- Toxicity
To humans
The most common common name of Camellia sinensis var. sinensis is "tea plant". The tea plant is not considered toxic to humans when consumed in typical beverage quantities. In fact, it is widely consumed around the world in the form of green tea, black tea, and oolong tea. However, consuming large amounts of tea leaves might lead to caffeine-related side effects due to the caffeine content in the leaves, including restlessness, insomnia, headaches, dizziness, irregular heartbeats, and in severe cases, caffeine intoxication. Chronic overconsumption may lead to caffeine overdose with symptoms such as agitation, tremors, stomach upset, and disorientation.
To pets
The most common common name of Camellia sinensis var. sinensis is "tea plant". The tea plant contains caffeine and is therefore potentially toxic to pets, including dogs and cats, if they consume a significant quantity of the leaves. Symptoms of tea plant poisoning in pets can include vomiting, diarrhea, hyperactivity, tremors, increased heart rate, seizures, and in severe cases, collapse or death. Pet owners should ensure their animals do not have access to tea leaves or brewed tea to prevent caffeine toxicity.

- Water
Tea plants require consistent moisture and should be watered every week with 1-2 gallons of water, depending on the size of the plant and the climate. During dry spells, increase watering to twice a week. It's crucial to water the base of the plant without wetting the leaves to prevent fungal diseases. Allow the top inch of soil to dry out between watering to encourage deep root growth. Overwatering can lead to root rot, so be cautious not to let the plant sit in waterlogged soil.
- Light
Tea plants prefer bright, indirect light with protection from the hot afternoon sun. A location with morning sunlight and dappled shade in the afternoon is ideal for the tea plant. Ensure the plant receives at least a few hours of sunlight daily to maintain healthy growth but avoid exposure to intense midday rays which can damage the foliage.
- Temperature
Tea plants thrive in a temperature range of 65-85°F and can tolerate minimum temperatures down to around 30°F for brief periods. Optimal growth occurs in the warmer end of this spectrum, and it's essential to protect the plant from frost, which can severely damage or kill it. The ideal conditions for a tea plant include a consistent, mild climate without extreme temperature fluctuations.
- Pruning
Prune tea plants annually to maintain health and shape, typically in late winter or early spring before new growth starts. Remove dead or damaged branches, thin out any crowded areas to improve air circulation, and trim back to encourage bushy growth and more tea leaves. Severe pruning isn't necessary unless the plant has become overgrown.
- Cleaning
As needed
- Soil
Tea plant, commonly known as Camellia sinensis, thrives best in slightly acidic soil with a pH of 6.0 to 6.5. A good soil mix consists of equal parts of ericaceous compost and pine bark with some perlite for improved drainage and aeration.
- Repotting
Tea plants, Camellia sinensis, should be repotted approximately every 2-3 years or when they become root-bound in their container, to ensure continued growth and health.
- Humidity & Misting
Camellia sinensis, generally known as the tea plant, prefers high humidity levels, ideally between 70% and 90%, to mimic its native tropical and subtropical growing conditions.
- Suitable locations
Indoor
Keep Camellia sinensis in bright, indirect light; water well.
Outdoor
Plant Camellia sinensis in partial shade and shelter from wind.
Hardiness zone
7-9 USDA
- Life cycle
The life of the tea plant (Camellia sinensis var. sinensis) begins with seed germination, typically in a nursery bed, where it develops a strong root system and foliage. After 1-3 years, the young tea plant is transplanted to a tea garden where it matures over several years before it reaches a suitable size for commercial harvesting. During the vegetative stage, the plant grows continuously, producing new shoots which, after reaching a certain maturity, are plucked for tea production. The reproductive stage starts with the tea plant flowering, usually after it is three years old, although flowers are rarely allowed to bloom fully as priority is given to leaf harvesting. If the flowers are pollinated, they develop into fruit with seeds, which can be collected and sown to propagate new plants. The tea plant can remain productive for over 30 to 50 years, after which yield and quality can decline, leading to replanting.
- Propogation
Propogation time
Spring to early summer
Propogation: The most popular method for propagating the tea plant, Camellia sinensis var. sinensis, is through semi-hardwood cuttings. This is typically done from late summer to early autumn, when the plant has matured but the wood is not yet completely hardened. A 4 to 6-inch cutting is taken from the current year's growth, and the leaves on the lower half are removed. The cut end is then dipped in rooting hormone to enhance root development and placed in a well-draining soil mix. This cutting should be kept under high humidity conditions and out of direct sunlight to encourage root growth. It can take several weeks to a few months for the cutting to root successfully.
