How to fertilize pear trees for good growth? A detailed guide to fertilization methods
How to fertilize pear trees for good growth? Please give an introduction. The life of a pear tree goes through several main growth stages: the young tree first-fruiting stage, the full-fruiting stage and the aging stage. At different growth stages, the fertilizer required differs. 1. Young tree first-fruiting stage: In early spring, a nitrogen-based fertilizer should be applied as a top dressing. After early summer, when new shoots stop growing, flower buds begin to differentiate and the fruit begins to swell, a phosphorus- and potassium-based fertilizer should be applied as a top dressing. After harvesting the fruit in autumn, a base fertilizer should be applied once more. 2. Full-fruiting stage: After bud break and before flowering, apply a nitrogen-based fertilizer once as a top dressing. From late June, when the fruit begins to swell, until just before harvest, root-zone top dressing (foliar spraying) should be carried out, and nitrogen, phosphorus and potassium fertilizers should be applied together during top dressing. After the pear fruit is harvested, the tree enters a recovery stage, and during this period the base fertilizer should be applied early. 3. Aging stage: After decades of growth and fruiting, the pear tree enters the aging stage, and four top dressings and one base fertilizer are applied throughout the year (an average of 250-500 kg of barnyard manure per tree each year).
