Typical Usage Rates:
- 4 -4 1/2″ = 3/4 tbsp.
- 6″ – 1 gal pot = 2 tbsp.
- 3 gal pot = 3 tbsp.
- 5 gal pot – 4 tbsp. (1 oz = 2 tbsp.)
- Grown in the ground, use approximately 1 – 2 tablespoons per inch of trunk dia. Depending on how many branches the tree has.
Excalibur is a controlled release polyon coated fertilizer designed to last approximately 6 months for Excalibur VI and 9 months for Excalibur IX (depending on which you use). It is applied dry and is best to cover with about 1″ of soil for even distribution, it needs water to release nutrients.
How it feeds your plants:
- Application of Water
- Release of Nutrients
- Decomposition of Poly coating
Advantages of controlled-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. This is how most plants prefer to be fed and helps them grow well. Granular fertilizers are easier to control because you can actually see how much fertilizer you’re using 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 phosphorus, and the third is potassium). We recommend a balanced fertilizer with micronutrients for plumeria with an NPK of 11-11-13 or similar to Excalibur.
Micronutrients – The Hidden Story…And, Often Only Delivered by Slow or Controlled 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.
- Boron plays a key 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.
- 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.
