FAQ
Is Sunn Hemp the same as cannabis hemp?
No. Sunn hemp is Crotalaria juncea, a legume cover crop. It is not Cannabis and is sold here for garden cover-crop use.
When should I sow Sunn Hemp?
Sow after frost when soil is warm and active growth can continue through the warm season. It performs best in full sun.
Should I let it make seed?
For cover crop use, many gardeners mow or cut before mature seed set so the planting contributes biomass without becoming hard to manage.
