Best use
The core seasonal Excalibur formula
Excalibur VI is the practical choice for growers whose plumeria have a clear warm growing season and need a balanced controlled-release feed without stretching into a longer release window.
- Best matched to a six-month active growing season.
- Useful for container plumeria and managed collections.
- Designed to provide steady nutrition instead of quick spikes.
- Includes micronutrients and boron for balanced growth support.
Quick choice
Choose VI if your plant wakes in spring, grows through summer, and slows down as the cool season approaches.

Frequently asked questions
Should I use VI or IX?
Use VI for a shorter or clearly seasonal warm period. Use IX when your plants stay active longer and your climate supports a longer release window.
Can I fertilize dormant plumeria?
Wait until plumeria are awake and growing. Fertilizer works best when the plant can actively use the nutrients.
