Frequently Asked Questions

What pest or disease most often affects Tropaeolum majus (whirlybird nasturtium), and how do I control it?

A common issue is aphids clustering on new growth and flower buds, especially in warm weather. Spray the plant with a strong jet of water to knock them off, then follow with insecticidal soap or neem labeled for edible flowers, repeating every 5–7 days until colonies stop. Also watch for powdery mildew; improve airflow by spacing plants and avoid wetting the leaves when watering.

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

Water regularly to keep the top 1–2 inches of soil lightly moist, but don’t keep the bed soggy—nasturtiums perform best with even moisture rather than constant wetness. In full sun and warm weather, this usually means watering about 1–2 times per week, increasing frequency only if the soil dries out quickly. Reduce watering once plants are established if leaves look lush but growth is not flowering, since overly wet soil can drive leafiness.

How can I tell when Tropaeolum majus is ready to harvest?

Start harvesting once plants are established and producing flowers (often around 50 days), choosing blooms in the morning for best flavor and firmness. Harvest leaves and tender shoots when they’re young and before they turn thick and fibrous, and pick frequently to encourage more flowering. If you’re harvesting seeds, wait until seed pods are plump and turning papery on the plant before collecting.

Whirlybird Cream unfurls with a luminous, creamy-gold bloom that seems to whirl in the sun—delicate petals with a soft, warm glow and a gentle, peppery lift. The foliage is tender and succulent, forming a lush, trailing mound that stays attractive as it flowers, offering crisp, fresh leaves with a bright, slightly peppery character. Grow it for standout garden color and for elegant garnishes that turn salads, platters, and herb-forward dishes into living bouquets.

Sowing Tips

Transplant Conditions

Wait until soil reaches 55°F and nights stay above 40°F before moving outdoors.

Expert Note

Sow nasturtium seeds directly where you want them (or plant outdoors as soil warms), because they resent root disturbance and flower best with steady sun.
