Getting started
Sow directly where plants will grow; thin seedlings to the spacing needed at maturity.
The right conditions
Choose full sun, fertile free-draining soil and reliable moisture.
As it grows
Water consistently while establishing, keep weeds down and provide support where the mature habit needs it. Watch for local pests and remove damaged growth.
Ready to harvest
Cut the swollen stem while it is still tender, before it becomes woody; the young leaves are also usable.
