How to Seed Nasturtium Tom Thumb ‘Black Velvet’ (Tropaeolum majus nanum)

1. When to Sow: Sow directly outdoors in spring to early summer after the last frost, or indoors 3–4 weeks earlier for earlier blooms.

2. Soil: Thrives in poor to moderately fertile, well-drained soil. Avoid overly rich soil, as it encourages leaves rather than flowers.

3. Sowing: Sow seeds 2 cm deep, spacing them 25–30 cm apart.

4. Watering: Water lightly but regularly. Do not overwater, as nasturtiums prefer slightly drier soil once established.

5. Germination: Seeds sprout in 10–14 days at 15–20 °C.

6. Thinning/Transplanting: If sown thickly, thin seedlings to allow good airflow and spacing. Nasturtiums dislike root disturbance, so sow in place whenever possible.

7. Care: Place in full sun for best flowering. Deadhead faded blooms to prolong flowering.
