Grassy Weed Control

Grassy weeds and sedges are extremely hard to control due to the fact that they in the grass family. It will take special products to address these weeds and Family Tree and Turf has a special program for these specific problems.


The presence of weeds not only reduces the aesthetic quality of the turf, but more importantly they compete with the desired turfgrass for water, nutrients, and light. Failure to control weeds often results in a deterioration of the turfgrass stand over time. Weed infestations are often symptomatic of a more basic cultural or soil problem in many cases. If these problems persist, weeds also will be a continuous problem. Thus, a sound weed management strategy not only includes removal of existing weeds, but also using corrective management measures for the factors causing poor quality turfgrass.

Growing a healthy, dense, and vigorous turf is one of the best methods for reducing the potential infestation of weeds in turf. A vigorous, thick turf shades the weed seed and greatly reduces germination. There are several management practices that, when followed, will help to reduce weed encroachment. The following steps can lead to healthy, dense, and vigorous turf, which will resist weed invasion.

Family Tree can plant high quality seed of recommended cultivars. Plant seed of cool-season grasses between late August and early October. Avoid spring or summer seedings.

Soil Fertility testing should be performed every 2 to 3 years. Apply phosphorus, potassium, or lime based on recommendations of the soil test report.

Mow lawns at the recommended height. Leaving clippings recycles nutrients, sustains soil fertility, and provides for a healthy, vigorous turf that is more competitive against weeds. 

Water deeply by wetting the soil to a 4 to 6 inch depth. Frequent, light watering greatly encourages weed encroachment, discourages deeper rooting, and lowers the environmental stress tolerance of turfgrasses.

Turf Renovation

If grassy weeds become such a problem that you wish you could remove everything and start over, there is a way. In late summer apply Roundup to the weeds and grass. In a few days, as they start to die, scratch through the area with a rake or similar tool to expose soil. New grass seed can be sown in the area 7 days after treatment. Keep the area moist until the grass seeds germinate and begin growth.
