Not sure when to apply pre emergent to your lawn in South Texas? Late February is the time to apply a Spring pre emergent to your lawn in this area. With the 80 degree days in between all these cold fronts, weeds are popping up. The sooner these weed preventers can be applied, the better control of weed germination.
For organic solutions, use a corn gluten meal. There are twenty-two weed species that have been screened for susceptibility to corn gluten meal: Black Medic, Black Nightshade, Buckhorn Plantain, Catchweed, Bedstraw, Common Lambsquarter, Curly Dock, Dandelion, Purslane, Redroot Pigweed, Velvet-leaf, Annual Bluegrass, Creeping Bentgrass, Giant Foxtail, Large Crabgrass Orchardgrass, Quackgrass, Shattercane, Smooth Crabgrass, Wooly Cupgrass and Yellow Foxtail. Corn gluten meal significantly reduced plant survival, shoot length and root development of all tested species. Apply corn gluten meal at the rate of 20 pounds per 1,000 square feet.
Synthetic/Chemical Pre Emergent
A chemical or synthetically-produced pre emergent can also be used to control weed germination. At Mumme’s Inc, we carry Hi-Yield Crabgrass Control and Balan Crabgrass Preventer. Stop in any of our locations and we’ll be happy to talk with you about which pre-emergent option may be the best fit for your lawn or landscape area.
Looking to control grassy pastures? Try Triclopyr 4, an herbicide to control Woody Plants, Annuals and Perennial Broadleaf Weeds in Forests, Grass Pastures, Rangeland, CRP acres, Rights-of-Way, and in Non-Crop Areas and Ornamental Turf, Industrial Sites and Non-Irrigation Ditch Banks.
Always read and follow all label directions. Never apply a pre-emergent where lawn over seeding will be done or in vegetable gardens. The sooner a pre-emergent is applied the better control you’ll have over the weeds this season.
