Tip Top Alaska series will stay compact so they are perfectly suited to containers. Plant Tip Top Alaska mix Nasturtium seeds in hanging baskets, raised beds, or as companion plants in your organic vegetable garden. These compact Nasturtiums are very bushy, and do not form the long vines found in some other varieties. The foliage is extremely decorative, and the flowers, leaves, and seeds are all edible. Nasturtiums are drought resistant and suitable for xeriscaping.
Sow indoors in peat or coir pots 2-4 weeks before the last frost date. Better yet, direct sow from 1 week after last frost and repeat at 2 week intervals into early summer. Optimal soil temperature for germination: 12-18°C (55-65°F). Seeds will sprout in 7-12 days, perhaps longer outdoors.
Sow seeds 5mm – 1cm (¼”-½”) deep. If starting indoors, provide darkness during germination, followed by bright light. Space smaller varieties 15-30cm (6-12″) apart, and the big ones like Tall Single 60-90cm (24-36″) apart.
Nasturtiums make a good trap crop for aphids, and they deter whiteflies, cucumber beetles, and attract predatory insects. It is a good companion for Brassicas, cucumbers, melons, radishes, and tomatoes.
