45 days is what you need, give or take a week to 10 days before a good frost. If you use a compact bush variety you should be able to sneak some in. Usually here we dont see a frost until mid November. I usually dont need to plant for fall but got so little I have to. We got a decent rain yesterday and we arent expecting much from this hurricane here so we should be good to go. I planted Maters late so i could extend my harvest and the 1st batch was horrible due to teh weather...second planting is growing maters now so a few more weeks of moderate weather and we can put a few bushells up I believe
