Caring for Plumeria ‘Royal Hawaiian’

Watering

Water the plant moderately, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so it’s essential to ensure the soil is well-draining.

Fertilizing

Feed the plumeria with a high-phosphorus fertilizer (bloom booster) every 2-3 weeks during the growing season (spring and summer). This encourages vibrant blooms and healthy growth.

Pruning

Prune plumeria in late winter or early spring to shape the plant and remove any dead or damaged branches. Pruning helps promote new growth and flowering.

Pest and Disease Management

  • Pests: Watch for pests like spider mites, aphids, and mealybugs. Treat infestations with insecticidal soap or neem oil.
  • Diseases: Plumeria can be susceptible to fungal infections. Ensure good air circulation and avoid overhead watering to prevent fungal issues.

  3. Plant the Cutting: Insert the callused end into well-draining soil and water lightly.
  4. Provide Proper Conditions: Keep the cutting in a warm, sunny location and water sparingly until roots develop.

Common Issues and Solutions

Yellowing Leaves

Yellowing leaves can indicate overwatering, nutrient deficiencies, or root rot. Check the soil moisture, adjust watering practices, and consider feeding the plant with a balanced fertilizer.
