January 1 - February 28
This round begins for during the first part of January and will go through the end of February. More time for this round is allowed as weather conditions are taken into consideration. Any time during this window is ideal to receive the first portion of pre-emergent herbicide to prevent weeds such as crabgrass during the summer. Warm season grasses such as Bermuda and Zoysia, even dormant, are often sensitive to damage during this time as they prepare for green up. 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. We will also apply any needed post emergent herbicides to address weed issues that are currently present. This may be done by spot spray or by adding herbicide to the broadcast mix. This treatment will be activated by rainfall. Very rarely would we have a period long enough without rain to require irrigating your 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 not require much maintenance during this period unless leaves were not removed or mulched during December. If leaves are removed during this period with a mower, do so with the blades as high as possible and avoid scalping. Leave the cutting height high during this time of cold temperatures to insulate the soil and help with erosion issues from constant rains. Shown are pictures of dormant warm season grasses such as Bermuda and Zoysia. If a combination of grass is present, Zoysia may have some green at the base and will have more of a yellow tint than dormant Bermuda grass.
