How to Grow Nasturtiums from Seed
The seeds can be planted indoors 4-6 weeks before late spring frost in Australia. The plants can be planted outdoors in early spring in partly shaded areas or in full sun in well drained soil. Planting nasturtiums in rich, fertile soil can cause lush foliage growth, but fewer flowers. The seeds should be planted a half inch deep in the beds providing 10-12 inches spacing. The seeds will germinate within 7-10 days. Plant the seeds in spring when the frost conditions are over. Nick the seeds with needle and soaking the seeds overnight in lukewarm water causes faster germination. Providing trellis in the planting area help the plant to climb easily.
