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 vs. BR-61: Which Fertilizer Should You Use for Plumeria?
Excalibur vs. BR-61: Which Fertilizer Should You Use for Plumeria?
Both Excalibur and BR-61 are popular among plumeria growers, but they serve different roles. Whether you’re seeking steady growth, improved bloom cycles, or both, this comparison will help you understand which fertilizer to use—and how to combine them safely for maximum effect.
Nutrient Breakdown
| Fertilizer | NPK Ratio | Type | Micronutrients |
|---|---|---|---|
| Excalibur VI/IX | 11-11-14 or 11-11-13 | Slow-release (granular) | Full chelated micros (Fe, Mn, Zn, Cu, Mo, B) |
| BR-61 | 9-58-8 | Water-soluble (quick release) | Includes Fe, Mn, Zn (likely chelated) |
- Excalibur provides balanced, long-term nutrition ideal for root development, foliage, and foundational support.
- BR-61 delivers a bloom-focused phosphorus boost and is used to trigger or enhance flowering.
Release Method & Duration
| Fertilizer | Release Mechanism | Duration | Application Frequency |
|---|---|---|---|
| Excalibur | Osmosis-based (moisture activated) | 6–9 months | Once or twice per season |
| BR-61 | Water-soluble, instant | Few days | Weekly or biweekly as needed |
When to Use Each
| Goal | Best Product | Why |
|---|---|---|
| Season-long feeding | Excalibur VI or IX | Osmosis-based slow release supports consistent growth |
| Quick bloom initiation | BR-61 | High phosphorus triggers flower development |
| Low-maintenance care | Excalibur | Apply once; feed for the season |
| Supplemental flowering | BR-61 | Use at bloom stage only |
Can You Use Excalibur and BR‑61 Together?
Yes—and doing so strategically can maximize both vegetative growth and bloom response. The key is spacing out applications and understanding their roles.
✅ Suggested Feeding Strategy: Excalibur + BR‑61 Combo
Step 1: Apply Excalibur in Early Spring
- Use VI or IX for long-term nutrition
- Provides a balanced base with chelated micronutrients
- Feeds consistently for 6–9 months
Step 2: Introduce BR‑61 During Pre-Bloom Stage
- Begin when buds are visible or plants are entering the flowering phase
- Apply every 10–14 days as a soil drench or foliar spray
- Limit to 2–4 applications per cycle
Step 3: Monitor and Flush if Needed
- BR‑61 is strong—flush containers lightly every few weeks if using repeatedly
- Avoid combining with other high-phosphorus products simultaneously
Timing Chart: Dual Fertilizer Plan
| Growth Stage | Excalibur Use | BR‑61 Use |
|---|---|---|
| Early Spring | Apply once | Not yet needed |
| Pre-Bloom (Mid Spring) | Ongoing release | Start BR‑61 every 10–14 days |
| Peak Bloom | Active | Continue if needed |
| Post-Bloom | Still feeding | Discontinue to avoid stress |
| Early Fall | Taper off | Do not use |
Application Tips
Excalibur:
- Apply to moist soil early in the season
- Use 2 tbsp per inch of trunk diameter
- Water in thoroughly
BR‑61:
- Mix ~1–2 tbsp per gallon of water
- Apply as a foliar spray or soil drench
- Avoid use during intense heat or drought
✅ Pros & Cons Comparison
| Fertilizer | Pros | Cons |
|---|---|---|
| Excalibur | Long-lasting, low-burn, full micro support | Not bloom-specific; slower visible response |
| BR-61 | Immediate flowering support, flexible use | High salt potential requires careful timing and limited uses |
✅ Conclusion: Best of Both Worlds
For many plumeria growers, the ideal feeding system is not either/or—but Excalibur + BR‑61 used together with purpose.
- Start the season with Excalibur to establish a strong foundation and maintain healthy roots and foliage.
- As bloom season approaches, use BR‑61 to push flowering without relying solely on nitrogen-heavy blends.
- Used correctly, this combo delivers consistent growth and eye-catching blooms, with minimal risk and effort.
