Peach Melba Nasturtium Seeds

Don’t start Nasturtium seeds indoors. Instead, direct sow Peach Melba Nasturtium seeds outside after the last frost, once soil has warmed to at least 10°C. Push seeds about 1.5–2 cm into the ground, 20–25 cm apart. Soak seeds overnight before sowing to speed up germination time. Under the right conditions sprouts emerge in 7–14 days.

Nasturtium Peach Melba flowers require full sun — at least 6 hours per day to get flowers. Plants in partial shade put all their energy into leaves and produce almost no blooms. Nasturtiums actually thrive in poor or average soil. Rich, nitrogen-heavy beds push foliage growth and not flowers. Well-draining soil with a pH of 6.0–7.5 is all they need. Water regularly while plants establish, then back off to once or twice a week. 

Deadhead regularly — spent flowers left on the plant signal it to stop producing and start setting seed. One light fertilizer application at planting is enough for the whole season; more than that and you're back to leaves-over-flowers again. Pick flowers in the morning right after they open, when flavor and freshness are at their peak. Young leaves can go into salads throughout summer. If you want to collect seeds for next year, leave a few flowers to mature fully — this is an open-pollinated heirloom nasturtium peach melba variety, so saved seeds will come back true to type every time.
