Pruning timing
Spring
Spring cleanup Remove old stems from previous year close to the ground before new growth starts.
Summer
Vitalization pruning Removing flower stalks encourages the formation of new, tender leaves.
Remove
- Dead aerial parts in late winter
- Flower stalks (unless seed saving is desired)
- Old, tough leaves during the season
Preserve
- Rootstock (rhizome)
- Young heart leaves
- Emerging buds at the base
Avoid
- Damaging the fleshy taproot during hoeing
- Complete clearing of the bed before winter (frost protection)
Tools and hygiene
Use clean knives to prevent rot on the fleshy rootstock.
