Kumquat Tree How to Fertilize
Correct fertilization is very important for the flowering and the result of kumquat. Kumquat trees are fertilized three to four times a year. The first time is spring fertilizer, and it is applied in early February. Slow-effect organic rotting fertilizer is the main ingredient. Appropriately combined with quick-acting fertilizer, kumquat is generally sprouted in late April. For early application, besides providing germination, drawing shoots and spreading leaves, it will provide nutrients for flower bud differentiation. The second summer fertilizer was applied in early June. At this time, the summer shoots had stopped growing and provided nutrition for the kumquat flowering (three flowerings: early flowering, summer flowering and autumnal flowers). Fertilization is the most important once fertilization result for kumquat. The third time is autumn fat, which is applied in about mid-October, mainly to supplement the nutrient deficiencies of the whole tree after flowering. At the same time, it also prepares the kumquat tree for the cold winter to improve the winter cold resistance. The above-mentioned secondary fertilization mainly uses quick-acting fertilizers. The fourth time after the kumquat tree fruit set, it can be sprayed with 2 potassium dihydrogen phosphate solution to increase the absorption of potassium. The amount of the above-mentioned secondary fertilization depends on the type of fertilizer, the size of the tree, and the cultivation method (land-planting and potted plant) to determine the amount of fertilizer, and should not cause excessive fertilizer damage.
