Did you know that you can grow your own beverage plants? Coffee’s a challenge in California, but tea gardens are becoming a thing (and not just another fad). You can grow herbs and teas in your flower bed, containers, or even indoors with the right conditions and equipment.
In this blog, we’ll tell you how. Don’t fret if you’re limited on outdoor space. Grab a few pots and plants, pick a sunny spot by a window, and follow our guidelines to start the process.
Camellia Sinensis: the Main Show
Camellia Sinensis is an evergreen shrub whose leaves and leaf buds are the source of tea.
Originating in East Asia, this plant provides the raw material for various teas, including green, black, white, oolong, and pu-erh fermented tea.
The main varieties are Chinese Tea and Assam Tea. Their differences are significant but not enough to classify them as separate species.
Chinese Tea (Camellia Sinensis var. sinensis)
- Thrives in various regions of China.
- The leaves are generally smaller and more delicate than Assam Tea.
- Chinese Tea plants are more resistant to cold temperatures.
- The tea produced from these leaves ranges from light and floral to rich and robust, depending on the processing method.
- These plants tend to have a longer lifespan, with some tea trees living for several hundred years. That’s older than the mayonnaise in your fridge.
- Chinese Tea is the source of many types of tea, including popular variants like green tea, white tea, and lightly fermented oolong tea.
Chinese Tea leaves can be processed in various ways for various flavors.
Assam Tea (Camellia Sinensis var. assamica)
- Assam Tea is primarily grown in the northeastern Assam region of India.
- The leaves are larger and thicker than Chinese Tea.
- Assam Tea plants thrive in warmer climates and high humidity.
- The tea produced from Assam leaves tends to have a malty, robust flavor, often described as full-bodied.
- Assam Tea is predominantly used in making strong black teas, including many breakfast blends.
- These plants are typically more vigorous but have a shorter lifespan than Chinese Tea varieties.
- Assam Tea is a primary component in spiced teas like chai due to its strong flavor profile.
How to Grow Tea Indoors
Soil
- Tea plants prefer slightly acidic soil with a pH between 5.5 and 6.5.
- Use a well-draining potting mix, ideally designed for acid-loving plants like azaleas or camellias.
- Ensure the pot has drainage holes to prevent pooling.
Container
- Choose a 12-inch diameter pot or larger to provide enough room for root growth.
- Consider using a clay or terracotta pot, which allows the soil to breathe and helps regulate moisture.
Light
- Place the pot in a location where it receives at least 6–8 hours of indirect sunlight daily.
- If natural light is low, use a grow light to supplement. We recommend LED grow lights.
Temperature & Humidity
- Tea plants thrive in temperatures between 60-85°F (15-29°C).
- Maintain indoor humidity levels at around 50-70%. You can use a humidifier or place a humidity tray near the plant.
Watering
- Keep the soil moist but not saturated. Water the plant when the top inch of soil feels dry.
- Use room temperature water to avoid shocking the plant roots.
Feeding
- Fertilize your tea plant every 4–6 weeks during the growing season (spring and summer).
- Use a balanced, water-soluble fertilizer or one formulated for acid-loving plants.
Pest & Disease Control
- Watch for common pests like aphids, scale, and spider mites. Treat any infestations immediately.
- Watch for diseases like root rot or powdery mildew. Ensure proper drainage and avoid overwatering to prevent these issues.
Pruning & Maintenance
- Regularly prune the tea plant to promote bushier growth and maintain its shape.
- Remove any dead or yellowing leaves to keep the plant healthy.
Harvesting & Processing
- Tea plants can take 3–4 years to mature.
- Use small scissors or hand pluck the tips of new growth for harvesting.
- Process the leaves according to your desired tea type (e.g., lightly steamed for green tea, fully fermented for black tea).
- Dry the leaves thoroughly before storing or using them.

FAQs: How to Grow an Indoor Tea Garden
Q: How often should I water my indoor tea plants?
That depends on the plants you’re growing, but generally, you should keep the soil moist but not soggy. Water your plants when the top inch of soil feels dry. Check each plant’s needs since some herbs might require more or less frequent watering.
Q: Can I grow tea plants without natural sunlight?
Yes, by using LED grow lights. Place the pots in a location that receives 6-8 hours of light daily, and supplement with grow lights if natural light is lacking. Place the grow lights at an appropriate distance from the plants to prevent overheating and provide the optimal spectrum for photosynthesis.
Q: How do I prevent pests from infesting my indoor tea garden?
Regularly inspect your plants for signs of insects like aphids or spider mites. Use organic insecticidal soap or neem oil to treat any infestations promptly. Ensure proper air circulation and avoid overwatering.
Q: What type of soil is best for growing tea herbs indoors?
Use well-draining potting soil formulated for herbs or indoor plants. The soil should be slightly acidic to neutral for most herb tea plants. Regularly refresh the soil to provide essential nutrients.
Q: Can I grow multiple herbs in the same container?
Yes, if they have similar light, water, and soil requirements. Make sure the container is large enough to accommodate the growth of all the plants and has good drainage.
Q: How do I know when to repot my tea plants?
Repot your tea plants when they outgrow their containers, typically every 1–2 years. Signs that a plant needs repotting include roots growing out of the drainage holes or visibly appearing on the soil surface, drying out more quickly between waterings, or stunted growth.
Q: Is growing an indoor tea garden in a small apartment possible?
With the right containers, well-draining soil, and adequate light (natural or supplemented with LED grow lights), you can grow an indoor tea garden even in a mousehole apartment. Consider vertical gardening or using shelves to maximize space.
Q: How should I harvest and store my herbs for the best flavor?
Harvest herbs in the morning. Use sharp scissors or pruners to snip the leaves or flowers. Store fresh herbs in a cool, dry place, or dry them by hanging bundles in a well-ventilated area away from direct sunlight. Once dried, store herbs in airtight containers to retain their potency.
