Growing Potatoes in Potato Growing Bags

Growing potatoes in sacks saves lots of space and doesn’t require a garden, - you can even grow on a balcony or small concreted yard.

Planting in Gro-Sacks

At the appropriate planting time, set five tubers on top of a 15-20cm (6-8in) layer of good quality compost in each Gro-Sack and then cover the tubers with a further 10cm (4in) layer of compost and fertiliser. As the plants grow and shoots emerge above the surface, add more compost to cover the shoots and then repeat as needed until the compost is about 5cm (2in) below the top of the bag.

As the plants grow and shoots emerge above the surface, add more compost to the potato growing sacks to cover the shoots and then repeat as needed until the compost is about 5cm (2in) below the top of the bag.

Keep the compost moist at all times but don't saturate it as this might cause the tubers to rot.
Feeding and watering Potatoes in Gro-Sacks

An application of a high potash fertiliser at the rate suggested on the pack will increase yields. Avoid fertilisers high in nitrogen as these will delay maturity of the crop.
Potatoes need plenty of moisture, particularly round about flowering time which is when the tubers start to form. An occasional heavy watering is better than little and often as this does not get down far enough and encourages shallow rooting.

 Harvesting and storing Potatoes in Gro-Sacks 

 First Earlies are best harvested in small quantities and eaten straightaway when fresh in May and June. Harvest when flowers are fully mature and open.

Second Earlies and Salad varieties can also be harvested in small quantities and eaten when fresh in June and July. Harvest when flowers are fully mature and open.

Maincrop varieties can be lifted from September onwards and stored as long as the tubers are lifted in dry conditions or are properly.

Harvest when leaves and stems have all yellowed, remove yellow stems and harvest potatoes a week later.

Store in a hessian sack in a cool, dark, frost-free area.
