Zinc (Zn)
Growing and care
Zinc (symbol Zn), in commerce also spelter, is a metallic chemical element. It has atomic number 30. It is the first element of group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in the Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest mineable amounts are found in Australia, Asia, and the United States. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
Plumeria Database context: Zinc (Zn) affects how plumeria roots, leaves, stems, and blooms perform in containers or in the ground. Care terms are especially important because watering, drainage, nutrition, and soil conditions can change the way a plant looks.
What to look for: Consider the growing mix, drainage, watering cycle, fertilizer program, container size, root health, and local climate before deciding whether a symptom is a cultivar trait or a growing-condition response.
Identification note: This term is one clue. A plumeria should be compared using all available traits, photos, source history, and growing context rather than a single characteristic.
