Southern Lawn Tips for March

March 7, 2018

You can help make your lawn denser and thicker by feeding regularly during the year. Four to five feedings a year at 2-month intervals really helps your grass grow deeper roots and crowd out young weeds before they get a chance to get a toehold. (Note: Centipede Grass should only be fed two or three times a year.)


This lawn owner feeds her St. Augustine grass lawn on a regular schedule. Most lawns thrive with 4 or 5 feedings a year.

For southern Lawns this month your option if you have no weeds or only a few weeds is to feed with Scotts Turf Builder OR Scotts GreenMAX Lawn Food. You can spot treat any stray weeds if needed (more later).

If you have more than a few weeds you can apply a Weed & Feed designed for your type of lawn:
Scotts Bonus S Southern Weed & Feed – use on St. Augustinegrass (including Floratam). Apply to a dry lawn and water after spreading. (Note: This product can also be used on Zoysia and Centipedegrass lawns, however Turf Builder Weed & Feed may be a better option for these lawns depending on the weeds you are trying to kill.) New Scotts Turf Builder Southern Triple Action controls fire ants as well as weeds while it feeds.
Scotts Turf Builder Weed & Feed – use on all Southern Lawns except St. Augustinegrass. Apply to a moist lawn and do not water for 24 hours after spreading.

If you just have a few scattered weeds you can spot spray them with one of these weed killers:
Ortho Nutsedge Killer (this spray kills other weeds beside Nutgrass) – Can be used on any Southern lawn
Ortho Weed-B-Gon MAX for Northern and Southern Lawns – Can be used on any Southern lawn except Floratam (a type of St. Augustinegrass)
Ortho Weed-B-Gon MAX plus Crabgrass Killer – Can be used only on these southern lawns: Bermudagrass and Zoysia.

And finally, Spring rains and warmer weather are encouraging fire ant mounds to show up. I have had great success with the Ortho 2-Step approach to kill the fire ants I see and control the ones I don’t see.

Step 1 – Kill the Mound: Treat mounds you see with Ortho Orthene Fire Ant Killer. This product is designed to kill the queen and destroy the mound. Do not disturb the mound prior to treating. Sprinkle a tablespoon of product over and around each mound and do not water. Over the next several days the ants and queen in the mound will be killed.

Step 2 – Protect the Ground: Treating only the mounds you see is not enough to completely get rid of fire ants. That is because not all fire ant mounds are easily seen.  Colonies may remain active underground, hidden from sight. Additionally, new queens can fly in to establish colonies or foraging fire ants may enter the yard to look for food. Use a lawn spreader to put down Ortho MAX Fire Ant Killer Broadcast Granules to protect your lawn by killing foraging fire ants and controlling new fire ant mounds from forming for up to six months. Water your lawn after spreading the granules.

    Hi Ashton, my bermuda lawn isn’t green yet, just a few green sprigs coming up. I have a lot of weeds (hairy bittercress and others) that are beyond hand pulling. Am I able to apply weed and feed now or do I have to wait until the lawn is green? I am in NW Arkansas and temps are in the temps are in the 60s and 70s this week if that matters. Thanks in advance!

    • Hi Ashley
      Thanks for giving me your location. It is best to wait until you see about 50% of your Bermuda starting to green up before putting down the Turf Builder Weed & Feed. Based on your temps you should start to see more greening very soon. When you apply, put on moist foliage on a day when rain is not expected for 24 hours. Application first thing in the morning when you see dew on the grass works well and the ideal temps would be in the 60s and 70s.
