Black/Grey Potato Growing Bags

An easy and convenient way to grow potatoes on your patio. These durable black/grey potato growing bags hold 8 litres of compost and can be re-used, folding flat over winter and requiring minimal storage space. The black and grey colouring prevents light reaching the developing potato tubers for healthy and delicious crops; and absorbs heat for a quick start in the spring. Following on from this year's technical trials, we now recommend planting a single tuber per 8 litre bag - we noted a 186% increase in yield! We're pleased to have seen this verified in the March 2016 issue of Which? Gardening – the trials team did their own testing and experienced the same 186% boost in yield.

  1. Excellent Potato Bags

    By Stephanie Kelly 01-07-2014

    I have purchased many of these bags and they are fantastic, the first set of potatos I planted produced between 8 and 10 potatoes per bag nice new potato size. The second set produced 4-6 potatoes but they were a big sized potato suitable for mashing. I will definitely be purchasing more of these bags they are incredible and so convenient, I started them in the green house then positioned them on the patio.
