March 1 - April 15
The second half of the pre-emergent will be applied for weeds such as crabgrass. This will be combined with a broadleaf killer for any breakthrough of weeds such as henbit or dandelions. Research shows that splitting the rate of the pre-emergent products into two applications will help with turf safety and provide better and extended control vs. applying a single dose of pre-emergent during the spring. Any needed post emergent herbicides will be applied by spot spray or within the broadcast mix to address weed issues that are present such as poa annua or winter grasses. This treatment will be activated by rainfall. Very rarely would there be a period long enough without rain to require irrigating the lawn. If it does not rain within 2 weeks make plans to irrigate the product with ½ inch of water for best results. A blue dye is added to this mix as a tool for our technicians to assure full spray coverage. Be cautious of pets when the product has not dried to avoid the risk of bringing the blue dye inside your home.
Lawns should be waking up from winter during this time and starting to green. Lawns may begin to green and then be hit with a frost turning it back to brown temporarily. The time of green up will vary depending on several factors. Some grasses in our area start to green in mid-March as others will be delayed into May. The specific cultivar of grass that you have in your yard will influence this greatly. Hybrid Bermudas such as Celebration and TifTuf Bermuda grasses are genetically improved for early spring green up. Soil temperature is the main factor determining green up of grasses. Bermuda grasses typically green up when the soil temperatures reach 65 degrees. This would usually occur when nighttime air temperatures are consistently above 60 degrees. You can help increase your soil temperature during this time by scalping and removing the brown dormant grass. Ideally this would be done roughly April 1st when the threat of frost and cold temperatures begins to decline. Cut as low as possible without cutting into the soil. It is important to remove these clippings by raking or bagging with a mower. Failure to pick up the clippings will cause issues from excessive thatch.
