How To Grow Potatoes In A Bag. Potatoes need to go through the pre-germination process before planting in a bag or pot. Growing potatoes in a bag is a great way to turn out vegetables without a garden and all you need is soil potatoes and warm space.
Where to grow potatoes All potatoes do best grown in a light warm sunny spot. Cover with another 8-10cm of compost and water well. Gently cover the tuber with compost.
Continue to water as needed to keep the deep plant roots moist not wet.
Fold down the top edge of the bag to form a 4 cuff. Add enough soil so that just the top few leaves poke through the dirt. You want the plant to have plenty of room to send off new roots in order to create more potatoes. When the potato plants get about 6 to 8 tall it is time to add more soil and straw to the bag.
