Tea is a beloved beverage in the UK, with an astonishing 165 million cups consumed daily. Despite its popularity, it may come as a surprise that tea can be grown in the UK. This article provides a comprehensive guide to growing tea in the UK, covering everything from climate and soil requirements to harvesting and processing techniques.
Climate and Soil Requirements
Tea plants thrive in subtropical and tropical climates with high rainfall. The UK’s temperate climate poses some challenges, but certain tea varieties have adapted to these conditions. Tea plants prefer acidic, well-drained soil with a pH between 4.5 and 6.5. Ericaceous compost is ideal for growing tea in pots.
Tea Plant Varieties
Two main tea plant varieties are suitable for cultivation in the UK:
- Camellia sinensis (variety sinensis): This variety produces smaller leaves and is more tolerant of cold temperatures.
- Camellia sinensis (variety assamica): This variety produces larger leaves and is less tolerant of cold.
Site Selection and Preparation
Choose a site with partial shade and protection from strong winds. The soil should be well-drained and acidic. Amend the soil with ericaceous compost to improve drainage and acidity.
Planting and Propagation
Tea plants can be propagated from cuttings or seeds. Cuttings are the preferred method as they produce faster results. Plant tea plants in spring or autumn, spacing them 1-2 feet apart.
Care and Maintenance
- Watering: Water tea plants regularly, especially during dry spells.
- Fertilization: Feed tea plants with an ericaceous fertilizer once a year in spring.
- Pruning: Prune tea plants lightly to maintain a manageable size and encourage new growth.
- Pest/Disease Control: Tea plants are generally pest and disease-resistant. However, watch for aphids, scale insects, and fungal diseases.
Harvesting and Processing
- Harvesting: Harvest young leaves from the tips of branches.
- Withering: Spread the leaves in a thin layer and allow them to wilt for 12-24 hours.
- Rolling: Roll the leaves to break down the cell walls and release their flavor.
- Oxidation: Spread the rolled leaves on a tray and allow them to oxidize for 1-3 hours. This process gives tea its characteristic flavor and color.
- Drying: Dry the oxidized leaves in an oven at 110°C for 10-12 minutes until they become crispy.
Challenges and Troubleshooting
- Frost Damage: Protect tea plants from frost by covering them with horticultural fleece or moving them to a sheltered location.
- Inadequate Sunlight: Tea plants require at least 6 hours of sunlight per day. If natural sunlight is insufficient, supplement with artificial lighting.
Tea Production in the UK
The UK has a small but growing tea industry. Tregothnan in Cornwall and The Wee Tea Company in Perthshire are among the pioneers of commercial tea production in the UK.
