Vitamin B12 for Plants
General Information
Vitamin B12 is known as cyanocobalamin, it provides multiple benefits for plant growth and protection.
As a natural antimicrobial, vitamin B12 for plants increases disease resistance in crops to prevent losses. Foliar sprays of B12 solution have been shown to stimulate vegetative growth and flowering by enhancing cell division and metabolism.
Additionally, vitamin B12 promotes rooting, boosting transplant survival rates when cuttings or seedlings are pre-treated with diluted B12 solution. By stimulating root activity, it facilitates rapid root establishment after propagating new plants. The vitamin also elevates photosynthetic capacity in leaves for better light utilization and growth.
Seed soaking with vitamin B12 is an effective way to increase germination rates and seedling vigor as well by preventing fungal decay. With antioxidant and antimicrobial properties, vitamin B12 for plants improves plant resilience against biotic and abiotic stresses.
