Gardeners with limited space can still grow bulk carbohydrates, though I am minded that this is more about quality of on the doorstep fresh organic flavoursome etc. than about basic survival.
This year I have grown a total of 9 bags of salad potatoes. The seed I used was simply a co-op supermarket scrap price bag, one and a half kg for 40p; which also provided a couple of meals. The bags used are the black plastic sacks in which our local municipal compost is packed.
Each bag was started with a few handsful of sticks and twigs, then a mixture of molehill soil, municipal compost, some leafmould and a handful of sand is the growing medium. Two seeds in each bag, chitted to get started.
During the summer weeks the bags were being fed/ watered daily with a decoction of nettle water (see the page on grow your own fertiliser) at a rate of approximately a litre per day.
Here all nine bags are in full leaf, watched constantly for any signs of blight, which has been a problem in the past 🙁
And today, with the tops dying back it was time to harvest.
This is the combined crop from two bags (for illustration –
the quantity and quality was consistent across the bags. The
four roots set aside represent the original seed.
This lot weighed in at just over 7 kg.
