Hi Ann, A quick precis of what Monty says in that clip:
- Quarter-fill an old compost bag (bin liners usually aren't stong enough) with good quality compost. Roll the sides of the bag down to suit.
- Plant 3 seed potatoes (chitted for main crop types but no need to chit early types) and just cover them with enough compost so they are in the dark. 3 is enough and you won't get a larger crop by planting more.
- Water them, ensuring there are drainage holes in the bag, poke a knife in a few times to make them.
- As the green foliage appears, add more compost to completely bury it and unroll the bag as you go. Keep doing the same every couple of weeks or so until the bag is full. Water them regularly.
- After about 90 days they will be ready to harvest.
From me: Main crop types will take a bit longer - about another month.
