We are learning this one together and things are going great! Growing both potatoes and onions in grow bags has been a lot of fun and so easy! This is something I will continue year after year. I will, however, buy larger grow bags for the next crop. Gardening and growing our own food is a form of therapy for me and with our ever changing economy one that makes me feel a little more at ease.
One of the Yukon Golds has flowers. What does this mean? It means that the tubers are forming and growing and we will soon have some potatoes! We will continue to water them and wait. They will continue to grow for now.
WHAT SIZE GROW BAG DO I NEED? THE GROW BAGS I USED THIS YEAR ARE 10 GALLONS. THESE WORK PERFECTLY FOR THE ONIONS. I WILL USE 20 GALLON GROW BAGS FOR THE POTATOES IN THE FUTURE TO ALLOW THEM MORE POTENTIAL FOR PRODUCING A LARGER YIELD.

STEPS IN THE PROCESS
Since we planted our crops, covered them with good nutrient rich soil, and thoroughly watered them in Part One, they began to sprout and grow. We continued to water them all religiously and cover the potatoes every time they were six inches above the soil. Adding soil and giving them fertilizer help potatoes to produce more tubers. The tubers grow on stolon’s, underground stems, which are nodes that form low on the stems. This is why it is so important to continue to bury the stems so more nodes have a chance of creating stolon’s and producing more tubers.
As I have done this I am now seeing flowers beginning to form on the potatoes. This is a sign that the tubers are indeed forming and growing. About two weeks after the plants flower and start to die back is when we know the time has come for the harvest. We will then see what kind of yield we will end up with.

CAN YOU EAT POTATOES RIGHT AFTER HARVEST? Absolutely, you can. If you plan on long-term storage you will want to cure them and I will talk about that after the harvest. You can, however, eat them immediately.
HOW OFTEN DO POTATOES NEED WATERED? Generally potato plants need 1 – 2 inches of water per week. It also varies based on the soil they are in and weather. If it rains a lot you may not need to water them very often. Ours being planted in grow bags, I water them every couple days just trying to keep the soil moist but not too wet. We haven’t had much rain this year, so I am required to keep them watered.
