Growing Potatoes in a Bag

I had a bunch of potatoes accidentally kept in a closed pantry and when I saw them, they already have sprouted. LOL!  🙂

So instead of throwing them away, I decided to plant them in a garden bag I got from Bunnings since we don’t have much space in our yard.

To get started,  you need to have:

  • Garden Bag / Huge Pot or container
  • Garden soil mix
  • and of course,  Potatoes with several eyes on them.


  1. Cut the potatoes into half that have several eyes on them. Small potatoes can be planted as they are.
  2. Half-fill the bag/s with Garden soil mix.
  3. Place the seed potato 4 to 7 inches apart.
  4. Cover them with 3-4 inches of  the garden soil mix.
  5. As shoots appear, cover potatoes with more soil after they grow 6-7 inches and continue to cover the small plants until you reach the top of the bag.
  6. You can also add mulch to help retain moisture.
  7. Keep potatoes well watered but not soggy.

The potatoes matures in 70 to 90 days but some potatoes take 120 days until harvest.

I prefer using a garden bag because they breathe and drain well. Also, make sure there’s enough room to build up the soil as the spuds grow and this encourages the formation of even more tubers in layers.

Best condition for growing potatoes:

Place the  bags or container somewhere in your house that has at least 8 hours of exposure in full sun. 

Harvesting Time:

  • 3-4 months after planting.
  • Potatoes  is ready for harvesting after the plants flowered and died down.
  • You can also remove new potatoes before flowering.
  • Once the stems turn yellow, stop watering and wait a week.
  • Dig out the potatoes and sort through the medium for the tubers.
  • You don’t need to collect all your potatoes at once – harvest when you need them (so choose the largest ones first!) and leave the remainder in the soil until they’re needed.
  • Clean the potatoes and let them cure for two weeks for storage.
