Growing your own potatoes needn't require lots of hard work and space in the garden. Any space will do - you can even grow potatoes on your patio or balcony by growing them in bags.

Watch Alan Titchmarsh's video guide to planting potatoes.

Producing a healthy crop of potatoes in a bag, such as a compost bag, is much easier than you might think, and it's space-saving too. There's no earthing-up required, no digging and minimal mess. You can simply plant your seed potatoes in the bag, and wait for them to grow.

Plant potatoes in bags from February to April (depending on their type) for a crop between June to October. You can also plant successively to extend the harvest period.

You will need

  • Compost bag
  • Multi-purpose compost
  • Seed potatoes


Salad potatoes grow well in compost bags inside the greenhouse or in a frost-free part of your garden. Start by making drainage slits in the base of the bag with a knife.

Remove half to two- thirds of the compost and put it aside to reuse later for covering the shoots as they develop.

Bury two or three well- sprouted seed potatoes in the compost – any more and you’ll reduce the yield from each bag.

There's no earthing-up required, no digging and minimal mess.

Water well, two to three times a week, to ensure the compost never dries out. Once shoots break through, roughly every seven to 10 days, cover over with compost, until the bag's full.
