Did you know that you can harvest Jerusalem artichoke all year round? This even has the advantage that you can keep the spread of the plant within limits.

Topnambur cannot be stored as long as potatoes. Plant vegetables and reward yourself twice. On the one hand you can enjoy the look of many vegetables, on the other hand you get a rich harvest. So of course also with the Jerusalem artichoke.

The earth artichoke is one of the simplest vegetable plants and is ideal for showing children and inexperienced gardeners the first steps of cultivation. We will explain below how you can reward yourself with the harvest after the growth and ripening phase.

Harvesting Jerusalem artichoke - you should know

Optimal location:

The Jerusalem artichoke harvest begins in autumn. During this time you can count on the largest tubers. In addition, the earth artichokes have the best flavor at this time.

If autumn is the ideal harvest time, the plant sprouts all year round. However, the tubers reflect the weather: if the summer is hot and the soil is drying, the tubers shrink because the plant draws water from them. Hot temperatures and dry weather conditions should therefore be avoided during the harvest.

The harvest:

If the soil is loose, you can easily pull the tubers out of the ground using the stem. Alternatively, simply dig out the plant and remove the tubers from the plant.

After harvesting, the plant will of course not grow again, so you will have to replant it in spring. If you have created a privacy screen with the vegetable plant, you can harvest every second tuber. In this way, half of the privacy screen remains in place and will sprout again in spring.

" Tip: Winter the perennial vegetable plant, you can cut back the perennial in autumn.

If you want fresh Jerusalem artichoke all year round, you should always keep the soil around the plant moist. In this way, the earth artichoke absorbs sufficient water through the roots and does not have to resort to the bulbs.

Store Jerusalem artichoke

It is often said that Jerusalem artichokes can be stored just as well as potatoes. However, this is not true. While potatoes can be stored in a cool and dark location without problems throughout the winter, the Jerusalem artichoke suffers from too late a tasting. The tubers lose moisture and shrink after harvesting.

To keep the tubers fresh for a few days after harvesting, place them in the refrigerator or in a cool location if possible. You do not need to clean the fruit before storing - the soil protects the tuber from drying out.

If you want to enjoy the winter vegetables fresh in late winter, you can use old home remedies:

Sand Storage:

Put sand in a bucket and put the harvested tuber with soil and roots in the sand. The tubers should be about five centimeters deep in the sand.

Land fill:

You can either dig an approximately 40 centimeter deep hole in the outside area or you can use a bucket. The location must be cool and dark. Put the harvested tubers back in the bucket and cover them with soil. If you use storage in an earthy hole, use a trick that was used until the last century.


Freezing the Jerusalem artichoke is of course associated with less effort. You only need to peel the tubers and then freeze them.
