Propagation by Seed
From Late Spring TO Early Summer
Fill a seed tray with seed compost,water and allow to drain. Sprinkle seeds over the surface allowing roughly 25mm space between seeds and cover with a thin layer of compost. Put tray in a clear polythene bag and place on a windowsill. When seedlings show remove plastic bag. When the second pair of leaves appear on the seedlings thin out to 50mm spacing by removing the weakest looking plants. After 2 or 3 weeks and when danger of frost has passed plants can then be planted outside into required position.
