How to Grow Nasturtium? Detailed Planting Methods and Care Tips

Nasturtium flowers are very eye-catching in color, mostly yellow or orange-red. It is an annual or perennial climbing succulent herb, with the whole plant smooth and hairless. So, how do you grow nasturtium?

1. Growing environment

1. Soil: To grow nasturtium, you should use fertile, well-drained sandy soil. You can mix leaf mold, garden soil, sand, and compost for use.

2. Light: In spring, autumn, and winter, let it receive plenty of light. In summer, when the light is strong, shade it promptly or let it receive indirect light.

3. Temperature: Give it a growing environment of 18-24°C. It can tolerate 0°C for a short time. In summer, the temperature should not be higher than 35°C; if it is too high, it will stop growing. In winter, keep the temperature above 10°C.

2. Propagation methods

1. Seed propagation: Sowing can be done in March-April or in September-October. Before sowing, soak the seeds in warm water for one day. After sowing in spots, cover with 1 cm of soil and water thoroughly to keep the soil moist. They will sprout in about a week. When 2-3 true leaves have grown, pot them up.

2. Cutting propagation: Cuttings are generally taken in spring and autumn. Remove the lower leaves of the cuttings, insert them into loose soil, provide appropriate shade, and ensure a growing environment of 10-15°C. They will root in about 15 days.

3. Common pests and diseases

Common pests and diseases of nasturtium include mosaic disease and ringspot disease, aphids, and so on. After discovery, promptly remove the diseased branches and leaves, and spray with chemicals for control. In addition, be careful to clear away weeds.

Because nasturtium is not cold-tolerant and likes warmth and moisture, in winter you must take good cold protection measures for it.
