Lawns are growing very good right now. Many are regreening and you can see the runners filling in. I am convinced grass likes to grow at this time of the year but so do the weeds.
We often call these the cool season weeds but some grow year-round. Some in my yard that just seemed to pop up overnight include the yellow woodsorrel and heart leaf drymary. But you can also expect the chick weed, dollar weed and many others to flourish soon too. They like the cool weather even more.
One thing for sure, if you do not control the weeds at this time they can over grow the lawn. Weed control can be as simple as digging them out. If you only have a few, use a trowel to remove them from the lawn. Digging a little in the soil can also loosen the ground and help the grass grow better too.
Weed control products are often of choice when there are extensive weed infestations. Be sure to select a weed control product for your lawn type. Read the small print as some products cannot be used with certain varieties of St. Augustine and other grasses. Then follow the label carefully.
Liquid weed control products seem to work best for most home gardeners. You are welcome to use weed & feeds but feeding time for lawns is over and these products are often hard to apply properly. When using the liquids follow the label instructions and spray them lightly over the top of the weedy areas. Concentrating them may damage the grass so be careful. Also, do not water for a few days unless otherwise instructed on the label. You want the herbicide to go into the leaves of the weeds and then through the roots.
Lastly, you do not have to treat the whole lawn unless it is weed infested. Spot weed control is often best at this time of the year. Also, don't expect products to control all your weeds. If you have problem weeds, take samples to your local University of Florida Extension office to have them checked.
