We plant three times a year. (
Arkansas)
Early spring is lettuces, broccoli, brussels, carrots, beets, radishes and all the other cool weather lovers (strawberries), we start these in late Feb.
Regular planting time (April to May) is when we plant just about all our vegetables, beans squashes, melons, sweet potatoes, etc.
Our fall garden combines both of the above and we start planting it at the end of august or mid September this is when the winter squash go in.
Our last harvest days are usually in the middle of December now, so we plan for this sort of weather pattern.
This year we also got some abnormal amounts of rain from January thru June, it took everyone by surprise.
I keep monthly and yearly records of winds, ambient temp., rain fall,
solar intensity and have done so for the past few decades.
This data base really helps with figuring out what to expect weather wise, it doesn't always fit perfectly but it gives me a way to get closer than those with no records to fall back on.
