Q.My medinilla magnifica’s leaves are starting to have some dry brown spots and fall off.
The plant is about five years old. We have had it for three years and it continues to bloom year around. Now some of the leaves are getting dry brown areas and are fall off easily if touched. How to I stop this and get the plant back to health.
Thank you

These two articles will help you address the issues, and keep the plant healthy. I also would consider repotting into a slightly larger pot.
