Reasons for dried-up leaves on yew (Taxus) and how to fix them
1. Caused by water
Yew is very afraid of dampness. If too much water remains on the plant when watering, or if the potting soil is too wet, it is very easy for the roots to lack oxygen. The roots' respiration will be severely restricted, ultimately causing the roots to begin to rot and making the leaves dry up.
Solution: When watering it, it is best to water thoroughly all at once, and then wait until the potting soil is dry before watering again. In addition, when watering, you can also combine it with some medication for treating root rot. When applying the medication, the amount must not be large, and the concentration must not be too high. By applying it in small amounts more frequently, its roots can grow normally, and the leaves will no longer dry up.
2. Caused by light
Yew is relatively shade-tolerant, but in order to make it grow better, you should still give it an appropriate amount of sunlight. If there is not enough light, nutrients will also be severely lacking, causing the leaves to begin to dry up.
Solution: It is shade-tolerant and afraid of strong light, so you can place it on the balcony or in the yard in the morning and evening, but it must not be placed there every day. It is best to leave a gap of a few days in between, and then the leaves will immediately return to normal.
3. Caused by a small pot and a large seedling
When it was first planted in the pot, it was still a small plant, so the pot chosen was also relatively small. But as time went on, the plant gradually grew larger, and the roots needed more nutrients, resulting in insufficient nutrients in the potting soil and the space inside the pot becoming cramped. Once the nutrient supply cannot keep up, the roots are likely to die, so the leaves also begin to dry up.
Solution: In the morning or evening when the weather is cooler, repot it with fresh potting soil. When repotting, the small holes at the bottom of the larger pot should be raised appropriately, and the bottom layer is best supported with a small stone to facilitate drainage. When choosing potting soil, use humus soil as much as possible, and then add some iron-containing preparation, so as to supply iron to the leaves over the long term and prevent the leaves from drying up.
4. Caused by a lack of nutrients
During care, if the potting soil has not been loosened for a long time, and combined with frequent watering, the soil eventually becomes compacted and no longer breathable, and nutrients decrease accordingly, so the leaves begin to dry up.
Solution: You can add an appropriate amount of organic fertilizer to the potting soil, applying it together with loosening the soil, and then water. In addition, you should also fertilize its leaves. The best time to fertilize is around 5 pm, so that the nutrients will be sufficient, and the leaves will also become dried up.
