Winter Tea Garden Sealing Is Timely for Tea Trees
With the drop in temperature, it's time to perform winter sealing of tea gardens.
Which tea gardens should undergo winter sealing? Tea gardens that have experienced severe infestations of pests such as tea Orange spider mites, scale insects (including Unaspis citri, Unaspis stevensi, and Unaspis yanonensis), black scale insects, and tea anthracnose can benefit from winter sealing. This helps control pest and disease outbreaks in the following year, reducing the number of pesticide applications and ensuring the safety of tea quality.
Sealing Time: The most suitable period is when the daily average temperature is between 10-15°C. If the temperature is too high, there is a risk of causing leaf fall due to phytotoxicity. If it's too low, the expected results may not be achieved.
Sealing Agent: We recommend using lime-sulfur solution. A dilution of 45% crystalline lime-sulfur solution at 150-200 times its concentration.
Precautions: Thoroughly spray the entire Tree, including both sides of the leaves, branches, and the base of the bushes, akin to giving the tea trees a complete cleansing and disinfection.
Special Reminder: Lime-sulfur solution is strongly alkaline and must not be mixed with other pesticides.
In late October to early November this year, temperatures were unusually high, causing some West Lake Longjing tea trees that had been pruned earlier to sprout autumn buds, which could affect the sprouting of Spring Tea next year. With temperatures now dropping, tea trees will enter their dormant phase. For tea gardens where autumn buds have already sprouted, it's best to arrange for workers to remove these immature autumn buds to promote the development of winter buds.
