Last year I planted peas in mid August and harvested them as snow peas for stir fry. They produced belter than the spring crop. If you've not grown peas before you will need to trellis them with something.I have an onion question. Last weeks storm flattened some of my onions. A few are still standing but many are lying flat. One guy told me that if they are bent over at or near the neck they are done and should be pulled. That true? I asked my mom and FIL, both of whom gardened a lot of years, and neither had heard of that.
Also, if I need to pull onions, and my carrots are almost ready to harvest, what can I plant this late in the summer? I don't like the idea of a bare garden for half the growing season. Is there a heat tolerant lettuce (I live in Central IA)?
