Directions: If grown under cover when the first two true leaves appear harden the seedlings off by taking them outside on a cool cloudy day. Keep watered. When the seedlings are 6-8cm tall plant in the garden. First remove the seed leaves (cotyledons) and plant up to the first set of true leaves. Water in.
