Cultivation methods and precautions of knotweed

1. Watering

In spring and autumn, just keep the soil in the pot slightly moist when watering. In summer, when the temperature is high, the water evaporates quickly, so you can water more often. The best time to water is in the morning or afternoon when the sunlight is not very strong. In the cold winter weather, the plant grows very slowly, so try to water it as little as possible to prevent frost damage and waterlogging.

2. Soil

In terms of soil selection, in order to better cultivate its fleshy roots, it is best to choose sandy loam for cultivation. At the same time, the drainage performance of this soil is also very good, which can greatly reduce the possibility of root rot caused by water accumulation.

3. Fertilization

During the growing season, in order to ensure that it can better differentiate flower buds, phosphorus-potassium compound fertilizer should be applied once in early autumn. After flowering, nitrogen fertilizer is generally used as the main fertilizer, and the focus at this time is on growing branches and leaves. Ensure it has the nutrients it needs for growth, and try not to fertilize at other times.

4. Lighting

When cultivating it, you should place it in a sunny place for maintenance. Pay attention to shade in summer to prevent sunburn. If its leaves turn yellow, it is likely caused by excessive light. In winter, as long as there is enough light and the temperature is suitable indoors, it will be fine.

5. Notes

When raising plants indoors in winter, pay attention to ventilation. If the air is not circulating, pests and diseases are likely to occur. When watering it, be careful not to allow water to accumulate. Waterlogging can cause root rot and leaves to fall off, seriously affecting next year's flowering.
