How to Use Excalibur Boost for Safe, Short-Term Feeding of Plumeria
Excalibur Boost is the fast-acting companion to Excalibur VI and IX slow-release fertilizers. Designed specifically for plumeria, Boost delivers a short-term nutrient top-up that’s safe, effective, and low in salt, making it ideal for mid-season corrections, early growth support, or supplementing tired soil.
This guide explains what Excalibur Boost is, how it compares to VI and IX, and when and how to apply it for optimal root and bloom response.
What Is Excalibur Boost?
Excalibur Boost is a quick-release fertilizer formulated with the same core NPK balance (11-11-14) and micronutrient profile as Excalibur VI and IX—but in a form that begins breaking down immediately upon application.
| Feature | Value |
|---|---|
| Type | Quick-release granules |
| NPK Ratio | 11-11-14 |
| Micronutrients | Yes (chelated) |
| Release Time | 2–3 months |
| Salt Index | Low |
| Usage Form | Granular topdress or mix-in |
When to Use Excalibur Boost
| Situation | Why Boost Helps |
|---|---|
| Spring Jumpstart | Supports early-season root and leaf flush before slow-release kicks in |
| Mid-Season Top-Up | Recharges nutrient levels in pots with high rainfall or leaching |
| Post-flush Feeding | Boosts energy for flower production or new leaf growth |
| After Soil Flushing | Reintroduces nutrients after salt buildup or leaching |
| Short-cycle containers | Perfect for cuttings or seedlings not yet on full VI/IX schedule |
✅ Safe for use in bark-based, pine-based, and perlite mixes
How to Apply Excalibur Boost
For Containers:
- Rate: 1 tablespoon per gallon of container size
- Method: Sprinkle evenly across the soil surface (not against the stem)
- Water in lightly to begin activation
- Reapply after 8–10 weeks, if needed
For In-Ground Plumeria:
- Rate: ¼ to ½ cup per mature tree
- Apply in a ring around the drip line, not at the base
- Water well and monitor during the blooming phase
Tip: Use Boost during periods of active growth or just before bud formation for best flowering support.
Comparison with Excalibur VI and IX
| Feature | Excalibur Boost | Excalibur VI | Excalibur IX |
|---|---|---|---|
| Release Time | 2–3 months | 6 months | 9 months |
| Purpose | Fast correction, top-up | Seasonal feeding | Annual or long-term feeding |
| Best For | Mid-season boost, flushing recovery | Containers, seedlings, small pots | In-ground, large pots, low-maintenance growers |
| Fertilizer Salt Risk | Low | Low | Low |
Tips for Success
- Do not mix with high-phosphorus bloom boosters—the NPK is already balanced
- Ideal pairing with mycorrhizae, biochar, or microbial teas
- Avoid applying if the soil is wet, compacted, or anaerobic—flush first
- Combine with foliar feeding in early spring if leaf chlorosis is present
- Apply to actively growing plants only—never use on dormant plumeria
When to Avoid or Delay Use
| Condition | Why to Wait |
|---|---|
| Dormant plumeria | Nutrients won’t be absorbed |
| Saturated soil | Risk of root rot |
| Immediately after rooting cuttings | Wait until active leaves and roots are visible |
| If Excalibur VI or IX was just applied | Avoid overfeeding—Boost is supplemental, not primary |
Conclusion
Excalibur Boost is a reliable, plumeria-specific tool for correcting nutrient dips and stimulating mid-season performance. It provides a fast-acting, low-risk top-up to your fertilization routine, especially when timed with active growth or post-flushing recovery.
Used alongside Excalibur VI or IX, Boost ensures your plumeria get exactly what they need when they need it—without stressing the roots or overloading the soil.
