After trying every fertilizer you can think of and searching for Fertilizers specifically formulated for Plumeria and not finding anything worth using, we decided we had to have a professional company custom mix a fertilizer. We knew from years of experience that Plumeria do best when you feed them a balanced fertilizer that provides nutrients as Plumeria need them. We believe that healthier plants will result in better growing habits and more blooms.
So to create the best possible fertilizer for Plumeria, we needed to have one formulated to our specifications just for Plumeria. The fertilizer had to have a balance of needed nutrients, but also had to have a dependable slow release rate for the entire growing season. We wanted to market nationwide so we choose Harrell’s Fertilizers, one of the largest fertilizer companies in the US. After many years of experimenting and research we came up with a slow released 11-11-13 poly cote with micronutrients that lasts 9-12 months. The release rate was formulated to release the nutrients as Plumeria needs them over the growing season. The formula is activated by moisture and heat, but mostly by moisture. Releasing more when you water more, minimizes the release rate during dry months and dormancy.
Excalibur IX and Excalibur VI is a Florida Colors Nursery exclusive custom mixed fertilizer that’s been formulated specifically for Plumeria. The ingredients are formulated to provide your plumeria with the nutrients it needs to thrive. The poly cote has been formulated to release the nutrients when plumeria need it most.
A slow release fertilizer designed to be used once and last 6 for Excalibur VI or 9 months for Excalibur XI. We produced two different fertilizers to match the different growing seasons. For example Texas and Florida would use 9 month and areas with shorter growing seasons would us 6 month.

How to use Excalibur IX and Excalibur VI
Excalibur is a slow release water soluble granular fertilizer, it is applied dry and must be watered in. It help to improve efficiency by covering the granules with 1/2″-1″ of soil. Granular fertilizers are easier to control because you can actually see how much fertilizer you’re using and where it’s being dispersed. Advantages of slow release fertilizers are that the nutrients are available gradually over time. This means that the gardener can fertilize less often, and the nutrients are provided slowly and steadily.
Fertilizers are a mix of nitrogen (N), phosphorus (P), and potassium (K). The ratio will be indicated by three numbers (the first is nitrogen, the middle number is phosphorous, and the third is potassium). We recommend using a balance fertilizer with micronutrients for plumeria.
Micronutrients – The Hidden Story…And, Often Only Delivered by Slow Release Fertilizers!
There are several nutrients essential to plant growth and health that are only needed in very small quantities. These are manganese, copper, iron, chlorine, and molybdenum and zinc.
Chlorine is necessary for osmosis and ionic balance; it also plays a role in photosynthesis.
Copper is a component of some enzymes and of vitamin A. Symptoms of copper deficiency include browning of leaf tips and chlorosis.
Iron is essential for chlorophyll synthesis, which is why an iron deficiency results in chlorosis.
Manganese activates some important enzymes involved in chlorophyll formation. Manganese deficient plants will develop chlorosis between the veins of its leaves. The availability of manganese is partially dependent on soil PH.
Molybdenum is essential to plant health. Molybdenum is used by plants to reduce nitrates into usable forms. Some plants use it for nitrogen fixation, thus it may need to be added to some soils before seeding legumes.
Zinc participates in chlorophyll formation, and also activates many enzymes. Symptoms of zinc deficiency include chlorosis and stunted growth.
