The temperature will become very low in winter, and the plant's demand for fertilizer is not high at this time. As long as it is not particularly short of fertilizer, there is no need to fertilize it. But fertilizing once before winter can help it survive the winter. If the fertilizer is applied too thickly, the leaves will fall off, and some water will need to be poured to promote the discharge of fertilizer. If there is no way to drain it, the plant needs to be removed and the roots replaced with soil.

1. Is it possible to fertilize?

After winter, the temperature will gradually drop. In a low-temperature environment, the rhododendron will grow slowly or temporarily stop growing. Therefore, the demand for fertilizer is not high at this time, so as long as it is not particularly short of fertilizer, there is no need to fertilize it in winter. But before winter, you only need to fertilize it once. If you continue to fertilize in winter, the leaves will easily wither or turn yellow, so you cannot fertilize it.

2. What happens when leaves fall?

Rhododendron likes fertilizer, but does not like heavy or concentrated fertilizer. If the concentration of fertilizer is too high, its root system will be burned. Once the roots of the plant rot, they will no longer be able to deliver nutrients and water to the leaves, and the leaves will fall off over time.

If leaves fall off, stop temporarily Fertilize. Then pour more water into the soil, and the fertilizer in the soil will be discharged with the water, and then place it in a place with good air circulation. If the fertilizer cannot be discharged, the plant must be taken out and the original soil replaced. If the roots are rotten, prune them appropriately, but disinfect them before potting.

3. Precautions

When fertilizing rhododendrons, use thin fertilizer. Do not apply fertilizers with too high a concentration, and do not apply too much fertilizer, nor do you fertilize too frequently. Generally, fertilizing once every 10 days or so during the growing season is sufficient.
