When it comes to growing tea in cold climates, the China type (Camellia sinensis var. sinensis) is your best bet. These tea plants are known for their cold tolerance and can withstand lower temperatures compared to the Assamica type (Camellia sinensis var. assamica).
China type tea plants are well-suited for regions that experience frost and can thrive in cooler temperatures. They are a great option for gardeners in areas with a colder climate, as long as the temperatures do not drop too low. However, it’s important to note that extreme cold can still damage or even kill these plants, so some protection may be necessary during harsh winter conditions.
On the other hand, the Assamica type tea plants are not suitable for cold climates. They are native to the warmer and more humid regions of Assam, India, and are not frost-tolerant. These plants require a consistently warm and wet environment to thrive, making them better suited for areas with a tropical or subtropical climate, typically found in Plant Hardiness Zone 10b and above.
In my personal experience, I have successfully grown China type tea plants in my garden, even in a region with relatively cold winters. By providing some winter protection, such as mulching around the base of the plant and covering it with a frost cloth during extreme cold spells, I have been able to keep the tea plants healthy and productive.
If you are looking to grow tea in a cold climate, the China type (Camellia sinensis var. sinensis) is the recommended choice. These cold-tolerant tea plants can withstand lower temperatures compared to the Assamica type (Camellia sinensis var. assamica), which is better suited for warmer and more humid regions. However, it’s important to provide some winter protection to ensure the health and survival of the tea plants in colder climates.
