Really...you wait that late? Here I thought they needed to be in by the end of August!
Now I'm prepared too far in advance...I'll probably forget to plant them!
Okay...compost is good, I have plenty of that. My biggest concern is rot. Onions I can grow successfully in the flower beds but all of the ones I've tried in the veggie patch have failed. Do you wait a while after planting to add the compost? We're usually so very rainy and wet all the way up till the snow flies...
