Potted cherries are limited by containers, and the nutrient soil in the pot is difficult to meet the long-term nutritional needs of the roots. It is necessary to fertilize and supplement the potted cherries during the growing season.

Spring: once every 10- 15 days, pour cake fertilizer water (10g cake fertilizer plus 500g water per pot) or horseshoe horn water (10g horseshoe horn stock solution plus 500g water per pot).

Summer: Pour cake fat water or horseshoe horn water or a small amount of rotten poultry and fish viscera every 10- 15 days.

Autumn: In addition to applying decomposed organic liquid fertilizer according to the above method, 0.3% potassium dihydrogen phosphate solution can also be used to spray fertilizer on leaves for 2-3 times.

Topdressing should adhere to the principle of less and diligent, complete and sparse, and water every time after topdressing. Organic fertilizer must be fully decomposed before application to prevent root system from burning out.
