Flowering Season
From Early Summer TO Early Autumn
Orange or yellow flowers appear from early Summer to early Autumn
Planting
From Mid Spring TO Late Spring
Sow seeds 3/4 of an inch deep in mid to late Spring at the flowering site
Propagating
From Early Spring TO Mid Spring
Nasturtiums self-seed very readily, and flowers allowed to go to seed will drop seed that will grow readily the following Spring. Can also be sown in seed trays - 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.
