Light
Cinnamon trees need bright, direct light, so place them less than a foot from away from a south-facing or western window. They don't tolerate low light. In the summer, you can bring the plant outside to boost its growth, but you may need to keep it in a sheltered area to avoid scorching the leaves. When transitioning the plant from indoors to outdoors, give the leaves a few days to adjust to the brighter conditions.
