Show LAWN & GARDEN CARE . . . ask the expertsl SPOT LAWN WEED CONTROL Q. I have been unable to control the crabgTass and other weeds in my lawn with regular maintenance, and they have taken over a goodly portion of it What do I do? A. Most weeds can be controlled in the spring with a spray program. Annuals such as crabgTass, dropseed, foxtail, and goosegrass are, according to the National Sprayer and Duster Association, most successfully controlled with a pre-emergence herbicide which should be applied prior to seed germination. See your garden supply retailer or county agent for assistance assist-ance in choosing the right weed control material for your lawn. Always follow label instructions carefully. Q. My lawn has many bare spots in it; what is the best way for me to keep it thick and healthy? A. Keep in mind that a thick, healthy turf helps prevent crabgrass and other troublesome weeds. Weeds, like other plants, need moisture and nutrients to survive. If your lawn is so thick that there's no place for weeds to start, then weeds won't have a chance. Good cultural practices, including regular mowing, watering, and spraying for insects and disease, help develop a dense turf and prevent weed invasion through the season. |
