calculating time to start seeds, if you start them outside
Sorry if this is a basic question, I snooped around in several forums and didn't see this exact issue.
I want to start a bunch of tomatoes from seed, but I grow my seedlings outside (no space inside).
I know you are supposed to calculate back from your last frost date, to know when to "plant out," and thus when to start the seed, but since mine will be "out" the whole time, does that make a difference?
I believe normally you are supposed to get your last frost date, then count 6-8 weeks backward. Should I just stick with that to be safe?
I garden on a patio that has warm spots, usually even when it's cold.
Thanks for any suggestions!
