Spring Lawn Care – Crabgrass Prevention
As your lawn makes its recovery from the St. Louis winter, the focus of lawn care should start to include weed and crabgrass control by mid spring. The best time to begin applying crabgrass control is in mid to late March before it has time to fully mature. Weeds and crabgrass are more difficult to control once they develop and herbicides will have less of an effect on fully grown weeds. The most effective way to keep weeds and crabgrass under control through the whole season is to attack them before they develop within the root system.
Crabgrass is a common weed that grows annually and is characterized by its wide leaves that spread out to a diameter of up to 12 inches. One plant is capable of producing 150,000 seeds in a single season and the removal of crabgrass after it sprouts leaves dead spots in a lawn. The most effective way to prevent crabgrass is to attack it before it develops with preventative pre-emergent. Green T offers crabgrass pre-emergent with our lawn care service that creates a barrier in the soil to prevent crabgrass from germinating. This application can be quite effective in preventing crabgrass growth through the entire season if applied in mid to late March. However, applying crabgrass pre-emergent too early can be harmful to the germination of the grass seed. The crabgrass pre-emergent applied by Green T includes a 6 month guarantee.
As crabgrass control becomes a focus of lawn care in mid spring, it is important to continue with slow release fertilizer and other forms of weed control to promote your lawn’s recovery into a strong and healthy root system. A lawn’s best natural defense against weeds is strong roots and by continuing to apply slow release fertilizer along with weed and crabgrass pre-emergent, you can help strengthen your root system to help battle weed growth all season.
