In Milan, there are usually two kinds of leaves: big leaves and thin leaves. The aroma of big leaves is very light, while that of thin leaves is relatively rich. In addition to variety characteristics, cultivation conditions often affect aroma emission. If phosphorus and potassium fertilizer are applied before flowering, and there are frequent sunlight scattering and moderate watering, the fragrance will be stronger when flowering; If more nitrogen fertilizer is applied before flowering, or it is too shady, or there is too much water, the fragrance of flowers will be very weak, or even stop spraying.

Milan is generally potted, and its seedlings must have complete roots and soil to be cultivated. You can change pots or pots in spring, summer and autumn. Dry and broken pond mud is often put on the basin in the south, while acidic culture soil or surface sand is needed on the basin in the north. Culture soil needs proper fertility, including 25% humus soil, 50% compost and 25% river sand. The bottom of the basin should be padded with more tiles or put a small amount of fully decomposed cakes to facilitate drainage. First, put the upper pot under the shade shed for maintenance, spray water on the leaves 1 ~ 2 times a day (less water for half a month), and then move it to the light for maintenance after the new shoots appear, and then start topdressing with dilute sesame paste residue water before and after the new potted flower seedlings arrive in beginning of autumn. Top dressing 1 time every 20 days in the peak season from the second year. If potassium dihydrogen phosphate 1000 times can be applied at intervals, the flowers will flourish. Pot soil should always be moist, such as indoor furnishings need to be rotated once every half month. In winter, enter the middle-temperature greenhouse for wintering, let them see direct light and pay attention to ventilation. Generally, it should be placed on a high platform near the south of the greenhouse, and the room temperature should not be lower than 10℃. Water less, stop topdressing and prevent scale insects. From the end of April to the beginning of May next year, it will be moved outdoors and maintained in the leeward. Milan should pay attention to plastic surgery from the beginning of seedlings and keep the trunk of 15 ~ 20 cm. The lower branches of perennial plants are often aging and dying, so they are cut short 1 time every year or every other year to promote their germination of more lateral branches.

The fragrance of flowers in Milan is rich and lasting. High-pressure flaking can be used to breed in the south. In the north, in late May, peat mixed with flour and sand is often used as cutting substrate for cutting twigs, and plastic film is used for strict moisture preservation. After beginning of autumn, the rooting rate can reach about 60%, and it grows at seedling stage.
