Frequently Asked Questions

What pest or disease problem affects Tropaeolum majus (Jewel/Dwarf Cherry Rose Jewel), and how can I control it?

Nasturtiums (Tropaeolum majus) commonly get aphids, especially on new shoots and flower buds; blast them off with a strong jet of water and repeat every 2–3 days for a week. If you see gray, fuzzy growth on leaves, improve airflow and avoid wetting foliage—remove badly affected leaves and water at the soil line instead. For severe aphid outbreaks, spot-spray with insecticidal soap, targeting the underside of leaves early in the morning.

How often should I water Tropaeolum majus during its main growing phase?

During active growth and until the plants are established, water when the top 1 inch of soil feels dry, then water thoroughly so moisture reaches the root zone. In hot weather, this may be about every 2–4 days, but reduce frequency if the soil stays moist or rainfall is regular. Avoid consistently soggy soil because Tropaeolum majus dislikes waterlogged conditions and can develop leaf issues.

How do I tell when Dwarf Cherry Rose Jewel (Tropaeolum majus) is ready to harvest?

Harvest flowers at about 35 days from sowing: pick blooms when they have fully colored petals and the buds are just about to open. For leaf harvest, take young, tender leaves that are bright green and not heavily aged, typically after the plant has started flowering. Stop harvesting leaves if flowering slows—keep picking flowers to maintain production.

Fragrant, jewel-bright blooms—rose-pink to warm cherry-red with velvety petals—rise above a compact mound, releasing a peppery perfume that feels both vivid and alive. Dwarf Cherry Rose Jewel forms tender, crisp leaves and succulent seed pods with a lively, tangy bite, perfect for adding color and zing to fresh arrangements and garnishes. Grow it for its quick 35-day payoff and its nonstop show: a compact nasturtium that delivers beauty first, with flavor that follows at every glance.

Sowing Tips

Transplant Conditions

Wait until soil reaches 50°F and nights stay above 40°F before moving outdoors.

Expert Note

Sow nasturtium directly after frost danger passes (warm soil) for the best success—roots resent transplanting.
