🌿 Short Answer:
Start fertilizing in spring when your plumeria shows signs of waking up, and continue through mid-summer. Stop feeding by early fall to allow your plant to slow down naturally before dormancy.
📅 Fertilizing Timeline by Season
| Season | What to Do | Notes |
|---|---|---|
| Late Winter–Early Spring | Wait until growth begins (buds swelling, new leaves) | Don’t fertilize dormant plants |
| Spring (March–May) | Apply slow-release fertilizer (e.g., Excalibur VI or IX) | Start feeding once plant is active |
| Summer (June–August) | Continue regular feeding; optional Excalibur Boost mid-season | Stop bloom boosters by late July |
| Fall (September–October) | Stop all fertilizer by mid to late fall | Prepares plant for dormancy |
| Winter | Do not fertilize dormant plants | Resume in spring after signs of growth |
✅ Signs It’s Time to Start Fertilizing
- Buds at branch tips are swelling
- New leaves begin to emerge
- Soil is drying faster (indicates root activity)
- Temperatures are consistently above 60°F (16°C)

⚠️ When Not to Fertilize
- ❌ While the plant is dormant (no leaves, no active growth)
- ❌ When soil is cold or wet
- ❌ Just after repotting (wait 1–2 weeks)
- ❌ Before a cold front or frost risk in fall
- ❌ On unrooted cuttings or newly pruned branches
🧰 Tips for Fertilizing Success
- Water lightly after applying slow-release fertilizer
- Use a balanced formula with micronutrients for best growth
- Do not overfertilize—excess salts can burn roots
- Supplement with foliar sprays (kelp, fish emulsion) only during active growth
- Avoid high-phosphorus formulas unless used once at bloom initiation
