What to Do About Root Rot in Yew? Cause Analysis and Treatment Methods

1. Caused by overwatering

When caring for yew, watering is what requires the most attention. Those who know it well should be aware that it is not a flood-tolerant plant; on the contrary, it is fairly drought-tolerant. If you do not grasp these small points of knowledge, you can easily make the mistake of overwatering it, which makes the potting soil too moist, gradually reducing the oxygen in the pot. At this point, the roots' respiration slows or even stops, switches to a different respiratory mode, and produces alcohol. The roots then rot as a result, and in severe cases, the entire plant can die.

Solution: When watering, try to water thoroughly in one go, and do not keep watering every day. Sometimes some people water based on the condition of the potting soil; when they see the surface of the potting soil is dry, they water immediately. Actually, this is wrong. Sometimes the surface of the potting soil being dry does not mean the inner layer of soil is also dry. In addition, to prevent root rot, you can add a little root-rot prevention agent along with the water, and the concentration of the agent should not be too high; just follow the method of small amounts at a time, multiple times.

2. Caused by using unrotted fertilizer or over-fertilizing

When choosing fertilizer, some people do not pay attention. Sometimes the fertilizer has not been fully rotted before they blindly apply it to the plant, which easily burns its roots and then causes root rot. Or when fertilizing, they do not pay attention to the amount and just keep supplementing nutrients, not realizing that this easily causes excess nutrients in the plant. Once the nutrients are too abundant, the roots cannot absorb them normally, and root rot will also occur.

Solution: When fertilizing, try to choose fully rotted fertilizer, and apply it in small amounts at a time, multiple times.

3. Caused by insufficient light

Although yew is shade-tolerant, if it stays in a dark place for a long time, it cannot carry out normal photosynthesis. This causes a severe lack of nutrients, keeping the roots in a state of starvation, and over time, root rot easily occurs.

Solution: Every few days, we can place it on a balcony or outdoors in the morning or evening to enjoy some light for a while, which can ensure the roots' normal nutritional needs.

4. Caused by underground pests or diseases

In high-temperature and stuffy environments, yew is prone to breeding some diseases or underground pests, which directly affect the roots. Underground pests in particular keep gnawing at the root hairs, causing serious damage and leading to decay.

Solution: Ventilate promptly and cool it down appropriately, while using some insecticide agents to kill the underground pests.
