Growing Plumeria is comparatively easier for us as it can perform well without intense care. But as the humidity and temperature increase, Plumeria faces a lot of issues. Since I began growing and caring for Plumeria, I've been learning how to overcome the challenges that come with it. One of the major problems is white spots on Plumeria leaves. In this article, I will let you know the exact reasons for white spots on plumeria leaves and how to treat them.
Mostly it happens due to spider mites, but I will share a picture so that you can get an idea if it is due to spider mites or not.
What type of white spots have I noticed on my Plumeria leaves?
In my case, the plumeria leaves were full of white dotted spots. Tiny white rounded dots all over the leaves.
I have taken a picture of an infected leaf. I have zoomed the picture and cropped it so that you can take a closer look.
Before jumping to the cure, we must need to identify the disease first. In my case, the white spots were due to spider mites. But in your case, it might be something else. If you find a similarity between your plumera leaves and mine then it must be spider mites. If your plant is infected with spider mites you can also notice curling leaves.
If you notice powder-type substances and the spots are larger then that might be powdery mildew. But on plumeria there is less chance to have powdery mildew.
The solution: curing white spots
If you can confirm those are spider mites then here's what you need to do:
Spider mites can reproduce must faster than you can even imagine. When I first sensed their presence, it took around 1 week only to spread all over my plumeria plant.
- First spray water with a good blast to dislodge mites. (This is not necessary but I do this) Do not try this on young and new plants.
- Use insecticidal soap or neem oil to kill any remaining mites.
- You can bring ladybugs on your plants and they will help you to reduce the spider mites. ( This is the only natural way, which can not be done by most of us)
If it is due to powdery mildew then there is a natural home remedy for it. Use baking soda (1 tablespoon per gallon of water) and spray it on the affected leaves.
If you leave your plant untreated then it can cause leaves yellowing and brown spots as well.
Maintain proper watering to make your plumeria healthy. You can check my full watering guide for Plumeria.
Tip: Do not forget to check the bottom side of your plumeria leaves. If you find anything unusual let me know in the comment section below.
