🌿 Why Fertilizer Choice Matters

Plumeria need the right balance of nutrients to produce vibrant flowers, strong branches, and healthy roots. Two standard fertilizer options used by plumeria growers are:

• Excalibur – a slow-release granular fertilizer
• BR-61 – a high-phosphorus, water-soluble bloom booster

Each serves a specific purpose, and using the right one at the right time makes a big difference, especially for beginners.

🔍 What Is Excalibur?

Excalibur Fertilizer is a slow-release granular fertilizer specially developed for plumeria. It comes in several formulas:

Product	Release Time	Best Use Case
Excalibur VI	6 months	Container plants, spring feeding
Excalibur IX	9 months	In-ground plants, once-a-season
Excalibur Boost	2–3 months	Short-term boost or late-season pots

✅ Excalibur Pros:

• Long-lasting—apply once per season
• Balanced nutrients plus micronutrients
• Gentle on roots (won’t burn)
• Reduces salt buildup
• Feeds evenly based on temperature and moisture

🧪 Best for overall plant health, consistent growth, and natural blooming.

🔍 What Is BR-61?

BR-61 is a water-soluble, high-phosphorus bloom booster with a typical NPK of 9-58-8.

✅ BR-61 Pros:

• Promotes fast bloom initiation
• Can trigger flowers in mature plants
• Useful if the plant is growing but not blooming

❌ BR-61 Cons:

• Too much phosphorus can lock out other nutrients
• Easily overused—can damage roots or cause salt buildup
• Must be reapplied regularly (every 2–4 weeks)

⚠️ Use BR-61 sparingly and only when plumeria are actively growing and well-rooted.

⚖️ Side-by-Side Comparison

Feature	Excalibur	BR-61
Type	Slow-release granular	Water-soluble liquid
Application Frequency	Once per season	Every 2–4 weeks
Nutrient Focus	Balanced (NPK + micronutrients)	Very high phosphorus (P)
Risk of Overuse	Low	High
Encourages Growth	Yes	No (focuses on blooming only)
Encourages Blooming	Yes, steadily	Yes, often quickly (but can be short-lived)
Best For	All-around growth, low maintenance	Bloom pushes during the active season

🧾 Beginner Recommendation

✅ Use Excalibur as your main fertilizer, especially in spring.
🔁 Use BR-61 optionally once at the beginning of bloom season (late spring or early summer) for mature, rooted plants only.

💡 Think of Excalibur as your daily nutrition plan, and BR-61 as a single energy shot—useful, but not sustainable on its own.

---

🛑 Avoid These Common Mistakes

• ❌ Using BR-61 on unrooted or stressed plants
• ❌ Fertilizing with BR-61 every week
• ❌ Skipping base nutrients and relying only on bloom boosters
• ❌ Applying BR-61 during cool spring temps or dormancy

🌺 Conclusion

For beginners, Excalibur is the safest and most effective all-in-one fertilizer for consistently feeding plumeria throughout the season. BR-61 can help promote blooms, but it should be used sparingly and never as the main fertilizer. With the right balance, your plumeria will grow stronger and bloom longer, without the risk of overfeeding.
