The Excalibur story
Built because plumeria needed better answers
Excalibur exists for growers who want a plumeria-first feeding system instead of adapting general-purpose fertilizers to a very specific tropical plant.
The problem
Plumeria growers needed dependable seasonal nutrition without constant guesswork, fertilizer spikes, or formulas made for unrelated plants.
The answer
Excalibur organizes controlled-release fertilizer choices around plant stage and growing-season length.
The next step
Choose BOOST, VI, or IX based on what the plant is doing now and how long your warm season lasts.
