Answer: Anywhere the turf gets thin, weed species like Dallisgrass can germinate and crop up. Long term solution to most weed problems is to build the densest, healthiest turf through proper mowing, watering and fertilizing. However, a perennial weed like Dallisgrass will compete and survive well once established.
There is not a product that will kill the Dallisgrass without harming other grasses. Some gardeners use a wiper or wick type applicator to carefully spot treat the weed without harming the grass. These applicators are available at many garden centers or home and garden supply stores.
