Typical Usage Rates:

This should help you calculate how much fertilizer you need for your plumeria.

  • 4-4 1/2" pot = 3/4 tablespoon
  • 6" - 1 gal pot = 1-2 tablespoons
  • 8” - 3 gal pot = 3 tablespoons

To be more accurate, it depends on the size of your plant. The larger the plant, the larger the root ball. Using a rule of 1 tablespoon per 1” trunk diameter near the soil line.

Each 4 lb package contains approximately 120 tablespoons.

Excalibur should be applied dry and, for best results, covered with about an inch or two of soil for even distribution and watered well to release nutrients.

Excalibur is a slow release multi coated granular fertilizer designed to release nutrients when plumeria need them during their growing season.  The release rate has been calculated to last approximately six months for Excalibur 11-11-14 and nine months for Excalibur 11-11-13. 

How it feeds your plants:

  • Application of Water
  • Release of Nutrients
  • Decomposition of Poly coatings

The advantages of slow release fertilizers are that the nutrients are available gradually over time. This means that the gardener can fertilize less often, providing nutrients slowly and steadily. This is how most plants prefer to be fed, and it helps them grow well. Granular fertilizers are easier to control because you can see how much fertilizer you use and where it's being dispersed.

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 a balanced fertilizer with micronutrients for plumeria with an NPK of 11-11-14 or 11-11-13 Excalibur. 

Micronutrients - The Hidden Story...And, Often Only Delivered by Slow Release Fertilizers!

Several nutrients essential to plant growth and health are only needed in very small quantities. These are manganese, copper, iron, chlorine, molybdenum, and zinc. 

  • Chlorine is necessary for osmosis and ionic balance and 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, so an iron deficiency produces chlorosis.
  • Manganese activates some important enzymes involved in chlorophyll formation. Manganese deficient plants will develop chlorosis between the veins of their leaves. The availability of manganese is partially dependent on soil pH.
  • Molybdenum is essential to plant health. Plants use molybdenum to reduce nitrates into usable forms. Some plants use it for nitrogen fixation. Thus, some soils may need to be added before seeding legumes.
  • Zinc participates in chlorophyll formation and also activates many enzymes. Symptoms of zinc deficiency include chlorosis and stunted growth.
  • Boron plays a vital role in a diverse range of plant functions, including cell wall formation and stability, maintenance of structural and functional integrity of biological membranes, movement of sugar or energy into growing parts of plants, and POLLINATION and SEED SET.

    I purchased this fertilizer to use on my first rooted plumeria stems. They have grown incredibly and one has even bloomed after only 4 months. It really helps with strong growth and flowering. Love it!
