Frequently Asked Questions

What pest or disease most commonly affects Tropaeolum majus (Jewel Mix), and how can I treat it?

Nasturtiums (Tropaeolum majus) are prone to aphids, which cluster on new growth and can distort leaves and buds. Spray aphids off with a strong jet of water, then repeat every 2–3 days for a week; if pressure is heavy, use insecticidal soap according to the label and target the undersides of leaves. Avoid overhead watering to reduce leaf spotting and keep air moving around plants.

How often should I water Tropaeolum majus during peak growth?

During active flowering and leaf growth, keep soil evenly moist but not soggy—water when the top 1 inch of soil feels dry. Aim for deep watering that wets the root zone, then let excess drain; consistently wet soil encourages stem rot in nasturtiums.

How do I know when Tropaeolum majus (Jewel Mix) is ready to harvest?

You can start harvesting around day 45, but pick as soon as flowers are fully open for best color and flavor. Harvest leaves and young stems after plants are well established (typically once they have several true leaves), before they turn tougher. For seed harvest, wait until the seeds develop and the pods dry on the plant.

A jewel-bright cascade of blooms and tender leaves, Jewel Mix bursts with peppery, garden-fresh flavor that feels vivid and alive. Expect a lively mix of colors—sunlit oranges, warm reds, and creamy yellows—paired with crisp, succulent texture that holds its snap from garden to bowl. Grow it for striking edible flowers and flavorful foliage in salads, garnishes, and quick pickling, or let the trailing plants spill over containers and beds for nonstop color.

Sowing Tips

Transplant Conditions

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

Expert Note

Sow nasturtium where you’ll grow it; richer soil increases leaves at the expense of blooms.
