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.
Do artichokes have deep roots?
Artichokes are deep-rooted and require adequate moisture when growing and producing fruit. Moisture stress may result in black tip, which is only cosmetic damage because the edible portion of the bud is not affected. Black tip is most common when conditions are sunny, warm and windy.
How deep are artichokes roots?
Artichoke plants have strong roots that grow deep and wide relative to their size. Their roots grow to be at least 6 inches (15 cm) deep and up to 3 feet (90 cm) wide in any direction. This keeps the plant firmly rooted and well-fed. It also means that artichokes need deep garden soil for adequate growth.
How do you get rid of artichoke plants?
Apply herbicide with a sprayer from midsummer to late autumn to get rid of Jerusalem artichoke rhizomes and tubers. Spray as soon as the plants reach a height of 8 to 12 inches. Spray again 10 days after the first application.
How do you keep Jerusalem artichokes from spreading?
A more effective way of managing Jerusalem artichoke weeds is to pull the young plants as soon as they emerge in spring– preferably when they are about 4 to 8 inches (10-20 cm.) tall. If you have a large patch of Jerusalem artichoke or if the plants are sprouting in your lawn, you can mow them down.
How much space does an artichoke plant need?
Artichoke plants require full sun, so if you plant them too closely together, the large plants can shade smaller ones. Plant your artichoke transplants in a row at an interval of 4 to 6 feet. Placing rows 6 to 8 feet apart will allow room to easily water, fertilize and harvest.
How long does an artichoke plant live?

How many years will an artichoke produce?
Quick Guide to Growing Artichokes

Do artichokes grow back every year?
For artichokes grown as perennials in the North, flowering stalks will be produced in the early spring, beginning the second year. After harvesting this spring crop, cut the flowering stalks to the ground to stimulate a second harvest in the fall.
Can you grow artichokes in pots?
Potted artichokes are easy to grow if you provide them with a large enough container. The plant can get quite big, and its root system is quite large. Perennial globe artichokes, for instance, can get 3 to 4 feet (a meter) tall and the same distance across.
Where do you cut an artichoke off the plant?
How to Harvest Artichokes

Can you leave Jerusalem artichokes in the ground?
They don’t generally store well once dug up, so leave them in the ground until needed. Jerusalem artichokes are persistent and will re-grow from any tubers left in the soil. So if you don’t want them coming back the following year, make sure you remove every last one.
What is the difference between artichoke and Jerusalem artichoke?
