Lawn Weed Killing Options
The first line of defense against weeds taking over your lawn is to make your lawn denser and thicker by feeding regularly during the year. Three to five feedings a year really helps your grass 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.) The second defense is to mow your grass at one of the higher settings on your mower.
Here are options for killing weeds in your lawn:
(Note: if you have a Southern lawn, click here to link to my March 14 blog posting listing all your options.)
Option 1: If you want to kill weeds while feeding your lawn here are your product options:
Scotts Turf Builder Weed & Feed – use on all lawns except St. Augustinegrass and Bentgrass. Apply to a moist lawn and do not water for 24 hours after spreading.
Scotts Turf Builder with Halts Crabgrass Preventer – Use on all lawn. There is still time to prevent crabgrass in many northern areas. This product should be applied before you start to see wide spread dandelion puffballs.
Option 2: If you want to kill weeds without feeding your lawn here are product options:
Ortho Nutsedge Killer (this spray kills other weeds beside Nutsedge including Wild Onion) – Can be used on any lawn
Ortho Weed-B-Gon MAX plus Crabgrass Killer – Can be used on any lawn except St. Augustinegrass, Bahia, and Centipedgrass.
Ortho Weed-B-Gon Chickweed, Clover & Oxalis Killer – Can be used on any lawn except St. Augustinegrass, Bahia, Bermuda and Centipede. This spray also does a great job of killing Ground Ivy (Creeping Charlie) and Wild Violets.
Roundup For Lawns – Can be used on Kentucky bluegrass, perennial ryegrass, fescue species (including tall, red and fine leaf varieties), bermudagrass, buffalograss and zoysiagrass. (Application to bermudagrass may cause temporary yellowing or discoloration but full recovery can be expected.)
