Highly rated by customers for: germination rate
When and how do I plant nasturtium seeds?
Sow the large seeds directly, about ½ inch deep, in full sun after the last frost, spacing them 8 to 12 inches apart. They dislike transplanting, so sow where they will grow. They germinate in 7 to 14 days.
Are nasturtium flowers and leaves edible?
Yes. Both the flowers and young leaves have a bright, peppery flavor like watercress that is great fresh in salads and as a garnish.
Do nasturtiums need rich soil or fertilizer?
No. They bloom best in lean soil that drains well. Skip the fertilizer, which encourages lots of leaves but fewer flowers.
Are nasturtiums annual or perennial?
In most of the US they are grown as annuals, blooming from summer to fall. They often reseed themselves, and you can collect and resow the seeds.
What's the difference between climbing and bush nasturtiums?
Climbing or trailing types spill from pots or climb a trellis, while bush types stay compact for beds and borders. Check the variety for its growth habit.
Are nasturtiums good for kids and pollinators?
Excellent. The big seeds are easy for children to plant, and the flowers draw bees and butterflies while luring aphids away from nearby vegetables.
