Care Guide:
Luma plants are easy to care for and require little maintenance once established. Here are some tips to help you care for your Luma plant:

- Fertilization: Fertilize Luma plants in spring with an all-purpose slow-release fertilizer. Repeat every three months during the growing season.
- Soil: Luma plants prefer acidic, well-draining soil. If your soil is alkaline, amend it with peat moss or sulfur to lower the pH.
- Sunlight: Luma plants prefer full sun to partial shade. In hot climates, they may benefit from some afternoon shade.

- Canker: This is a fungal disease that causes sunken, dead areas on the bark. It is caused by poor air circulation and wet conditions. To prevent canker, prune the affected branches and improve air circulation.
