As adult results pomelo tree results to consume more nutrients each year, should follow the following several times for top dressing. Fertilizer dosage is calculated per plant, 1. Flower bud differentiation fertilizer: In late January to early February, the application of urea 1 kg, 70 kg of tung water, the purpose is to cultivate spring shoots (as a result of mother) and to promote flower buds Differentiation. 2. Thanks flower stable fruit fertilizer: In mid-April compound fertilizer 1 kg of urea 1 kg, 70 g of bran water 3.
