Frequently Asked Questions

What pest or disease commonly affects Tropaeolum majus (Peach Melba), and how can I control it?

A common issue for Tropaeolum majus is aphids clustering on tender new growth, especially in warm weather. Rinse plants with a firm stream of water, then spray insecticidal soap (or a neem-based insecticide) in the early morning and repeat every 5–7 days if aphids persist. Watch for sooty growth and leaf distortion, and remove heavily infested tips to reduce reinfestation.

How often should I water Tropaeolum majus during active growth?

Keep the soil evenly moist during germination and early establishment, but avoid standing water—Tropaeolum majus prefers well-drained soil. After plants are established, water when the top 1 inch of soil feels dry, typically about once or twice per week depending on heat and wind. Water at the soil line rather than overhead to reduce leaf wetness and disease risk.

How do I know when Peach Melba (Tropaeolum majus) is ready to harvest?

For seed harvest (about ~50 days), pick when pods turn brown and feel dry, then snip and let them finish drying indoors. If you’re harvesting flowers, begin picking when blooms are fully open and vibrant—harvest frequently to encourage more flowering through the season. Avoid harvesting everything at once; stagger picks every few days so the plant keeps producing.

Sun-warmed, peachy-orange blossoms with a creamy blush at the throat unfurl in a profusion that feels almost perfumed—delicate, peppery-sweet notes with a bright, tangy snap. “Peach Melba” nasturtium forms tender, succulent leaves and crisp, jewel-like flowers that hold their color beautifully in the garden, offering a vivid accent from early summer through the 50-day peak. Grow it for its show-stopping blooms and their lively, distinctive flavor in fresh garnishes, salads, and vibrant pickling-style preparations.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 40°F before moving outdoors.

Expert Note

For the best blooms, sow directly after frost danger passes and avoid transplanting—nasturtiums establish best from seed and resent root disturbance.
