If you look at my labels to the right, you will notice that onions and potatoes top the list. Part of the reason is that they are two cool season vegetables that can be grown twice a year. The photo is of the last of our potatoes I harvested this week. I planted them in mid-February and have been pulling them up for the past month. Apparently you can plant a fall crop of potatoes in mid-July for harvest in November, before it gets too cold. No one I know that grows potatoes has done that, but I think I'm going to have to try it out.
The problem with that is that feed stores only sell potatoes in February. I may call around for the heck of it, but I don't expect results. I could try planting some I bought from the store, but I feel like I might be wasting my time with those. They are usually treated so they won't sprout. I thought about planting some that I have already grown, but I'm not sure about those either. There are also problems with catalogs too - the cost of shipping whole potatoes is not worth it. I did find a catalog that sold potato eyes, and I kept it, hoping they would still sell them when it was time to plant a second crop, but I've misplaced it at the moment. It seemed really reasonable - the price was good and shipping wouldn't cost as much since it was only the eyes and not the whole potatoes. Hopefully in the next month I'll be able to locate potatoes suitable to plant for a fall harvest.
