How to grow nasturtium? A step-by-step guide to the planting method
The nasturtium is not only beautiful in appearance, it also has effects such as clearing heat and detoxifying and protecting the throat, and it can also be eaten as a cold salad. I believe many people want to grow it after seeing its bright flowers, so below the editor will introduce how to grow nasturtium.
1. Growing environment
1. Soil: To grow nasturtium you should use fertile, well-drained sandy soil, which can be prepared using leaf mold, garden soil, sandy soil and compost soil.
2. Light: In spring, autumn and winter, let it receive sufficient light; in summer the light is strong, so shade it in time or let it receive scattered 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 the temperature 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, then sow them in individual spots and cover with 1 cm of soil, and water thoroughly to keep the soil moist. They will sprout in about a week, and 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 cutting, insert it into loose soil, shade it appropriately, and ensure a growing environment of 10-15°C; it will take root in about 15 days.
3. Common pests and diseases
The common pests and diseases of nasturtium include mosaic disease and ringspot disease, aphids, and so on. Once discovered, the diseased branches and leaves should be removed promptly, and pesticides should be sprayed for control. In addition, take care to clear away weeds.
The nasturtium has slightly strict requirements for its environment. Before planting, you can first understand the growth habits of the nasturtium and then cultivate it.
