Have you noticed anything like this on any of your plants?  These disgusting-looking leaves on Fragrant Sumac are exhibiting Eriophyid Mite damage.  The mites are microscopic (1/100" in length), and their presence isn't noticed until their feeding causes plant damage such as the galls above or leaf curling, blistering or other deformities.  Fortunately, these mites rarely cause serious harm to plants, and control is seldom needed. If you garden, you are very likely to encounter these mites sometime in your gardening future.

Overseeding lawns consisting of Cool season grasses should be done in late summer or early fall. There are many reasons for this. With fall germination, the young grass will have two or three months to become better established before temperatures drop too low and growth stops. Next spring, the young plants will have another few months to develop deeper roots before the summer heat sets in. This is the primary reason, but there are also other reasons for overseeding lawns in the fall. Below are a few:

*	Overseeding lawns in fall reduces or eliminates competition from summer weedy grasses, such as crabgrass, foxtails, and other weeds.
*	Soil temperatures are still warm in the fall, which is necessary for seed germination, while the cooler air temperatures are better for grass growth.
*	Rain amounts and soil moisture is generally better in the fall.

Overseeding lawns in the fall gives the grass a head start. The roots have become established before winter, which greatly reduces crop loss should you have a hot, dry spring.
