Reasons and solutions for yellowing leaves on yew

The yew is a plant unique to China, and it can be grown in both the north and south of the country. High-end bonsai made from it have extremely high ornamental value, but during cultivation, improper operations often cause its leaves to turn yellow. So what should you do when a yew's leaves turn yellow? Here are the solutions.

1. Improper watering

During the cultivation of yew, if it is watered too much, the leaves will become dull and lusterless, and long-term waterlogging may also cause root rot, leading to the death of the yew. And if it is short of water for a long time, the leaves will also dry out and turn yellow due to lack of water.

Solution: When watering, follow the principle of not watering until the soil is dry, and watering thoroughly when you do. If too much water has been applied, loosen the soil to keep it suitably permeable, or directly repot the plant.

2. Unreasonable light

Unreasonable light can also cause the leaves of yew to turn yellow. Leaving it exposed to sunlight for a long time will cause the leaves to lack water and turn yellow and wilt. And when light is lacking, photosynthesis in the leaves weakens, and the roots, because of the lack of leaves, turn yellow and drop.

Solution: If yellow leaves on the yew are caused by too strong light, shade it promptly or move it indoors, then spray water on the leaves and wait for it to gradually recover. In general, place it on a balcony or outdoors in the morning and evening, and move it indoors at noon, so that its light needs can be met.

3. Unsuitable temperature

If the cultivation environment for yew is too hot or too cold, it will have a certain impact on the plant. Too high a temperature will cause the leaves to lack water and become scorched yellow, while too low a temperature will also lead to insufficient nutrition and yellowing.

Solution: When the temperature is too high, find a way to cool it down. You can spray water mist to increase the humidity of the surrounding air and help lower the temperature. When the temperature is low, move the yew indoors and take good cold-proof and warmth-keeping measures.

4. Improper fertilisation

Improper fertilisation also has a great impact on the growth of yew. Too much or too little fertiliser will cause its leaves to turn yellow, and the effect is even greater for newly purchased yews.

Solution: Pay attention to the method when fertilising, and follow the principle of applying thin fertiliser frequently. When the plant has been lacking nutrients for a long time, apply nitrogen, phosphorus and potassium fertiliser in time to ensure sufficient nutrition.
