Frost seeded my pond bank in northern Kentucky last March 1st. Generally the same weather, frost dates, etc, as SW PA.
Started with this - on the left side of this pic. Weeds had been bush hogged by prior Owner in Fall of 2011.
After a couple of mowings to get ahead of the weeds, I had this in fall 2012. Taken from the opposite end of the opening from above pic.
Area is only 1/10 acre, and about half of that has quite a bit of fescue. Where the fescue is, the clover did not do as well, but some did make it. I already frost seeded this again a couple weeks ago, and will spray the fescue in April, to try to improve on what's already a decent clover patch. This little patch saw heavy use from the deer in Nov/Dec.
Clethodim. Actually, the KY dept of fish & wildlife will provide me with the herbicide, since I have fescue to get rid of in some other fields. The biologist mentioned Cleth, but if he substitutes something else, I'll be using that instead.
not going to frost seed our plot. I'm mowing about 1/2 acre plot (currently about head high briars, weeds, overgrown field) this friday. Going to mow and plow it, and if needed before planting i'll spray any weeds that are sprouting with glyphosate. Going to do a white/red mix probaly early to mid april.
