---- — If your lawn was looking a little weak with thin and/or had weedy patches last summer, and you didn’t improve it last fall, spring offers another opportunity. While the best time to work on improving your lawn in Indiana is from mid-August through mid-September, you can achieve very good results in early spring. This type of lawn improvement is referred to as "dormant seeding" because the grass seed will lie dormant until soil temperatures warm in April. It works by utilizing the natural processes of the earth to establish a good seedbed. In the spring, Central Indiana goes through frequent freezes and thaws where daytime temperatures are above freezing but it cools at night. The freezing and thawing action creates minute crevices in the soil surface. This creates a pretty good seedbed as the grass seed will fall into these crevices and later germinate. See Wednesday's Times Sentinel for the full story.
