The Plumeria Fertilizer and Nutrition Guide offers comprehensive advice on how to properly feed plumeria to achieve optimal growth and vibrant blooms. This guide covers the critical aspects of plumeria nutrition, including how to select the right fertilizers based on your plant’s specific needs, balance essential nutrients like nitrogen, phosphorus, and potassium, and manage soil pH to enhance nutrient uptake. It also explores the use of supplements and soil additives to support sustained health and vitality, ensuring your plumeria remains strong and healthy throughout the year. Whether you’re aiming to boost growth during the active season or enhance blooming, this guide provides the essential information to tailor your fertilization practices for the best results.

Excalibur Fertilizer Comparison Guide (with Dosage Recommendations)
Overview
Excalibur fertilizers are specially formulated for plumeria, offering three blends—IX, VI, and Boost—designed for long-term, seasonal, and short-term use. Each formula is slow-release, with a low salt index and full support for healthy growth and blooming. Here’s how they compare by nutrient analysis, release duration, micronutrient profile, use cases, and how much to apply.
1. Release Duration
| Formula | Release Duration | Ideal Application Time |
|---|---|---|
| IX | 9 months | Early spring, once per season |
| VI | 6 months | Early or mid-season top-dress |
| Boost | 2–3 months | Pre-bloom, post-prune, or recovery boost |
2. Nutrient Analysis (N-P-K)
| Formula | Nitrogen (N) | Phosphorus (P) | Potassium (K) |
|---|---|---|---|
| IX | 11% | 11% | 14% |
| VI | 11% | 11% | 13% |
| Boost | 10% | 12% | 14% |
3. Micronutrient Content
| Formula | Chelated Micronutrients | Notes |
|---|---|---|
| IX | Yes (full spectrum) | Long-term uptake; ideal for in-ground trees |
| VI | Yes (essential profile) | Balanced for container/top-up use |
| Boost | Yes (non-chelated) | Designed for short-term support |
4. Best Use Cases
| Formula | When to Use |
|---|---|
| VI (6-month release) | Season-long feeding for in-ground or large container plumeria |
| VI (6 month release) | Seasonal top-up for containers or as a supplement to IX |
| IX (9-month release) | Stimulating blooms, helping recovery, or supporting growth after pruning |
5. 📏 Recommended Dosage Guidelines
These are general dosage guidelines—adjust slightly based on soil quality, age of the plant, and regional climate.
| Container Size / Tree Type | IX (9 mo) | VI (6 mo) | Boost (2–3 mo) |
|---|---|---|---|
| 1–3 gal pot | 1–2 tablespoons | 1–2 tablespoons | 1 tablespoon |
| 5–7 gal pot | 2–3 tablespoons | 2–3 tablespoons | 1.5–2 tablespoons |
| 10–15 gal pot | 1/4 cup | 1/4 cup | 2 tablespoons |
| 20+ gal / large containers | 1/3–1/2 cup | 1/3–1/2 cup | 1/4 cup |
| In-ground mature plumeria | 1/2–1 cup (once) | 1/3–1/2 cup | 1/4–1/3 cup |
Application tips:
- Apply evenly around the root zone—not directly on the stem.
- Water deeply after application to initiate slow-release activity.
- Do not exceed recommended doses; more is not better.
- Avoid applying to dry roots; always water before feeding.
6. Suggested Application Timing
- Excalibur IX: Apply once at the start of the growing season (late winter/early spring).
- Excalibur VI: Use early or mid-season, especially in container-grown plumeria or as a second feeding.
- Excalibur Boost: Apply every 6–10 weeks during active blooming or stress recovery, especially after pruning or transplanting.
Summary
- Excalibur IX: For long-term, season-wide feeding in-ground or in-container.
- Excalibur VI: For mid-season top-dressing for in-ground or in-container feeding.
- Excalibur Boost: For short-term enhancement and flower stimulation.
Using these formulas strategically supports your plumeria through all growth phases. This approach requires fewer applications and lessens the risk of salt buildup.
Final Takeaway
Each Excalibur formula supports plumeria at distinct growth stages:
- Start the season with IX for stable, lasting nutrition.
- In mid-season or shorter climate zones, use with VI.
- When flowers are forming or plants need a boost, apply Boost.
Using them intentionally, rather than over-applying a single formula, delivers healthier, more abundant plumeria blooms.
