How to manage mango trees in spring

For larger inflorescences, it is best to cut off 1/3 to 1/2 of the lateral flower branches at the base. In order to reduce the effect of tree nutrition consumption caused by large amount of flowering on fruit setting. Second, timely topdressing mango trees with large flowering capacity should be fertilized in time from the last flowering to Xiehua. The trees with weak tree potential can be foliar sprayed with urea 015Mel 0kg, or compound fertilizer 0kg 25Mel 0kg, or combined spray with urea 0.5%, borax 02Mel 0.3% and potassium dihydrogen phosphate 0.3%, and trees with weak tree potential can be sprayed with 50 Mel 100 mg / L gibberellin.
