How To Grow Potatoes
A garden designer, Linsey Evans, goes through the process of growing new potatoes from seed potatoes. While first declaring potatoes as growing well in containers, she focuses on growing potatoes outside.
You grow new potatoes from seed potatoes which are just a potato collected from last year and kept. Buy them in bags from the garden center. There are different varieties and there are hundred of them and they are all described as either first earlies, second earlies or main crop varieties.
This tells you when the potato is ready for cropping. Obviously, the earlies are ready first, the second earlies are ready next, and then the main crop later. Potatoes grow really well in containers, but the containers must be at least 30 cm deep and wide.
Potatoes need lots of water, especially when they come into flower, which is when the tubers are actually forming underground. Dig over the ground where you're going to plant the potatoes in late autumn or early winter, and allow them frosts to break down the soil. Add some manure, well-rotted manure, or garden compost and add a couple of handfuls fish blood and bone meal per square meter.
Some people dig a trench to plant their potatoes, but I just do the individual holes for each potato. I dig a hole, 3 to 5 inches deep. Pop the potato with its eye facing upwards, being really careful not to break the shoots off, place it firmly in the hole, and cover it over.
First earlies, second earlies, and salad varieties, plant them 30 cm apart, 10 cm deep, and each row spaces 45 cm apart. Main crop varieties, plant them 15 cm apart, 10 cm deep, and the rows slightly wider, 60 cm apart. Giving them a dressing with a high potash fertilizer will increase the yield, but don't use too much nitrogen.
You'll hear people talking about earthing up potatoes. All this means is when the plants begin to show some signs of growth and they've got some green leafy growth on them, start covering then with a rich of soil. It helps to protect the growing potato tubers and it stops them from turning green, which means they are inedible.
You can start lifting your potatoes from June until September. If you're not sure about whether they're ready or not, just dig around the plant, put your hand underneath, and feel the potatoes to see how large they are. If they aren't quit ready, don't dig them yet.
And that's the sum of my tips for helping you get a good crop. A garden designer, Linsey Evans, goes through the process of growing new potatoes from seed potatoes. While first declaring potatoes as growing well in containers, she focuses on growing potatoes outside. .
