Sprayed with glysophate to kill Lesser Celadine which invaded the grass for the third year the first year I spot sprayed, but obviously did not get all of it came back with a vengeance this year. Lesser Celadine starts growing in early March and it is difficult to spray have to have temperatures close to 60°. It is very invasive. It started in the woods and I tried to spray along my fence line have gotten different opinions. Should we till or use aeration and reseed or just wait until next year and see if it pops up again, obviously we will have to spray again because different weeds will come up this summer. The yard is compacted not sure if it’s ever been aerated. Not sure if.Tilling will spread the tubers if not completely dead. If we do use grass seed, which is the best it probably only gets about four hours of sun many large trees. Three dogs one likes to play ball for a half hour at a time. Will fence off the part that is reseeded if we do that
