To keep your Plumeria healthy, it’s important to watch out for caterpillars and leaf-eating insects. Check your plant often for signs of damage, and if you spot any caterpillars, try to remove them by hand if there aren’t too many. For more serious infestations, you can use insecticidal soap or neem oil. To prevent future outbreaks, try to attract natural predators like birds and other helpful insects. Finally, if any parts of the plant are heavily infested, make sure to prune and dispose of them to keep the rest of the plant healthy. By taking these steps, you can help protect your Plumeria from harm and keep it looking its best.
