There are two ways to harvest potatoes. You can get "new potatoes" which are ones you carefully dig up while the plant is still growing. And then there is the normal way, which is to wait until the plant begins to die back. I usually have one or two plants that I attack while they are still vigorous - but keep others to mature and die back without disturbance. You will always get more potatoes if you keep burying the plant in dirt and letting it grow through. It gives more stem to create lateral roots. good luck

Potatoes are ready to harvest when the plant dies and the tubers at here fullest of starch and size. If you are going to store them then wait until this time. You can start harvesting any time there is any size to the tubers (size of a baby's fist) but Cook and eat them straight away. Happy gardening-Timo

Why do you not grow Cucumbers and Potatos in the same garden bed?

Because they compete for nutrients and water and planting this way only diminishes potential harvest.

I have harvested my Dutch Cream potatoes, I'm a first time grower and seemed to get a reasonable crop. I would like to keep some to plant next year. How do I store them until next August? The seed potatoes I used were from an organic nursery.

I live in Southern California Zone 10A and grow potatoes year-round in bags and containers, anywhere from 5 to 15 gallons size. I have found what works well for me is to put about 4-6 inches of good soil in the container, lay a few seed potatoes on top so the slips are pointed up, about 12 inches apart, then cover them with about 4-6 inches of soil, and water moderately or they will rot. These potatoes will only produce new tubers in the soil about 6-12 inches above the original seed potatoes, so when the plants are about a foot above the soil, if I have any new add seed potatoes and the container has enough room, when I add more soil I may consider adding a few more seed potatoes that will produce "baby potatoes" above the older tubers, then cover them with another 6 inches of soil that will also bury more of the new growth of the first seed potatoes. Doing this stimulates more growth, and I may even add even more soil as the plants get taller depending on the depth of the container. I don't always add the second layer of seed potatoes, but doing this produces a few larger potatoes below (Baked Potatoes!) and a lot of smaller potatoes above them, and they are all excellent eating. I am growing Russet, Golden, and Red potatoes in containers, but I think they are all determinant varieties since they are all started from potatoes purchased in grocery stores, and each plant only produces tubers in the area near the seed potato, but do not continue to produce tubers as the plants get taller no matter how much more soil is added. I am still learning as I go, such as "location, location, location!" is making a noticeable difference on how successful my efforts are, and I would like to find an indeterminant variety potato that will grow well in Zone 10A.
