Grow Your Own Tea Plant

By Kelly Miller

Even though tea is the world’s second-most-consumed beverage, tea plants aren’t common in American gardens. However, throughout the Southeast and even in cooler regions, with extra care, you can grow your own tea plant.

Tea plants take a few years to produce harvests. Once they do, it’s incredibly rewarding to brew your daily “cuppa” with homegrown leaves. Here’s all you need to know to decide if a tea plant deserves a spot in your home garden.

Types of Tea Plants

Camellia sinensis, or tea plant, is an evergreen shrub or small tree, native to East Asia. The leaves, buds, and stems of Camellia sinensis are used to make tea.

Parts of many other plants, such as mint leaves or ginger roots, can be steeped to make hot beverages. However, “true tea” comes only from Camellia sinensis.

There are two main varieties of Camellia sinensis that are most popular for tea and either one can be cultivated to grow your own tea plant at home:

One variety is Camellia sinensis var. sinensis, known as “China type” or “Chinese tea plant”. These plants originated in China and are mainly grown in East Asia. They have small leaves.

The other popular variety is Camellia sinensis var. assamica, known as “Assam tea plant”. This type originated in Assam, a state in India. Assam tea leaves are larger.

Both varieties of Camellia sinensis can make all types of tea (green, black, white, or oolong), although Assam tea leaves are most often used for black teas. Different types of tea are produced by using different methods to dry and process the leaves.

The Difference Between White, Green, Black and Oolong Tea

Understanding the differences between green, white, and black tea starts with an exploration of what part of the tea plant is used for green tea, white tea, and black tea. All three teas originate from the same plant – Camellia sinensis – but it’s the age of the leaves and their processing that sets them apart.

White tea uses only the youngest shoots, the unopened buds and sometimes new leaves which are simply dried with minimal processing. This results in a subtle flavor profile often described as light and sweet. White tea typically has the lowest caffeine level among the different teas.

For green tea, young leaves are harvested before they fully mature. These leaves are quickly steamed or pan-fired to prevent oxidation, preserving their vibrant color and delicate flavor. Green tea has more caffeine than white tea.

Black tea comes from older, mature leaves that undergo a full oxidation process after harvesting. This gives black tea its characteristic dark color and robust flavor. If you’re looking for a pick-me-up, black tea typically has the highest level of caffeine.

Oolong tea is a traditional Chinese tea made from the partially oxidized leaves. Oolong tea falls somewhere between green and black tea in terms of oxidation and flavor. It is known for its unique taste, which can range from floral and fruity to rich and toasty, depending on how it’s processed. Oolong tea contains less caffeine than black tea but more than green tea.

So while all teas come from Camellia sinensis, it’s their unique combination of leaf maturity and handling that creates such distinct aromas, colors, and tastes in your cup.

Where Can You Grow Tea Plants in North America?

Camellia sinensis likes lots of sun and water, so it’s mainly grown in tropical climates. The world’s top tea-producing nations are China, Kenya, India, and Sri Lanka.

In the US, tea plants grow best in USDA Zones 7–9, but can also grow in the hottest zones (10–11), or in slightly cooler regions. The best growing conditions are found in Hawaii and the Southeast, especially the Carolinas, Georgia, Alabama, and Mississippi. If you are a gardener living in these regions, you should find it easy to grow your own tea plants.

When growing tea in cooler climates (Zone 6), Camellia sinensis var. sinensis is the best option, offering better cold tolerance than Camellia sinensis var. assamica.

Planting and Caring for Tea Plants

Attempting to grow your own tea plant from seed can be tricky. Even if you are successful, waiting for your plant to grow may result in at least two years of waiting for your first harvest. Thus, most gardeners purchase young starter plants that have already completed a year of growth and have well-developed root systems.

Plant Camellia sinensis in spring or fall in full sun or part shade. Tea plants are tolerant of various soils. Their ideal medium is well-draining soil that’s sandy and slightly acidic, with a pH around 5.5 or 6.0.

Water regularly, whenever the top inch of soil has dried. Add fresh compost to the soil every fall, and provide occasional doses of balanced fertilizer throughout the growing season.

If they’re left alone, tea plants will grow into trees. However, they’re typically trimmed to maintain a size of 3–5 feet (0.9–1.5m). When tea plants are kept small, they’re easier to harvest from and produce a greater volume of foliage. 

Can You Grow Your Own Tea Plant in a Container?

If you live in a cooler zone, you can still successfully grow your own tea plant. Growing a tea plant in a container is a good option if you live in a region that experiences freezing winters. During winter, the pot can be brought indoors for protection against harsh winds and freezing temperatures.

A potted tea plant should have a container that’s at least twice as wide and deep as the root ball. To reach a mature size, the plant will eventually require a very large pot. Potted tea plants should also be fertilized more often (at least twice per year) than plants grown in the ground.

Pruning, Harvesting, and Processing Tea

A tea plant begins producing harvestable leaves after two or three years of growth. Only the tender, young leaves and buds are used for making tea. Regular pruning helps the plant devote more of its energy toward new growth, resulting in stronger harvests.

Tea plants bloom in fall or winter. Prune in late winter or early spring, after the blooming season. Cut back growth to reduce the plant’s total size and remove dead or damaged branches.

A tea plant harvest may last throughout the summer. The recommended method for collecting tea leaves is to pluck off “two leaves and a bud.” This refers to harvesting sets of two young, tender leaves, along with the single bud that grows alongside them. Harvesting these parts at the right moment produces the best-quality tea. Continuously harvesting young leaves also encourages the plant to keep producing new growth throughout the summer.

After harvest, processing begins. Processing involves drying the leaves, crushing or rolling them, then “fixing” the product at the desired moisture level. Processing is an art form that varies widely depending on which type of tea is desired. If you want to learn more about tea leaf processing, visit this guide from JusTea.

Plant an Herbal Tea Garden

If you want garden-fresh tea, a tea plant isn’t your only option. Teas made from herbs may not be “true teas,” but they’re still wonderful. Learn how to grow your own herbal tea ingredients in this guide: Plant a Tea Garden.
