Freezing damage poses a serious threat to the healthy growth of tea plants. When tea leaves are damaged by frost, their quality is significantly reduced, and in severe cases, the entire plant may die. To ensure the survival of tea trees through winter and prepare for a bountiful harvest next year, it's essential to implement effective measures to prevent freezing injury.
First, preventing frost damage is crucial. One effective method is to establish windbreaks by planting protective forests on the windward side of the tea plantation. This helps reduce wind speed and minimizes frost damage. Another technique is to mound soil around the base of the tea plants in late autumn, creating a 5–10 cm layer over the roots. This protects the root system and can be removed in spring to improve soil aeration.
Covering the tea garden with grass, weeds, straw, or manure can also help raise the ground temperature. The cover should be applied before winter and removed in early March of the following year. In addition, using smoke from burning dry vegetation on clear, windless nights can create a greenhouse effect, helping to retain heat and protect the plants from extreme cold.
Applying organic fertilizers deeply in the soil not only improves fertility but also increases the plant’s resistance to cold weather. These practices collectively enhance the resilience of tea plants during harsh winters.
If freezing damage has already occurred, prompt recovery measures are necessary. Pruning affected branches and leaves in early spring, once temperatures stabilize, helps the plant recover. After pruning, shallow cultivation combined with a light application of fertilizer, along with watering if conditions allow, can stimulate new growth and restore the health of the tea plants.
By taking these proactive steps, tea growers can minimize the impact of frost and ensure the long-term vitality of their crops.
