Our plant bio-nutrition sticks contain calcium gluconate, magnesium sulfate complex, and nitrogen fertilizer. They can promote plant growth, quickly provide the nutrients plants need, make plants grow more densely, and keep trees and flowers vibrant all year round. The method of use is very simple: just take an appropriate amount of the nutrition sticks and place them at the roots of the plants. They can promote robust plant growth, maintain the balance of water and nutrients in plants, and ensure healthier plant growth.
