Adhere to the principle of "applying thin fertilizer frequently", apply liquid fertilizer once before the plant sprouts, and then apply liquid fertilizer once every 7-10 or so, mainly nitrogen fertilizer, to promote its growth and more spring shoots. In the growth period of citrus, you can sprinkle some cake fertilizer on the basin surface to enhance the fertility. After autumn, reduce fertilization gradually to avoid over nutrition and fruit falling. Strictly control fertilization in autumn and winter.
Citrus on the soil requirements are not strict, appropriate choice of garden soil, and add a proper amount of sand, ash and rotten organic fertilizer mix.
