How to Care for Nasturtium in Winter? A Detailed Guide to Caring for It
To grow nasturtium in winter, you need to take good insulation measures, promptly move the nasturtium indoors to a warm environment for care, and keep the temperature above 8°C so it will not suffer cold damage. You also need to increase light, and it must not be placed in an overly dark environment. Caring for nasturtium in winter also requires reducing the amount of watering, watering once every 7-10 days is enough, and no fertilizing is needed during this period.
How to care for nasturtium in winter
1. Pay attention to insulation
When growing nasturtium in winter, pay attention to taking good insulation measures. The cold tolerance of nasturtium is not very strong, and it can only overwinter safely in an environment above 8°C. Therefore, after the Frost's Descent solar term, it should be moved indoors for care. When the temperature drops sharply, you can wrap it with a layer of plastic film to keep it warm.
2. Increase light
In winter, while keeping it warm, you also need to place the nasturtium in a place with sufficient light for care. If the environment is too dark, it will affect the growth of the nasturtium. When necessary, you can provide artificial supplemental light for the nasturtium so it can get through the winter more healthily.
3. Reduce water and fertilizer
In winter, nasturtium does not need too much watering, and the soil should remain on the drier side. You can water once every 7-10 days, and the water temperature should be similar to room temperature to avoid cold damage. Before winter begins, you can apply one topdressing to the nasturtium to increase its cold resistance, but immediately after winter begins, fertilizing should be stopped.
