Plumeria Bloom Failure: High-Phosphate Fertilizer Solution

Problem

Plumeria produced leaves but no blooms last year while everything else flowered.

Nutrient Imbalance Diagnosis

Excess nitrogen, insufficient phosphate — nitrogen → vegetative growth; phosphate → flowering.

Prescription

• Fertilizer: Green Thumb Blossom Bloom 10-50-10 (high middle number = phosphate)
• Supplement: Epsom salt (magnesium sulfate)
• Mix: 1 tbsp 10-50-10 + 1 tbsp Epsom salt per gallon water
• Frequency: Every 2 weeks during growing season

Principle

High phosphate fertilizers ("bloom boosters") redirect energy from stem/leaf production to flower formation. Epsom salt provides magnesium for chlorophyll and enzyme function.
