How to solve the problem of new leaves of green radish turning black and looking burnt

1. Dilute the fertilizer

Reason: The demand for fertilizer for green radish is not large. Applying too much fertilizer or fertilizer that is too concentrated can easily cause root damage, causing the tips of new leaves to turn black.

Solution: If you have been fertilizing for a long time, you can temporarily stop fertilizing and observe whether there are more serious situations. If the new leaves still turn black, you need to take out the plant, wash it with water, and change the soil and replant it.

2. Keep warm in time

Reason: The low temperature causes the plant to freeze, making it difficult for the roots to absorb water, causing the leaves to turn black.

Solution: The temperature requirement of green radish is relatively high, and it should be kept above 15℃ in winter. If the indoor temperature is not high enough, you can use plastic bags to keep it warm, but remember to ventilate it for a while every day.

3. Provide shade

Reason: The green radish itself likes shade, and long-term exposure to sunlight can easily cause the leaves to turn black, especially in the summer, so avoid strong sunlight.

Solution: Place the potted plants in a place with diffuse light. Strong sunlight in summer requires moderate shade. However, due to differences between the north and the south, the northern green radish needs long periods of sunlight in autumn and winter, which is beneficial for raising the temperature and conducting photosynthesis.

4. Increase humidity

Reason: The air is too dry, which increases the transpiration of the leaves, causing the leaves to turn black after water loss.

Solution: Spray water on the leaves and also sprinkle water on the surrounding ground to increase the air humidity. At the same time, when the temperature is too high, it can be cooled down, which will also help reduce the impact of leaf transpiration.
