There are a few theories on getting potatoes ready for planting. Some people wait for their potatoes to sprout and some people just plant them. Then there are those people who cut their potatoes and let them "callous over" by leaving them to sit for a couple of days. Some people just cut them right before they plant them. If your potatoes are small, you don't have to cut them at all, and can simply plant them. I let them sprout, then cut and plant on the same day.
When you cut your potatoes, make sure that you have at least two eyes on each piece of potato. They say that each piece should also be at least two ounces. I have no idea what two ounces of potato looks like, so I just guess. These seed potatoes were small, so I just planted them whole.
The plants will grow fairly large so make sure to give them some breathing room. This container is almost 20 inches wide, and I’ve planted four small potatoes. This will give you a bigger harvest than you would think possible.
