Hot weather in early July brought on some severe summer patch (root disease) symptoms in hard fescue. This disease on fine fescues hasn’t been as thoroughly studied as it has been on other grasses.

Rectangles of Melting Snow
Made an interesting observation while inspecting this trial for geese damage last December; rectangular plots of snow melting faster than other plots. Not sure of ramifications, but snow cover on some treatments was melted or melting faster compared to other treatments. This trial has numerous combinations of topdressing sands and rates as well as hollow […]
