Care Guide

💧 Water Every 3-5 days
Suggested frequency: Every 3-5 days
☀️ Light Full sun

The fukien tea tree grows best with abundant sunlight. This hardy plant can also tolerate spots with moderate light. However, too much direct sun can burn the leaves, and too little light can limit its growth. Native to areas that receive plenty of sunshine, it does well in comparable lighting conditions.

Ideal: Full sun
🌡️ Temperature 20–37.8°C

The fukien tea tree comes from tropical and subtropical regions where temperatures range from 68 to 100.4 ℉ (20 to 38 ℃). This temperate woody plant favors a warm, humid environment, with daytime temperatures of 70 to 80 ℉ (21 to 27 ℃) and nighttime temperatures of 55 to 65 ℉ (13 to 18 ℃). During hot summer months, it’s best to move the plant so it remains between 68 and 85 ℉ (20 to 29 ℃).

Ideal temperature: 20–37.8°C
💨 Humidity normal (40-60%)

This plant will thrive in moderate humidity, which is probably the level in your home. However, misting it a few times a week can be very beneficial. Make sure the room has good ventilation.

Humidity: normal (40-60%)
🪴 Soil 6-7
Soil pH: 6-7
🌱 Fertilizer

Fertilizing is essential for the care of the Fukien tea tree. Regular applications during the growing season preserve the energy needed for its showy foliage and encourage overall growth. Failure to fertilize can lead to unhealthy leaves, reduced ornamental value, and stunted or fragile growth that is susceptible to breaking.

🪴 Pot & Repot 2-3 years

When repotting a Fukien tea tree, choose a pot 1-2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits slightly below the rim of the flower pot. Water thoroughly after repotting and place in a warm spot with indirect sunlight.

Suggested frequency: 2-3 years
✂️ Pruning

The Fukien Tea tree does not require extensive pruning as the leaves are naturally small and may retain its shape for a long period of time. Pruning is, however, not detrimental but beneficial to the plant. Use a sharp pruner to trim young shoots that have developed 6-8 leaves and also cut mature branches off. When pruning the shoots, ensure to leave at least two or three leaves to avoid damage to your tree. It is great to do this throughout the year as required.

☠️ Toxicity

Although the Fukien Tea is edible and is used in the Philippines as a herbal remedy to treat some stomach disorders and coughs, the leaves of the tree can be mildly toxic to humans and pets(dogs, cats) if ingested in excessive quantities, causing irritation to the stomach and oral cavity. It is best to keep them out of reach of inquisitive children and household pets, and contact a veterinarian if you notice symptoms of irritation after excessive consumption.
