Spring apple tree fertilization

The best time for applying apple tree fertilizer is to apply base fertilizer before germination in spring, and the fertilizer effect is slow. It has little effect on flowering fruit setting and new shoots in spring, but it will lead to excessive growth of tree in the later stage. Flower bud differentiation and fruit development. It is recommended to apply less base fertilizer as much as possible, and apply more foliar fertilizer. At the same time, it can be combined with spring irrigation and topdressing fertilizer, with nitrogen and phosphorus fertilizer as the main, with appropriate amount of potassium fertilizer. In order to promote flowering and fruit setting, the big tree should be applied with nitrogen fertilizer or foliar spray fertilizer from early March to early April. The flowering period can be sprayed with 2% ammonium sulfate, 0.3% potassium dihydrogen phosphate or 0.2% borax solution.
