Pear Tree Spring Management
Fertilizing before buds, nurturing buds and flowering of strong trees require a lot of nutrients, and the nutrients stored by the trees themselves are far from enough. The development of flower organs (stamen and pistil) is dominated by fast-acting nitrogen fertilizers in front of the shoots. Each tree in the canopy drips has a depth of 2 cm and a depth of 30 cm. The length, width and length of the fertilizer depend on the age of the tree and the strength of the tree.
