Growing
Cultivating tea as a woody shrub requires a commitment to acidic conditions, as this plant thrives in soil with a pH between 4.5 and 6.0. When you are establishing new plants from cuttings or nursery stock, ensure the site provides excellent drainage to prevent waterlogged roots, though the plant can adapt to full sun or partial shade depending on your local climate. If you are growing in containers, you can easily manage these acidic needs through regular watering and specific soil amendments.
When it comes to harvesting, timing is everything because the leaves do not ripen after they are picked. You should harvest the tender leaves, buds, and stems while they are fresh and ready for use. While you can use the leaves for various types of tea, the stems and twigs can also be harvested to create kukicha. Keep an eye out for caterpillars, such as those from the willow beauty moth, which may attempt to feed on your foliage.
To maintain your harvest, keep the leaves unwashed to prevent premature spoilage. For longer-term use, you can dry the leaves or blanch them before placing them in the freezer. If you have an abundance of seeds, they can actually be pressed to produce a sweetish tea oil, which serves as a unique culinary addition to your kitchen.
