How to Apply Excalibur Plumeria Fertilizer
Apply Excalibur when the plant is awake, warm, rooted, and actively growing. Then place the fertilizer where roots can use it, keep it away from the trunk, cover or blend it lightly with soil, and water it in.

Before you feed
Make sure the plant can use fertilizer
Warm and active
Feed during active growth, not while the plant is cold, dormant, or stalled. Fertilizer works best when roots are taking up water and the plant is building leaves, stems, or blooms.
Rooted and stable
A rootless cutting, a severely stressed plant, or a plant sitting wet should be stabilized first. Feeding should support growth, not force a plant that is not ready.
Right formula
Use BOOST for establishment or recovery, VI for a six-month feeding window, and IX for longer warm-season growing conditions.
Basic method
Application steps
Check the current label
Use the current Florida Colors product page and the physical product label for the amount to apply. Rates can vary by formula, container size, plant size, and current label guidance.
Place it around the root zone
Distribute the granules around the soil surface near the active root zone. Keep fertilizer away from direct contact with the trunk or stem.
Cover lightly and water in
Lightly cover the granules with soil when practical, or blend them into the upper soil layer. Water thoroughly after application so the controlled-release coating can begin working with moisture and warmth.
Do not pile fertilizer against the trunk. A light, even placement around the root zone is safer than a concentrated clump in one spot.
BOOST as a side dressing
Use BOOST when extra support is actually needed
BOOST can be used for newly rooted plants, grafts, transplants, repotting recovery, or a mid-season support decision. For an established seasonal plan, VI or IX usually acts as the base fertilizer and BOOST is used only when the plant has a reason for extra support.
- Apply BOOST away from the trunk, near the active root area.
- For containers, a small hole near the outer root zone can help place the fertilizer below the surface.
- Do not stack repeated fertilizer applications simply because blooms are slow. First check light, temperature, roots, water, and maturity.

Container and in-ground notes
| Growing situation | Best application habit | Watch for |
|---|---|---|
| Container plumeria | Apply around the outer root zone and water in well. Containers dry and flush differently, so avoid repeated stacking of fertilizer. | Salt buildup, poor drainage, fertilizer against the stem, or feeding a plant that is still root-limited. |
| In-ground plumeria | Spread evenly around the active root area rather than at the trunk. Water in if rainfall is not reliable. | Very dry soil, heavy rain patterns, competing roots, mulch piled against the trunk, and seasonal dormancy. |
| Newly rooted or repotted plants | Use restraint. BOOST may help when roots are present and the plant is ready to resume growth. | Rootless cuttings, transplant shock, wet soil, soft stems, or cold conditions. |
When not to apply
Dormant or cold plants
If the plant is not actively growing, fertilizer may sit unused and create stress instead of progress.
Rootless cuttings
Wait until roots are forming and the plant is able to take up water. Fertilizer cannot replace root development.
Wet or stressed roots
If roots are struggling from overwatering, rot risk, or poor drainage, correct the root-zone problem before adding nutrition.

Application amounts
Estimate the amount by container size, trunk diameter, number of branches, and overall tree size.
Water and root health
Watering and fertilizer work together. Use the watering guide when drainage, dry-down, or root-zone moisture may be the real issue.
Seasonal and regional care
Timing changes by climate. Use seasonal guidance before deciding whether a plant is ready for feeding.
Cultivation and planting
Use this when potting, repotting, soil mix, drainage, or transplant stress affects feeding decisions.

Bottom line
Apply Excalibur with the plant’s readiness in mind: active growth first, correct formula second, careful placement third, and water-in after application. When in doubt, pause and diagnose before adding more fertilizer.
