Jerusalem artichoke are like potatoes – while they do produce seeds, we never propagate them from seeds. Instead, plant tubers into the ground, which can be acquired by mail order or from selected garden centres and other growers. For best results plant in March or April. Plant tubers in small holes 30cm apart.
Do Jerusalem artichokes make seeds?
Jerusalem artichokes are grown from tubers, rather than seeds. These are available in March and April from garden centres and online suppliers. Choose a sunny planting site, where there is plenty of space, as these are large plants.
How does Jerusalem artichoke reproduce?
Because it grows so easily in a wide range of climates and soils, Jerusalem artichoke is sometimes considered weedy. Any tuber (or part of a tuber) left in the ground will form new shoots in spring and continue to multiply, so it can spread aggressively through a garden bed if not harvested every year.
Can you eat Jerusalem artichoke seeds?
They have a high level of inulin, which is a prebiotic fiber with medicinal properties. It can stimulate growth of bifidobacteria, which fights harmful bacteria and helps reduce certain carcinogenetic enzymes. Jerusalem artichokes are very versatile. You can eat them raw or cooked.
Can you leave Jerusalem artichokes in the ground?
Jerusalem Artichokes aren’t easy to store well but one of their advantages is that they’re quite happy left in the ground until you need them. If your ground tends to freeze, mulch well to ensure that you can extend the harvest period.
How do Jerusalem artichokes spread?
They spread by way of their tasty tubers, which divide beneath the soil. Even one tiny piece of tuber means a new plant the following year, and they’re almost impossible to irradicate. This can be good if they’re planted far from any other cultivated areas.
Do you cut back Jerusalem artichokes?
Cut back the plants once the leaves turn yellow, and then start to harvest the tubers in late autumn. The tubers will stand in the soil over winter but harvesting can be tricky in frozen conditions. Any tubers left in the soil will start growing again in the following spring.
Can I plant Jerusalem artichokes from the grocery store?
On March 1, we bought edible Jerusalem artichokes from a well-known grocery store and planted them in commercial potting soil in a re-used, covered plastic container. This type of container is great for starting any seed or tuber.
When should you harvest Jerusalem artichokes?
Jerusalem artichokes are generally ready for harvest when the leaves die down. If you have the patience you might want to wait for the first frost as tubers harvested after they got hit by the first frost taste sweeter. In my experience the best harvest season is end of september until march.
How do you prune Jerusalem artichokes?
Because they grow so tall (easily reaching ten feet or more), the plants can suffer wind-rock, or overshadow other crops. If this is likely to happen, cut stalks down to around 4 feet (120 cms) high in mid-summer. This will make them bush out and creates more compact plants.
Are Jerusalem artichokes invasive?
Jerusalem artichokes are considered invasive by some gardeners, and flowers should be cut before seeds develop if you don’t want the plant jumping the fence. If you’re worried, you can place starters in their own dedicated plot.
What happens when you eat too many Jerusalem artichokes?
Unfortunately, there are downsides to everything! As previously mentioned, in some people they may cause flatulence, and if very large amounts are taken, diarrhoea. FOS is more likely to cause problems than inulin.
Are green Jerusalem artichokes poisonous?
Watch out for: Jerusalem Artichokes will forge ahead without being worried by insects for the most part. Occasional leaf attack by chewing insects should not be detrimental to your harvest. If tubers become exposed as they mature, cover them with soil- as green tubers are poisonous.
Why do Jerusalem artichokes make you fart?
Jerusalem artichokes (Helianthus tuberosus) are rich in inulin, a form of starch that is not easily broken down by our bodies. Eat a lot at once and there’s no beating around it – you will fart a lot.
How do you overwinter Jerusalem artichokes?
Place them in plastic bags or in a container of damp sand in a cold root cellar or basement. At 32°F and high humidity, tubers will store for 2 to 5 months. Sunchokes stored in the refrigerator in a perforated plastic bag will keep for about 10 days. Tubers of the Jerusalem artichoke do not store as well as potatoes.
Do deer eat Jerusalem artichokes?
Deer and Artichokes
If deer discover your Jerusalem artichokes, they will be devoured quickly. Deer don’t sniff out newly planted tubers, but if the plant is growing, they will eat the leaves and flowers and follow the stem to the underground tuber, digging that out as well.

Are artichokes invasive?
New University of British Columbia research finds that the success of weedy and invasive plants like the Jerusalem artichoke lies in their genes. The tasty tubers, or root vegetables, of the Jerusalem artichoke may make for a nice side dish, but the plant is considered a major invasive species in Europe.
Should you peel Jerusalem artichokes?
Just scrub them clean – there’s no need to peel them (should you wish to, a teaspoon works well). If you do peel them, drop them into acidulated water until you’re ready to use them because the flesh discolours quickly. Keep an eye on them while cooking as they can turn to mush quite quickly.
Where are the seeds on an artichoke plant?
