This potato grow bag is a great way to grow 4-6 seed potatoes or other deep root vegetables without the need for lots of space. It has a resealable window for easy harvesting of new potatoes.
The bag has a 40cm diameter and is 55cm in height and has strong webbing handles. It is made from strong, woven UV-protected polyethylene which allows roots to breathe and will last many years of use.
Fill the bottom of the bag with 10cm of 1:1 straw and compost mix. Place 4-6 seed potatoes on top and add another 10cm of the soil mix to cover the top of the tubers. Keep the soil mix moist and place in a sunny position. As the tubers sprout, the green shoots will emerge from the soil. Periodically add 5-7cm of soil mix to cover these shoots leaving only the tips exposed. Once the soil is at the top of the bag, allow the plants to flower. From this stage, you can begin to steal new potatoes from the resealable window. Once the plant has died back, you can empty the bag and yield the full rewards.
