Potatoes in Grow Bags April 2026

 

April 4, 2026 (original post on NextDoor)

First year planting potatoes in grow bags. Red seed potatoes in bag on the right. Yukon Gold seed potatoes in bag on the left. Three inches of garden soil + cow manure mix in the bags first -- seed potatoes with crowns pointing upward placed on this layer. Covered seed potatoes with 6 inches of soil mix and topped off the soil with handful of bone meal stirred in. Watered both bags really well. New potatoes will grow in the space above the seed potatoes. Once crowns show through the top layer of soil, more soil will be added. To harvest, I'll empty entire contents of each bag onto a tarp to remove new potatoes. Soil on tarp will be placed back in the grow bag for next use.

As the foliage (crowns) grew, I would add more potting soil leaving just the tops of the crowns showing.  I repeated this process as necessary until the soil reached about 1-2 inches from the top of the grow bags.  These are 10-gallon grow bags and are easier for me to handle and move than larger bags.

 

The foliage of potatoes is quite beautiful and large.  My understanding is the foliage will begin to wilt and die when it is time to harvest the potatoes.  I have added grass clipping as mulch.  Will post more photos at harvest.  After harvesting, will plant another round of seed potatoes to have before winter. 

 


Update:  7/3/2026

Potatoes were harvested!  Dumped bag contents on a tarp, pulled out potatoes, and put soil back in the bags to be used again.  The harvest was     ~5 lbs total for white and red potatoes.  I will not be planting potatoes again.  I don’t eat that many potatoes and not a good place for long term storage.  At least I know I CAN grow potatoes if the need arises.

 

 

Dumped each bag on tarp.  Rummaged through the dirt and removed all potatoes.  Put dirt back in grow bags to be used again.
