Here goes... First off I'm about 30-45 mins west of Atlanta I'm sitting pretty smack dab on the line between 7a and 7b.
I bought a yellow bell pepper plant as a seedling from home depot. I've already had a bit of trouble with a tomato plant I bought at the same time turning out to be cherry rather than beefsteak and no amount of pruning or watering or fertilizing has changed the size of the tiny toms one bit... I have a ton of cherry tomatoes though

Also should I be pruning my pumpkin and melon vines, like you do with tomatoes?
Does anyone around know when I should be planting my fall harvest crops... the packets all say from july-aug. but then warn about them not germinating in hot weather... those are the two hottest months here...
My iceberg lettuce (which I was probably overly advantageous in thinking I could grow during summer season) bolted. Should I try and save seeds for a fall crop... If so how do I do that?
and lastly I've got some sort of pear tree in my beck yard, anyone got any advice on finding out more about it?
Thanks in advance!
