| Winter |
Postemergence weed control |
To control winter annual and perennial weeds. |
This application combined with the previous fall application is very important in eliminating the early spring "weedy look" seen in many lawns. |
| Late winter |
Preemergence weed control |
Controls summer annual grasses such as crabgrass and certain broadleaf weeds that germinate in the spring when soil temperature reaches 55°F for 4 or more days. |
Preemergence herbicides stop weeds as they germinate, or in the very early seedling stage. Therefore, they should be applied prior to seed germination. |
| Spring |
Fertilizer + spot spray for special weeds unique to your lawn. |
The proper rate of slow-release nitrogen fertilizer source provides healthy green-up without producing excessive growth. |
We go easy on the nitrogen fertilizer here because warm season grasses are just waking up from winter. If weeds haven't been fully controlled by this time, excessive fertilization can make matters worse. |
| Late spring |
Preemergence weed control + fertilizer |
To control later germinating summer annual weeds such as goosegrass. Supplemental nitrogen fertilizer helps warm season grasses perform their best at this time. |
This herbicide application should follow the late winter preemergence herbicide application for best results. Bermudagrass is beginning to look its best during this part of the season. |
| Mid summer |
Fertilizer + spot spray for special weeds unique to your lawn. |
Mid summer maintenance fertilizer application. |
This fertilizer application helps your warm season grass keep going when other plants have given up in the heat. |
| Late summer |
Fertilizer + spot spray for special weeds unique to your lawn. |
A maintenance fertilizer application based on soil test recommendations to help warm season turf develop a strong, healthy structure before entering winter dormancy in the fall. |
Warm season grasses that enter dormancy in a healthy
condition will have a much nicer winter appearance. There are
added benefits in weed control from the strong late-summer
turf. |
| Mid to late fall |
Postemergence weed control |
To control winter annual and perennial weeds. |
This application combined with a late winter application is very important in eliminating the early spring "weedy look" seen in many lawns. |
