Seasons: Winter

The winter weed worth sowing — mineral-rich leaves through the cold months.

A deep trough and forty days is all it asks. Thin ruthlessly for straight roots.

Needs depth more than width — a 30 cm trough of loose soil beats a wide bed.

Roots below, usable leaves above, and it tolerates a container better than carrot.

Quick winter roots for the plains, and greens while you wait.

One good plant in a 40 cm pot out-yields four crowded ones. Stake it early.

A long-season crop that rewards a big pot and steady feeding.

A hill herb of stream banks with aromatic roots and heads of small white flowers.

A dry-hill root used to colour oil a deep red; slight above ground, tough below.

An intensely bitter Himalayan herb of mid-altitude meadows, slow and particular.
