Modified Growing Degree Days (Base 50°F, March 1 through May 24)
Insect development is temperature dependent. We can use degree days to help predict insect emergence and activity. Home, Yard, and Garden readers can use the links in this article with the degree day accumulations to determine what insect pests could be active in their area.

Gypsy Moth Caterpillars Active in Illinois
Gypsy moths are among some of the most destructive forest pests in the United States ... did you know they were brought here intentionally? They were originally intended to be used to increase disease resistance in hybridized silk spinning caterpillars, but the gypsy moth escaped the industry and became established in natural areas. From there it has slowly spread throughout the northeastern states south to Virginia and west to the Great Lakes Region; and into Illinois.

Cool-Season Perennial Grassy Weeds
I am often asked about controlling quackgrass and tall fescue. These cool-season perennial grasses can be difficult to eliminate from finer-textured, cool-season turfgrasses. Spring is the time of lush new growth for both most Illinois turf, as well as these unwanted grasses. If you haven't done so already, scout your landscapes for these weeds and plan your control tactics.

This article will address lawn injury from pet urine and how to repair damaged lawns.
