Pruning timing

Spring

March - April

Spring cleanup Remove old stems from previous year close to the ground before new growth starts.

Summer

June - August

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.
