should wait before putting down weed and feed? Got weeds popping up. Northern IL

    • Hi Scott
      Assume you put down grass seed with your starter fertilizer application. If so, you can put down weed and feed after your new grass has been mowed 4 times. If you did not seed, you can follow your Starter feeding 4 to 6 weeks with weed and feed.

  14. Jeff Oliver permalink

    my whole yard was full of flowered yellow dandelions and by the time I went to put my weed and feed down they all turned into the white seedlings. What should I do? mow them down (they are atrocious looking) and then apply weed and feed? Our should I wait until they have flowered yellow again before applying the weed and feed? I was also wondering your opinion on concentrated hook up to the house multi weed killer that ” isn’t suppose to harm your lawn”

    • Hi Jeff
      You should mow your grass and treat your dandelions. Your options: If you have already fed your lawn this spring, you can spray with the hose-end Ortho Weed B Gon MAX plus Crabgrass Killer. This product kills 200 kinds of weeds including dandelions without harming your grass. If you have not fed, you can put down Scotts Turf Builder Weed & Feed. This product kills about 50 kinds of weeds including dandelions. The second part of your strategy to get rid of dandelions once and for all is to mark your calendar to treat again next Sept or Oct with either a weed & feed or spray (if you are feeding your lawn with a separate trip across the lawn). The reason I am suggesting this second treatment next fall is the baby dandelions will be in your lawn from all the seeds blowing around this spring. They will be easy to kill before they do their seed spreading thing again next spring.

      • Jeff Oliver permalink

        So after I mow there aren’t going to be any dandelion flowers left just maybe some stems, will the weed and feed be as effective our does it need to go on when they are yellow flowers?

      • Hi Jeff The key is to get the granules on the broad dandelion leaves that are low to the ground. So, apply to moist foliage when rain is not expected for 24 hours so the granules will stick to the leaves. The weed killer will be absorbed and translocate thru the plant to kill it root and all. Do not worry about whether the dandelions are flowering or not.

      • Jeff Oliver permalink

        if I have a flower bed with some annuals in it and its very close to my lawn do I just need to be careful with the weed and feed? or can it hurt the flowers?

      • Hi Jeff You should not spread the weed & feed into your flower bed.

  15. Sara permalink

    We moved into our house a few months ago in Memphis and our whole front yard is nothing but weeds and mostly shade. My question is do we have to wait till all of the weeds are gone (which I’m assuming will look like we have dirt for a lawn) before we start trying to grow grass. We have talked about seeding but I hate the idea of having a dirt lawn for months while waiting on the seed.

    • Hi Sara
      You live in an area where lots of folks grow Bermudagrass, however this grass does not do well in shade. So the alternative is to plant a blend of Fescues as long as the area gets at least 3 to 4 hours of filtered sun each day. Less than that and the lawn will always be thin. I am a big fan of our Heat-Tolerant Blue blend. In your area, in would be better to wait to plant this in early September. The decision you have now would be to kill the weeds now leaving what grass you have, or to mow this summer and then tackle your lawn this fall. Killing the weeds now will get you a jump on converting your lawn later.

  16. Randy Le permalink

    Hi Ashton, we’ve moved to a new home with a big front yard and small back yard. Both need to have NEW grass. I’ve read many of your advice here and have a couple questiions:
    1. My yards are in pretty bad shape with lots of weeds (of different kinds). The soil seems fine as flowers are growing healthy. For new grass, will “Scotts Turf Builder with Plus 2″ do the job? Or should I also spread more grass seeds?
    2. My back yard has lots of tall weeds around the house foundation, will ”
    Scotts® Liquid Turf Builder with Plus 2 Weed Control” be enough?
    3. I just mowed my yard, and the weather here (Silver Spring, Maryland) is still very cool, when is the best time to spread “Scotts Turf Builder with Plus 2″ and “Scotts® Liquid Turf Builder with Plus 2 Weed Control”?

    Thanks in advance.

    • Hi Randy Le
      In Silver Spring it would be best to hold off on putting grass seed down until around Sept 1 as it is getting late this spring to get enough root growth to make it through the typical summer there in the DC area. The Scotts Heat-Tolerant Blue grass seed mix is good for your area. You can take care of weeds now. If you have not fed, the Turf Builder Weed & Feed (was Plus 2) can be used, apply to moist foliage when rain is not expected for 24 hours. If you have fed in the last month or so, you could spray your weeds with Ortho Weed B Gon MAX plus Crabgrass Killer. This product controls more kinds of weeds than Turf Builder Weed & Feed. Neither product should be put down in areas where you are growing flowers (you mentioned the foundation of the house where you may have some flowers planted).

    Hellos Ashton,

    I live in Suwanee, Georgia, I’m a first time homeowner who just moved in to a property with the lawn in pretty bad shape.

    I have a 6200 sqft bermuda grass lawn which would make a nice lab for weed killer products lab. I pretty much have all types of weeds, moss, empty spots, you name it :(

    I tested Ortho Weeds B Gon MAX in the front of the house and most of the dandelions and clovers are curling down -it was applied about 10 days ago.
    I see other weeds were not affected in those areas.

    Now I got a bag of Turf Builder Weed & Feed but I’m not sure if it would be safe to put it down on the areas where I treated with Ortho. Should I just use fertilizer on those areas?

    My plan is aerate and use the Weed & Feed and then reseed if I successfully get rid of the weeds.

    Questions:

    1) It is safe to use weed & feed in areas previously treated with Ortho? If not, what would be better a) Use just fertilizer and continue with Ortho. b) Split and use Weed & Feed for the untreated area plus fertilizer only for the treated one?

    2) For the weeds not affected by Ortho, is there a better/broader spectrum herbicide?

    3) I’m not sure which type of Bermuda I have, is there any type of Bermuda that works better in my area?

    Thanks in advance!
    Rod

    • Hi Rod
      You will find that if you feed your Bermudagrass about 4 times a year beginning when you see about half or more of it turning green in spring and continuing at 6 to 8 week intervals into fall you will help it get thicker with fewer bare spots. Scotts Turf Builder or Scotts GreenMAX are great lawn foods for your area. The Ortho Weed B Gon MAX is the best option for the weeds. (I assume you used the Ortho Weed B Gon MAX plus Crabgrass Killer. There is an Ortho Weed B Gon MAX, however the one with Crabgrass Killer in the name is the one I would use.) You get a broader spectrum of weeds with that product than you will get with the Scotts Turf Builder Weed & Feed. Give the weeds you sprayed a chance to die which can take up to 3 weeks or so. You can spray the survivors on at that time if needed. If you have any left, it would be good to get an ID on them to decide what to use. If your lawn is sunny, the Bermudagrass will get nice and thick with the regular feeding.

    Hi Ashton,

    I read all your comments above and felt you’d be the right person to answer my question. To begin with, I live up north in Toronto, CA. I have a moderate size front yard where I worked rather hard to build the lawn, and glad to say the new grass is coming up strong and healthy and green. That said, I do have weed, mostly dandelions, some Canada thistle, crabgrass and plantain (I ID’d the weeds from this site – http://www.bhg.com/gardening/pests/insects-diseases-weeds/types-of-weeds/#page=1). I’ve researched a lot on the internet for various types of weed killers and have some names, but I want some expert advise before I buy them. Here are my questions:

    1. What would you suggest i use to eradicate all of the above mentioned weeds. What frequency should I be following over the course of a year?
    2. The spots where I overseeded and covered bare spots is growing a bright green, but the older grass is a lighter green in colour, anything I can do to make the whole lawn the same colour?
    3. I have a flower bed in the front yard which a stone edge. To avoid having to run the mower close to the stone border, I’ve created a 6inch border of mulch around it to kill the grass under it and have more space to run the mower by. It looks pretty except that I still do have grass growing from beneath it in many spots. Here’s my main question – Can I apply Round Up to just that portion of mulched area to kill the grass? Will it adversely affect the lawn/flower bed surrounding it? If not, how else can I kill the grass under the mulch?
    4. My back yard is tiled and has some flower beds. i have creeping charlie growing in their. Can I use the same thing you’ll suggest for point 1 on these pesky weeds too?

    That’s all that I can think of right now. I apologise in advance for the length of my query but I’m trying really hard to get that WOW! lawn. :)

    Thank you very much in advance for your help!

    Rashmi

    • Hi Rashmi
      Ortho has a weed control product called Killex that will work on most of your weeds without harming your good grass. Please note though that new grass should be mowed 4 times before spraying weeds in that area.
      New grass is a brighter green than older grass. This will even out in time.
      You can use Roundup in that area, just be careful not to spray your flowers or your lawn.
      Creeping Charlie is harder to control. The Killex will work, however you will find that spraying in fall is the best time of year. So, plan to treat again if necessary.

      • Rashmi Mukherjee permalink

        That was super fast! Thanks a ton Ashton. I have already mowed my lawn twice, so I can wait another 2 mows to apply the product you’ve mentioned. Where can I buy Killex? i will be travelling to Chicago end of this month, so if it’s not available in Canada, I can pick it up during my trip.

      • Hi Rashmi Ortho Killex is only sold in Canada. In the U.S. we sell Ortho Weed B Gon MAX plus Crabgrass Killer at all major retailers. Have a great weekend.

    Hi, I treated my lawn with weed and feed yesterday and thoroughly washed out my watering can. I found out today that my girfriendhas watered my plants with the watering can!!! I have sprayed them heavily with a hose, but am worried my plants will die! Will they be ok? I did wash the can out thoroughly…

    • Hi Tim
      Sounds like you did all the right things to avoid injury. Some plants are more sensitive than others, such as tomatoes. You will know in a few days if your plants have no damage. If you see some damage, it may be temporary and you will see new growth that is healthy. I will keep my fingers crossed for you. (Be kind to your girlfriend as she probably feels very bad about the whole incident.)

        Thanks Ashton. They still seem full of bloom this morning, though the only casualty seems to be my chives in my herb planter! My girlfriend and I laughed about the whole thing to be honest. At the end of the day, no one was hurt! Great site btw. Some really good tips.

    How are you doing. I recently redid my front grass with Virgo tall fescue seed and now I’m getting weeds and grab grass. I pull them out all the time but feel like I’m making patches everywhere by pulling them. I also bought weed&feed but now I have yellow patches everywhere. Please help.

    • Hi Manny
      Sometimes spring seeded cool season grasses, like tall fescue, do not have enough time to get established before hot summer weather, especially in years when the weather turns hot/humid sooner than normal in late spring/early summer. In this case a lawn fungus can get going before the lawn is strong causing circular brown patches. Fall seeded cool-season grasses have more of a chance to develop deep roots. Weeds like crabgrass are also more of a problem when seeding in spring. It is also recommended to hold off on putting down a weed and feed until the new grass has been mowed 4 times. New grass can be more sensitive to a weed & feed if the temps are starting to get into the upper 80′s and 90′s. Mow your grass at one of the taller settings and you may need to seed thin areas this fall.

  22. Chris permalink

    I live in Southeastern Louisiana with Florida St.Augustine grass. I have two small issues. One being an area in the front lawn of my house where a strip of the grass is lush and green at the bottom ( towards the street) and fades to dull and dry looking towards the top (or towards the house). The other pieces of the front lawn that are not connected are lush with a minor weed issue. What do you think is causing that dry dull look and what can I do? I do feed my lawn on a 4 time a year Scott’s program. Also I have a dog that loves to go to the bathroom in the backyard how can I prevent my grass from turning yellow from his urine? And how can I fix the current yellowing?

    Thank you!!!

    • Hi Chris
      Several thoughts: The way you describe your grass near your house suggests it may dry out faster in that area than the area near the street. Maybe the soil is different, or there is a slight slope away from the house or there is other vegetation near the house grabbing the available water. My other suggestion is to make sure you are protecting against insects like chinch bugs. If you are putting down a whole lawn granule treatment to protect against fire ants, you are getting chinch bug protection. If not, consider using Ortho Bug B Gon MAX several times a year. This also kills fleas and ticks in your grass. If you put it down at the heavy rate you will also get fire ants. Regarding the weeds, your spring and fall feedings can be Scotts Bonus S Weed & Feed. If this does not take care of all the weeds, you can spray with Ortho Weed B Gon for Southern Lawns.

      You can spray your weeds with Ortho KillEx. This will not hurt your good grass. Be sure to feed your lawn 3 or 4 times a year to help your grass grow into the areas were the weed grew and to get your lawn thicker so new weeds have a more difficult time getting started.

    Hello Ashton,

    I take care of lawns. I have a client that I fertilized about 4 months ago and now we noticed that his lawn now has more weeds than ever. I just put down some 20-0-10 lesco product to see if it helps. I guess my question is…Do you think that fertilizing the lawn increased the weeds more and if so can I can I fix this issue. I value him as a client and want him to be happy.
    Btw: I live in South Florida and the type of grass he has Is a St Augustine grass.

    • Hi Malachi Benedict
      Thanks for telling me where you are located as this really helps. There are many “winter weeds” that germinate in South Florida during Fall and thrive in the Florida winter growing conditions before fading away in summer. These weeds will come back every year from seed. Feeding can stimulate their growth. I am not familiar with the product you recently applied, but if it has a weed preventer in it, you will not see any control of existing weeds. If it is a weed and feed for St. Augustine, you may see some control. You would not want to put down Scotts Bonus S Weed & Feed for St. Augustine since you just fed. If you decide to spray the weeds, be sure to use a weed control that is ok for St. Augustinegrass. You may have a variety of St. Augustinegrass called Floratam that may be more sensitive to some weed controls, so read the label. Check out Ortho Weed B Gon for Southern Lawns to see if the weeds listed are the ones you are trying to control. Good luck.

    Hi Ashton,
    I’m a new home owner and the previous owner didn’t take care of the lawn at all. I have a couple of bare spots and weeds are taking over. I put pre-emergent down as soon as I saw the first few weeds growing thinking I could keep it from getting bad but it’s spread a lot. It ended up raining about 10 hours after I put it down also. My question is can I put down weed and feed if it’s only been 2 weeks since pre-emergent is different? (I live in TX and I have Bermuda grass) One last note when I moved in last fall roadside aster had taken over the yard, it’s all dead but the roots are still all across the yard and hard and thick and suggestions?

    Thank you!
    Brandon

    • Hi Brandon
      The pre-emergent you applied is to keep new seeds of crabgrass and other annual weeds from germinating this spring. For existing weeds in your Bermuda you have two options: You can put down Scotts Turf Builder Weed & Feed, or you can spray your weeds with Ortho Weed B Gon MAX and feed with Southern Turf Builder. The Ortho Weed B Gon MAX controls more different weeds than you will get with Weed & Feed. In both situations it is best to wait until your Bermuda is actively growing (when at least 60% of your Bermuda is green showing that it is coming out of winter dormancy). If the aster roots are dead, they will decompose. If the plant is just dormant, you can spray with Ortho Weed B Gon when you see new growth. Good Luck!

    Hi Ashton,

    I live in San Antonio, TX. We are a new homeowner and when we moved in our lawn was taken over by all kinds of weed. We tried pulling some of them out but it looks like more of them had came out in different areas. It’s pretty hard to water regularly here because of the water restrictions. What would you recommend for us to do so we can get rid of all these weeds and possibly prevent them from coming back? Thank you in advance! :)

    • Hi blumackey
      Based on where you live, you likely have St. Augustinegrass (which has a wide blade and forms a very thick lawn in both sun and lightly shaded areas). If you have this kind of grass, you can put down Scotts Bonus S Weed & Feed now and water after application. This product will not control all weeds, however it is your best choice right now on St. Augustinegras. The next most likely lawn type in your area is Bermudagrass (which has a finer blade texture and grows mainly in sunny areas). If you have this kind of grass you can apply Scotts Turf Builder Weed & Feed to moist foliage when there is no rain or irrigation for 24 hours.
