Watering - Water plumeria thoroughly just before the soil dries out. During colder months, when the plants are dormant, you can stop watering completely.
Fertilizer - Fertilize every two to three weeks during peak growing season (March to August) with Tiger Bloom by Foxfarm or a Bloom Special fertilizer. You can also supplement with Super Phosphate to help keep a compact size and increase blooms on your plumeria.
Pruning - Prune damaged branches off of your plumeria immediately, or if you wish to control the size, prune branches right where they meet the main trunk.
Pests - You may occasionally see insects such as spider mites, whiteflies or mealybugs on your plumeria. An organic insecticide such as Neem Oil or Captain Jack’s Deadbug Brew will treat these insects.
Preventing Disease - Plumeria rust is the most common disease of plumeria and appears as an orange powder accompanied by blisters on the leaves. Treat with Thiomoyl or Liquid Systemic Fungicide.
