Why Excalibur
Designed around how plumeria actually grow
Excalibur uses controlled-release nutrient technology to feed gradually when moisture and warm growing conditions are present. The line is built around plumeria culture, with micronutrients and boron included for balanced plant development.
- Controlled release avoids the spike-and-crash pattern of quick liquid feeding.
- Formulas are matched to real grower use cases: establishment, six-month feeding, and nine-month feeding.
- Florida Colors Nursery uses plumeria-growing experience as the practical test bed.
Use with confidence
A simple feeding workflow
1. Feed active plants
Apply Excalibur when plumeria are awake, warm, and actively growing. Dormant plants cannot use fertilizer efficiently.
2. Match the formula
Use BOOST for establishment, VI for a shorter season, and IX where the warm season is longer.
3. Follow the label
Use the current product label and Florida Colors purchase page for bag sizes, rates, and availability.
