Harvest & process

When to cut, how to dry, and how to put a garden plant up. Legal kitchen and medicinal crops only. Restricted plates and poison-garden specimens have no bench here.

Herbs hanging to dry with chamomile on a screen

The bench

Methods

Blossom & seed

Screen-dry flowers

Spread flower heads or seed in a single layer. Turn once. Chamomile, calendula, linden, and rose want shade and air, not a pile. They are done when the center is crisp and the perfume is still there. Rub through a sieve to drop insects and dust.

On the bench

  • A window screen or cloth
  • A dark rack
  • A fine sieve

Not for

  • A wet week with no airflow
  • Sun-bleaching on a dashboard

The day you pick is the day you spread. A bag of damp blossoms is compost.
