Okay, so I’ve been growing plumerias for a while now, and let me tell you, it’s mostly sunshine and rainbows. But, like any plant, they can have their issues. I wanted to share my own little journey dealing with plumeria pests and diseases, just in case you’re going through the same thing.
My First Scare: Spider Mites!
Early on, I noticed some tiny, tiny webs on the undersides of my plumeria leaves. And the leaves? They started looking kinda speckled and dull. I squinted, held the leaf up to the light, and yep – tiny little moving dots. Spider mites! I freaked out a little, not gonna lie.

Here’s what I did:
- Blast ’em: First, I took my plumeria outside and gave it a good, strong spray with the garden hose. I made sure to get the undersides of the leaves really well. This knocked off a lot of the mites physically.
- Soapy Water: Then, I mixed up a simple solution of water and a little bit of dish soap. I put it in a spray bottle and sprayed the whole plant, again focusing on the undersides of the leaves. I did this every few days for a couple of weeks.
It worked! The spider mites disappeared, and my plumeria started looking healthy again. I learned my lesson: check those leaves regularly!
The Case of the Yellowing Leaves: Could It Be Rust?
A few months later, another problem popped up. Some of the leaves started getting these weird, yellow-orange spots on them, mostly on the underside. It looked powdery, almost like…well, rust. A quick search online confirmed my suspicions: plumeria rust.
My Rust-Busting Routine:
- Remove and Destroy: First I Cut damaged leaf and throw it.
- Improve Airflow: Ensure enough space for air circulation.
It took a bit of time, but the rust eventually stopped spreading. My plumeria pulled through, a little scarred but still blooming beautifully.

The Chewing Culprits: Caterpillars!
One morning, I went out to admire my plumeria and… gasp! Big, gaping holes in the leaves! It looked like something had been having a feast. And then I saw them – fat, green caterpillars munching away happily.
My Caterpillar Counterattack:
- Pick Them Off:This is help my plumeria keep beautiful.
It was a bit tedious, but it worked. No more caterpillars, no more holes in the leaves. Phew!
So, that’s been my experience with plumeria pests and diseases so far. It’s definitely a learning process, and I’m sure I’ll encounter more challenges down the road. But by staying observant and taking action quickly, I’ve been able to keep my plumerias happy and healthy. I hope my little story helps you with your own plumeria adventures!
