How to Grow Potatoes in a Bag

Updated February 21, 2017

Growing potatoes in bags has several advantages. Bags give you greater control over the quality and type of soil used in your gardening. This is especially helpful if your garden has a poor quality soil that does not allow you to grow potatoes. Your growing season is also extended by growing potatoes in a bag, since the soil stays warmer and is protected from frost. Growing in bags is also simple and makes for an easy harvest.

Fill your compost bag a quarter of the way with good compost. Compost is available from all good gardening centres if you do not have your own compost pile.

Place potatoes that are growing eyes into your bag. Put only two or three.

Cover the potatoes with compost.

Poke the bag with a knife on the outside to create drainage holes.

Water the bag so that the soil is moist but not soaking wet.

Throw more compost onto the growth coming from the bag. Roll the compost bag up as the soil level fills.

Place the bag in a place that is free from frost. Water to keep the soil moist but not wet. Harvest the potatoes by splitting the bag in the summer.
