        Sunburn
        Winter or summer injury to the trunk of a woody plant caused by hot sun and fluctuating temperatures. Typically, sunscalded bark splits and separates from the trunk.

        Woundwood – Callus
        After wounding, callus forms, woundwood is a tough, woody tissue full of lignin that grows behind callus When woundwood closes wounds, then normal wood continues to form.

        Carbon (C)
        Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.

        Hydrogen (H)
        When they photosynthesise, plants use sunlight to break apart water into hydrogen and oxygen, and then combine the resulting hydrogen with carbon dioxide from the air to create carbohydrates.

        Calcium Carbonate
        Calcium carbonate is used to help prevent the spread of various diseases, such as powdery mildew, black spot, and blossom end rot. Calcium carbonate (as you may have guessed) bestows plants with a (1) healthy source of calcium, (2) pH balancing properties, (3) increases water retention ability within acidic soils, and

        USDA Zones
        Areas derived by the USDA that indicate average-low winter temperatures. Used as a plant hardiness indicator. Other plant hardiness zones developed by other entities use different numbering systems.

        Plumeria Dormancy
        Plumeria dormancy is a period of arrested growth. It is a survival strategy exhibited by many plant species, which enables them to survive in climates where part of the year is unsuitable for growth. Plumerias are tropical and a phase of innate dormancy coinciding with an unfavorable season, such as winter

        Did You Know

        Did you know Plumeria acquire different levels of Dormancy?
        Dormancy levels vary between plumeria. In general, the
        number of plumeria that may acquire dormancy shows a trend
        to increase with geographical distance from the equator and correlates with the occurrence of seasons.
        Variation can also be found within plant species. This has been
        studied intensively in the model species Arabidopsis thaliana
        (Arabidopsis), which is widespread in Europe and parts of Asia.
        and shows high variation in dormancy levels

        Did you know spider mites go dormant during cold weather?
        spider-mites have learned to go dormant when the length of hours of daylight start getting lower, seemingly aware that cold temperatures will soon follow. Other factors enter into it, such as temperature, but photo-period appears to be the main cause. The specific amount of hours of daylight required to bring on dormancy varies according to latitude (farther north, where it gets cold early, they go dormant sooner), but it's somewhere in the neighborhood of 13 hours a day of light everywhere. They don't all go into diapause at that same exact time, either, as individual spider-mites have quite a variance in their response to these stimulations.
