P = Plant tubers

  • Easy to grow. Plant tubers about 5cm (1.5") deep.. Best planted at soil temperatures between 8°C and 15°C. (Show °F/in)
  • Space plants: 30 - 45 cm apart
  • Harvest in 15-20 weeks.
  • Compatible with (can grow beside): Tomatoes, cucumbers
  • Artichoke harvest

These are the edible root of a sunflower. Plant the tubers deep enough to cover with soil. They are quite drought-tolerant, but keep well-watered to grow larger tubers. They grow through the summer to 1.5m-tall sunflowers with a smallish flower. Dig up the tubers when the flowers die down in autumn.

Get a couple of tubers from the supermarket or fruit shop. Two years after planting you will probably have enough to give away. Perennial, if you don't manage to harvest all the tubers - they will regrow year after year.

Culinary hints - cooking and eating Jerusalem Artichokes

Scrape clean or peel (add a tsp of lemon or vinegar to the water to stop the tubers browning). Steam, boil, or use in artichoke soup (make with artichokes and some stock). Caution - because they contain 'resistent starch' Jerusalem Artichokes are a great promoter of flatulence in some individuals.

Can tubers be planted in the fall and harvested the next summer like I do with garlic. We usually have a late spring so it's hard to plant until at least June.

I have just received JA`s and want to plant them but we are into the colder months , should i store them and if so how or should i put them in the soil and wait for them to come up ? i dont want to lose these ive been searching for them forever

I would store them in a pot filled with damp sand until spring. If you leave them out they will shrivel and if you plant them they may rot unless you have good drainage. Once established they are virtually indestructible and would survive most winters.

I planted a couple of JA's in spring and about 8 weeks ago they shot up with lovely yellow flowers. I cut these off fairly quickly hoping the growth would go back into the Tubers. I am guessing i could dig some up, but i would like to also move some of the tubers to another spot. Can i do this now or should i wait until the spring?

You could 'raid' a few now if you wanted to. They would be riper when the plants start to die back for the winter. Even though they are just about indestructible it would be better to transplant them in the winter when they are dormant.

I planted Jerusalem Artichoke in February. It is now April and the plants look healthy but have only reached about 1 mtr in height. They reached this height quite quickly but have not moved for about 4 weeks. Is this natural? Thank you.

There could be a number of reasons including; a dry spell, cooler weather, planted late in the season, etc. but if your plants are healthy I don't think you need worry.

Like most of the queries, where can one get JERUSALEM ARTICHOKES? I'm kinda old now but remember my father growing them in Pretoria in the 1950's the goggle eyed face you get when asking at a greengrocer or even a nursery tells all.
