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.

Most people grow potatoes from “seed potatoes”. Some people chose to grow their potatoes from actual seeds – think tomato seed. These seeds are called “True potato seeds”. The reasons to grow potatoes from TPS are numerous. The main reasons tend to be: more variety, and cultivating a variety that is well suited to your conditions. When the intent is to cultivate a variety well suited to your taste and growing conditions you generally purchase a package of say Andean TPS. This package will contain MANY different kinds of potatoes: flesh and skin colours. It will also contain short day, day neutral and long day potatoes; their ideal climates may differ. The idea is to grow as many of the potatoes as you can first year; some will grow well, some will not grow, some will grow poorly and some might just LOVE your place. Some will set a lot of potatoes, and some will set fewer; the idea is to find the potato/potato plant you like best – then save those potatoes to use as seed potatoes next year. In the first year you really don’t expect to have eating potatoes – it’s a year to find your potato variety. When growing from TPS you start the seeds early indoors, like you might do for tomatoes. Then transplant outdoors at the appropriate time.
