How to grow Jerusalem Artichokes

This is a very forgiving plant, that can be grow in a variety of different soils and conditions, and it will still produce well.

The best way to grow them is from tubers (growing from seeds is not recommended, as it is much more difficult – and finding the seeds will also be a real struggle!)

  1. Plant the tubers into well prepared, weed free soil, at about 4-6 inches deep. You can plant them in a garden, at an allotment, or in grow bags or large tubs.
  2. When the stems reach 12 inches tall, draw soil up around the bases to keep them stable as they grow. If the stems reach over 5 feet tall, you should trim them so they don’t get damaged and broken by the wind.
  3. They don’t need a lot of water, but if the weather is very dry for a prolonged period, then your artichokes will benefit from a drink.
  4. In the autumn, when the leaves start to turn yellow, prune them to about 3 inches above the ground. You can leave the prunings around the plant, to keep the soil warm and make lifting the tubers easier.
  5. You can harvest your artichokes from late autumn; they will be absolutely fine left in the ground for months at a time, so you only need to take what you want to use.
  6. Lift the roots carefully with a fork, loosening the soil around them until they can be removed.

If you want to keep your Jerusalem artichokes from taking over your whole garden, planting them in large pots is a good idea, so they won’t be able to spread.

Common pests

1. Slugs and snails

The bane of any gardener’s life, absolutely love baby artichokes. You’ll notice chewed leaves, and a trail of silvery slime around the plants.

You can combat theses pests using a variety of environmentally friendly methods such as egg shell, sawdust, copper tape and beer traps – or you can go down the slug pellet route, but always make sure the type you buy is safe for wildlife and the environment.

2. Sclerotina

It is a fungal disease that attacks Jerusalem artichokes, and unfortunately there is no cure. If you notice your plants rotting at the base and developing white fluffy mould, you need to immediately destroy these plants, to prevent the disease entering the soil. Do not compost the affected plants.

Dos and don’ts

  • Don’t overwater your Jerusalem artichokes. Too much water, or growing in waterlogged soil, can make the tubers rot.
  • Do make sure your artichokes have enough space. These are big plants that need a lot of growing room, and they won’t like to be too crowded.
  • Don’t leave any tubers in the ground once you have harvested. These tenacious little beauties will come back year after year, from just one forgotten tuber.
  • Do cook them well – Jerusalem artichokes contain a carbohydrate that can cause wind if not broken down by the cooking process.

Final words

Growing Jerusalem artichokes is easier than a lot of other vegetables, and they will reward you with large harvests that can improve your meals – and your health – throughout the year.
