The Beauty of Plumeria (Frangipani)

Originating from Central America, the Plumeria tree, also known as the lei flower plant, has traveled across continents. Its mesmerizing fragrance and vibrant blooms make it a favorite among gardeners. Often, it’s the star of tropical gardens!

Plumerias, while lovely, are susceptible to various pests and diseases. Deformed plumeria leaves, black tip fungus plumeria, and other plumeria leaf problems can arise from these threats. While some pests, like mealybugs on plumeria, cause plumeria leaves to fall off, this guide is tailored to address the notorious plumeria spider mites.

Getting to Know Spider Mites

All About Spider Mites: Tiny Thieves of Beauty Spider mites aren’t spiders, even if their name suggests so! They’re tinier and belong to the arachnid family, just like spiders, but that’s where most similarities end. A spider mite’s life begins as an egg, growing into a larva, then becoming a nymph, and finally, an adult. This entire cycle can happen in as little as a week!

To spot them, look for small white spiders on plants or their signature white webbing. It’s different from the usual spider web, more like a thin white veil over plumeria leaves. But they’re not just about webs. They suck out the plant’s nutrients, leaving tiny yellow dots, called honeydew, which can make the plant weak and sickly over time.

These are not your average spiders; they are much smaller and can cause tiny yellow dots on leaves. Unlike ordinary spiders, spider mite web versus spider web is different. The mite’s webbing looks like white webbing on the plant, different from the classic cobweb.

Treating Plumeria Spider Mites: Your Action Plan

  1. Inspect: Regularly check your plumeria. The sooner you spot spider mites, the better.
  2. Spray Time: Mix water and alcohol (like rubbing alcohol) in a spray bottle. Mix 1 part rubbing alcohol (70% Isopropyl Alcohol) to 4 parts water. For example, 2 ounces of alcohol mixed with 8 ounces of water.
  3. Fill a spray bottle. Gently mist the entire plant, especially the underside of the leaves. Be sure to mist the whole plant including the stems, flowers and leaves. (
  4. Repeat: One spray might not do the trick. It’s best to spray every few days for a couple of weeks to ensure you’ve gotten all the mites, especially since new ones might hatch.
  5. Keep Monitoring: Even after they’re gone, stay vigilant! Spider mites are sneaky.

If you don’t want to mix the homemade alcohol spray treatment, Bayer BioAdvance 3-1 is a great option that also protects against other insects and fungal infections.

Expert Tips for A Mite-Free Garden

  1. Stay Clean: Regularly clean the area around your plumeria. Debris can be a breeding ground for pests.
  2. Natural Predators: Ladybugs love munching on spider mites! Consider introducing a few to your garden as natural defenders.
  3. Water Wisely: Misting your plants occasionally can deter spider mites, as they prefer dry conditions.
  4. Check and Double-Check: Regularly inspect your plants, especially if they’ve had mites before. Keep an eye out for signs of plumeria leaf stress like puckering or curling.
  5. Be on the lookout for Ants on Plumeria, ants can be a sign of other pests. Ants like to eat the honeydew (yellow dots or secretions left by spider mites).

Conclusion: Embrace the journey of gardening and protect your plumeria from its tiny foes. With a keen eye and proper care, your plumeria can flourish, free from the grip of plumeria spider mites!
