We have 1/4 acre garden. It's a major amount of work. So we cut corners where we can to save time. I start sweet potatoes in March, 60 days ahead of planting. I pick out tubers from last years harvest, usually medium size, although this is a good way to use small ones that are still good. I stick 3 toothpicks around the sides and suspend the tubers vertically in a jar (like pints) of water, halfway in and halfway out of the water. In a few days, the tubers will start to sprout roots and slips. When the slips have 4 leaves, clip them off and put them in another jar of water 1/2 full. The slips will begin to grow roots, when the single roots start to have small branches on them, take them out of the water and plant them in dirt in a container. I use tapered slick "dixe" cups, because you do not need drainage holes (no mess) and the slick cups make getting the plants out easy. I reuse the cups as long as they aren't severely broken. For the last plants, I just plant the whole tuber. In the garden, I hill up two ridges 3 to 4 feet apart and as long as the number of plants. I usually plant 50 plants, each plant about 16" apart. Water well as needed, if you get twisted curly tubers, that usually means not enough water. I usually harvest in late September (SW Missouri) with a potato fork. After the weather turns cool, they don't grow much, and in October sometimes the mice have a tendency to munch on the tubers, then the garden snakes follow and munch on the mice, and then it makes for fun digging, but hey the snakes are doing their job. I really like the variety that I grow, I do not know what it is, my mom started growing it 30 years ago, after trying several different varieties, and we still got it. It's "best" characteristics is good size, high production, great taste, fine grain and the tubers grow underneath the original plant. Nothing more frustrating than digging taters that are all over the place. Production is usually 10-12, 5 gallon buckets. After harvest, I spread them out on the lawn and hose the dirt off them. I let them dry and put them into paper sacks and then into the big pantry in the game room. Winter temperatures there are probably in the 65-70 degree range. They keep until the following year, and then we start all over again.
