Salad potatoes are great when steamed (or boiled if you must) and served with butter they also can be used to make potato salad of course. My favourite is Charlotte and I also like Nicola.
If you grow them yourself, you can harvest before the skins have formed or are so thin that you don’t have to bother peeling. This year, I’m growing Charlotte and Nicola varieties in 70 litre sacks in the greenhouse. I’ve done this before and have even started as early as January, but this year I planted at the beginning of March. For this, you’ll need 70 litre plastic woven sacks (I got mine off ebay around 5 years ago). You’ll also need some good compost, and this year, as always, I’m using Clover. If you have made your own compost over the past year, then use that as it works out much cheaper.
You’ll need to spread a layer of compost on the bottom of the sack (around 2 inches), then place a seed potato in each corner and one in the middle. Cover each seed potatoes with compost (again about 2 inches) and water. Keep watering regularly and after a while (mine took a couple of weeks), you’ll notice the plants start to push through the compost. Cover the growth with a layer of compost. Repeat this process (water, cover growth with compost), until the bag is full. You can then transfer the bag outside if you wish, but make sure that any chance of frost has passed. Potatoes are ready to harvest when the leaves start to die off. To test if ready, push your hand into the soil and pull one of the potatoes up. You really can’t beat the taste of home grown potatoes.
