Dear All,
I'm growing Jerusalem artichokes for the first time this year. They seem to
be doing really well, they're about a foot tall and showing no signs of
slowing. What do I need to do to them? Do I need to support the growing
plant with a cane like I would with a sunflower?
No - they're quite sturdy.
Do I earth them up to
improve yield like with spuds?
No
When do I harvest them,
After the plants have died off in autumn. They stay in good condition in
the ground, so it's as easy as anything just to pull a plant or two when
you're ready to eat them. Easier than trying to keep them in good
condition once you've harvested them - they tend to dry out.
If you haven't cooked them before, they're easier to peel after cooking.
The skins just slip off.
and how seriosuly do
I need to worry about them becoming a weed?
The don't spread to any degree, but it's very difficult to clear them
form the ground where you've grown them.
