Growing it

Propagation
seed
When to plant
Spring
Overwintering
This plant is typically grown as an annual and will die back with the first frost. You can collect seeds in late autumn to sow again the following spring.
In containers
It grows well in containers, provided you use a pot at least 30 centimeters in diameter to support its large root system.

Seed

  1. 1. Surface sow the tiny seeds in a seed starting tray.
  2. 2. Keep the soil moist and in a warm, bright location.
  3. 3. Transplant seedlings once they have two sets of true leaves.

Planting aromatic herbs nearby can help confuse pests looking for the large, soft leaves.

Grows well with

  • Marigold — They help deter soil nematodes that can affect the roots.
  • Basil — The strong scent of basil can help mask the plant from certain pests.

Keep away from

  • Tomato — They share similar pests and diseases which can spread rapidly between them.
