Dogfish, I am not much of a gardner, I try but I just don't seem to have a reall good green thumb? Something to think about. I used to live in McCleary, and that has a little different growing season than say Olympia area. It seems to be a longer season there? There has been a lot of good advise. Some things can be planted now. I usually follow what one of my neighbors does. And he has onion starts in already. Ask aorund there, for some reason the Elma McCleary area has an earlier start season and a longer end season. The time is at hand. Oh and it sounds like with 1 year old horse manure in there. You should have a great crop. You will get a ton of weeds though!!
God Luck
