Vitamin B1, also known as thiamine, is essential for healthy plant growth and development. It promotes nutrient absorption and protects orchids from stress caused by adverse environmental influences. Vitamin C also acts as an antioxidant and protects plant cells from oxidative damage.
Finally, vitamin E is involved in photosynthesis and protein synthesis in plants, while iron and zinc are important for the formation of chlorophyll and the overall health of orchids.
However, it is important to bear in mind that the use of supplements should not replace the appropriate care of the orchid and the creation of an environment that meets its needs.
