I am south of I-10 in MS and some call it a wishfull 9:-)
I've just recently gotten into gardening since I found "Gardening in the Humid South" by O'Rourke and Standifer. This is an excellent text on gardening in areas with high rainfall, poor soil, and mild winters. According to planting calender in that book, cucumbers should be direct seeded in August for a winter garden. Hope this helps.
