Growing Jerusalem Artichokes
- How to Grow Jerusalem Artichokes
Jerusalem Artichokes - Fuseau
In 1621 the writer John Goodyer wrote of the Jerusalem Artichoke, “…in
my judgement, which way soever they be drest and eaten they stir up and
cause a filthie loathsome stinking winde with the bodie, thereby causing
the belly to bee much pained and tormented…. more fit for swine, than men.”
This may be a little harsh but the truth is that they can have quite a dramatic
effect, giving them their nick name of 'fartichokes'.
The flavour is described as smoky nuts and honey and they have become quite
a gourmet dish but they are not to everyone's taste. Before growing them it
is as well to try a few meals and see how everyone likes them.
One point that is confusing is the name, Jerusalem Artichokes are nothing
to do with Globe Artichokes. The name comes from a confusion with the Italian
name 'Girasole' or sunflower and the name artichoke comes from the taste being
said to be similar to artichokes. Anyway, Globe and Jerusalem artichokes are
totally different plants.
Cultivating Jerusalem Artichokes
They are grown in the same spot each year, for if you miss a tuber it will
grow like a volunteer potato, so prepare the ground well with plenty of manure
which you can top up as a mulch in winter.
Be careful where you site them, the foliage easily reaches
2 metres and 2.4 metres is common. They stems are quite fragile and you will need to provide
support with stakes and string in windy locations.
Plant individual tubers about 40 to 60cm (15" to 24") apart around 12cm
(4" to 6") deep in early spring and in a few weeks the shoots will appear.
If you have more than one row, allow 75cm (30") between rows. When they
reach about 30cm (12") high, earth up a little as for potatoes.
In the autumn the foliage starts to change colour and should be cut down
to about 30cm (12") above the ground as a marker. You can leave them in
the ground to dig as required. They are quite a productive crop, 3kg from
one plant is typical so you don't need many seed tubers.
Recommended Varieties of
Jerusalem Artichokes
to Grow
The best variety is Fuseau, which is less knobbly and so easier for the cook.
You can save your own tubers to plant in subsequent years but the cances
are that you will have missed one when harvesting that will grow anyway.
You are unlikely to find any other variety on sale although swapped tubers
may be older, more knobbly varieties.
