Insufficient lightingTaxus is a light-loving plant. If it is kept in an environment with insufficient lighting for a long time, it will lead to yellowing leaves. This is because insufficient lighting affects the process of photosynthesis, which in turn leads to malnutrition of the leaves.2. Improper wateringWatering is a crucial aspect of Taxus maintenance. If the amount of watering is excessive or insufficient, it can lead to yellowing leaves. Excessive watering can cause waterlogging at the roots, affecting root respiration, while insufficient watering will make the soil dry, causing the leaves to lack water.3. Soil problemsSoil is the foundation for the growth of Taxus. If the soil pH is not suitable, compacted, or lacks nutrients, it can lead to yellowing leaves. The suitable soil pH value is between 5.5-6.5, with good drainage and rich in organic matter.4.
