With the short cold season of Zone 8, I am already setting out squash plants. We are due for another frost, according to the almanac. but with the spell of warm weather we're having, I'm gonna go ahead and plant. I have others already started, just in case. All it costs is a few seed and a little time.
I start everything except peas, beans, and corn indoors and transplant outdoors when the soil temp begins to approach 65-70 degrees. I have a sun room and a sunny garage, and buy the peat pots & starter thingies in bulk and on closeouts, noy limiyrr on space. I don't grow onions or peppers; a neighbor plants waaaay too many of those every year and we swap.
I save heirloom seed from the squash, tomatoes, cantaloupes, melons, and edible gourds. Others I buy from Willhite's or the local feed store.
