Rational fertilization, watering and pruning are the key technical measures for flowering and fruiting of potted bergamot.

Plants newly planted in pots in the first year, such as pot soil with high fertility, can generally not be fertilized in that year. In the spring of the following year, the decomposed cake fertilizer can be applied once every half month or so, and it can be applied continuously for 2 ~ 3 times. In the middle and late August, decomposed organic fertilizer will be applied again. If the fruit begins in the third year, fertilization can be managed according to the routine.

Generally, when changing pots in early spring, sufficient base fertilizer is applied, mainly consisting of rotten bean cake residue and a small amount of bone meal. After the seedlings are delayed, put them outdoors in the leeward and sunny place, and apply thin water every half month or so until the buds appear. Spraying with 0.2% potassium dihydrogen phosphate solution 1 ~ 2 times during bud pregnancy. Apply pancake fertilizer every 10 day after fruit setting to promote fruit development.

In order to prevent bergamot from turning yellow, 02% ferrous sulfate solution is poured every half month during the growing period to keep the soil slightly acidic and the basin soil moist. In summer, water should be sufficient, and water should be often sprinkled on the ground around branches and leaves and flower pots to cool down and humidify. The basin soil should be dry in rainy season to prevent excessive growth. Water should be properly controlled at the initial stage of fruit setting to avoid excessive fruit dropping, and water should be gradually reduced after beginning of autumn. In the northern area, the first frost should be moved indoors, put in a sunny place, watered once every 1 week, and the room temperature should be kept at 10℃. Prune once a year before germination in spring to cut off dead branches, pests and diseases, slender branches and over-dense branches. The short branches of bergamot are mostly fruiting branches and should be preserved. In summer, slender branches, over-dense branches and long branches can be cut off to produce fruit branches. Summer shoots from June to July should be properly picked. Autumn shoots should be properly preserved for next year's results.

Bergamot can blossom and set fruit many times a year, but some flowers degenerate and cannot be pollinated. Generally, the ovary in the middle and upper inflorescence is large, and the bud with green flower center has high fruit setting rate, so it is necessary to leave more such flowers. When the fruit grows to the size of beans, thinning some young fruits according to the tree condition is not only beneficial to the large and symmetrical fruit, but also beneficial to the annual fruit.
