Cultivation methods and precautions of yew

1. Soil

The pH value of the soil required by yew is between 5.5-7.0. Loose, moist, well-drained, fertile acidic sandy soil with high organic matter content is the best. You can mix garden soil, peat soil, and sandy soil together, and add a small amount of decomposed organic fertilizer.

2. Lighting

Yew likes shade and needs proper shading to avoid direct sunlight to prevent water evaporation, which will cause the branches and leaves to become dehydrated and the leaves to dry out. It should be placed indoors in the summer and on the windowsill in the evening for ventilation. Although yew does not like sunlight, it cannot live without it. In climates where the sunlight is not strong, it can receive appropriate amounts of sunlight.

3. Watering

The yew tree needs more watering during the growing season and less watering during the dormant period. Specifically, water it once every 5-7 days in spring and autumn, once every 3-5 days in summer, and once every 7-10 days in winter. At the same time, it also depends on the actual growth conditions. Generally, normal yew leaves are upright and shiny. If you find that the leaves are wilted, you need to water them; if the leaves droop, it means that the water shortage is very serious and you need to water them; if you find that the sound is very hollow when knocking on the flowerpot, you also need to water them.

4. Fertilization

When growing yew trees, it is necessary to fertilize them in time, using 0.2 catties of organic fertilizer and 0.02 catties of compound fertilizer for each plant. At the same time, you can also add some farmyard manure, cake fertilizer, etc.

5. Temperature

Yew prefers a cool and humid climate environment and can withstand temperatures as low as minus 30°C. The most suitable growth temperature is 20-25°C. It does not require excessive warming measures in winter, and pays attention to shading when the temperature is too high in summer.

6. Disease and Pest Prevention

Under normal growing conditions, yew trees rarely have insect pests. If they become yellow or have insect pests, water or spray them with methyl mopshrine or potassium dihydrogen phosphate. During the rainy season, yew trees will suffer from root rot, stem rot and root rot, which should be prevented with dichlorvos. In hot and dry seasons, yew trees are prone to leaf blight and red blight, which should be controlled by spraying with Bordeaux mixture.
