From Houston: What fertilizer and pre-emergent weed killer should I apply now?
Fall fertilization is the key to prolonging Fall color and promoting early Spring recovery of lawns. It will also help to promote a thick turf which resists those Winter weeds. Calloway’s Premium Lawn Food supplies three sources of nitrogen. The first source provides a quick shot of nitrogen to give your lawn a nice greening effect. The other two are control-released to provide a consistent supply of nitrogen over the next several months. The 21-5-10 formula also supplies the needed nutrients to stimulate root development, make your grass hardier for the Winter months and provide food for next Spring’s growth! Apply it this month (September) or the first of October. For organic gardeners, Calloway’s Organic Fertilizer contains seven food grade meals and can also be applied now.
Because many weeds grow and strengthen while grass is dormant, pre-emergent weed control is important for Texas lawns. A pre-emergent weed control must be done before the weeds are growing. So, the best times to treat lawn weeds with a pre-emergent herbicide are September and mid-March. Apply Green Light Crabgrass Preventer with Dimension for grassy weeds and Portrait for those pesky broadleaf weeds. For our organic gardeners, Corn Gluten Meal has been known to be a natural pre-emergent.
