Q. I have a good bit of thatch in my lawn. Can I rake or possibly burn it out at the end of this growing season?
A. Many times, what people are calling thatch is really not thatch - it's just dead grass blades on the soil surface. True thatch cannot easily be removed. Thatch is a layer of mostly dead grass stems, runners and roots. It is a layer that builds up over time between the sod and soil. This layer may look somewhat like peat moss. Dead leaf blades breakdown too fast to contribute

Do you have the weed that resembles miniature mimosa trees? If so, you’re not alone.
This common, troublesome weed is called chamberbitter or botanically Phyllanthus urinaria. It can be controlled with correct timing and persistence.
Chamberbitter is a summer annual that requires warm soil conditions to germinate. It has numerous, small, round fruit attached to the undersides of its leaf stems.

Q. I see webs at the ends of branches in some of my trees. Should I be concerned?
A. These are fall webworms. These worms (caterpillars) enclose leaves and the ends of branches with silken webbing. They are found in this protective webbing consuming leaves. Although they can defoliate branches on which they are feeding, very little to no permanent damage is done to the tree. It is more of an aesthetic problem. What they are feeding on is a temporary part of the plant - the leaves.
During the past few weeks numerous people have contacted the Okaloosa County Extension Office seeking diagnostic assistance and control options concerning fall armyworms and sod webworms in turfgrass. This includes farmers with these critters in their pastures and homeowners whose lawns are being eaten away by these hungry caterpillars. We’ve even had requests for help from a local landfill and from a local airport with grass runways.
