🌱 How to Care for Fukien tea tree to Prevent Scale Insects?

💧 How to Water

Check the top 1–2 cm of soil with your finger: if dry, water thoroughly until water drains from the bottom of the pot, then allow the top layer to dry again before the next watering. This may mean daily watering in summer or every 3–5 days in cooler months—do not let the root ball dry out completely or sit in stagnant water.

☀️ Lighting

Place in a bright east or west window where it receives plenty of indirect light with some direct morning sun; protect from full midday summer sun as the leaves can scorch. In low light conditions, shoots will become leggy, foliage will thin out, and flowering will cease.

🪴 Ideal Soil

A loose, well-draining, airy bonsai soil mix is ideal, such as a combination of akadama, lava rock or pumice, and a small amount of aged organic matter—compact, water-retentive garden soil will lead to root rot.
