Tips for Spring Green Up

Most grasses turn an off color in the winter months here in the Midwest. Zoysia and Bermuda turn completely straw brown in late October, while DuraBlend Tall Fescue and Kentucky Bluegrass will only brown slightly starting in December.

Everyone wants their lawn to look super green as soon as possible each Spring (preferably before your neighbors' lawns). Here are some helpful tips to encourage green up each year:

  1. Keep the grass mowed very short. Its important to wait until temperatures warm up a little from winter. The best time to do this is early to mid-April in the Chicagoland area. Mow Tall Fescue and Kentucky bluegrass down to about an inch and a half. Zoysia and Bermuda can be mowed as low as one inch in late April. This will do 2 things: it trims off the yellow dormant grass blade leaving the new green growth exposed, and also allows more sunlight to reach the soil. Soil temperature is a major driver for green up and new growth.

  2. Remember to fertilize your lawn.Wait until the grass has naturally started to green up (Early April for cool season grasses, and late April for Zoysia and Bermuda). Fertilizer provides much needed nutrients that encourage healthy growth.

  3. Be patient. Grass turns dormant each year to protect itself from cold winters. Dormancy allows grass to reduce its energy use when photosynthesis is happening at a reduced rate.
