What is Milan like? Is it easy to raise?

Evergreen shrubs or small trees. Stellate rust scales appear on the tips of young branches, and then fall off. Odd pinnate compound leaves, alternate, leaf axis with narrow wings, 3-5 leaflets, opposite, obovate to oblong, blunt apex, wedge-shaped base, glabrous on both sides, entire, with obvious veins. Panicle axillary. These flowers are yellow and very fragrant. Calyx 5-lobed, lobes rounded. Corolla 5 petaloid, oblong or suborbicular, longer than calyx. Stamens and filaments are combined into a tube, which is shorter than petals. Pistil ovary ovoid, densely covered with yellow coarse hair. Berry, ovoid or spherical, with stellate scales. Seeds have fleshy arils. The flowering period is July-August, or four seasons. Like warm, humid and sunny environment, not cold-resistant, slightly tolerant of shade. Loose and fertile slightly acidic soil is the best, and the temperature in winter is not lower than 10℃. ?

Milan likes warmth, sunshine and fatness. The optimum growth temperature is 20℃ ~ 25℃. Under normal circumstances, when the sunshine is sufficient and the temperature is high (about 30℃), the flowers will have a strong fragrance. If you put it in the shade in summer and apply a lot of nitrogen fertilizer at the same time, it is one of the main reasons why Milan doesn't bloom or bloom less and its fragrance is weak. Therefore, during the growth and development of Milan, it is necessary to maintain it in a sunny place outdoors, and pay attention to the appropriate application of liquid fertilizer containing more phosphorus. It is best to use rotten alum water such as broken bones, fish bones, chicken bones, etc., and often add some fertilizers containing more phosphorus or fermented rice washing water, which is helpful for budding, flowering, golden color and fragrant smell. ?

Milan likes humidity, so water it properly during the growing period. Too much watering can easily lead to rotten roots and yellow leaves falling off; Too much watering during flowering period is easy to cause falling flowers and buds; Too little watering will cause leaves to dry up and buds to wither. Therefore, when the temperature is high in summer, in addition to watering 1 ~ 2 times a day, we should often spray branches and leaves with clear water and sprinkle water on the ground to improve the air humidity. At the same time, fertilization should be appropriate. Because Milan has a large number of flowers a year, it is necessary to topdressing 2 ~ 3 times of fully decomposed dilute liquid fertilizer in time after each flower, so that the flowers can bloom endlessly and have a strong fragrance. Milan likes acidic soil, and humus-based culture soil should be used for potted plants. In the vigorous growth period, spraying 0.2% ferrous sulfate solution once a week will make the leaves turn green and the flowers multiply.

Potted Milan seedlings should pay attention to shade and avoid strong light. After the seedlings grow new leaves, apply fertilizer 1 time every two weeks, but the watering amount must be controlled and not too wet. In midsummer, in addition to shading the sun at noon, we should also see more sunshine, so that Milan not only blooms many times, but also has a strong fragrance. Winter maintenance in the area north of the Yangtze River must be moved indoors. ?

Loose, well-drained and breathable soil for potted plants. ? 65438+ change pots every 0 ~ 2 years, and 65438+ fertilize every 0 ~ 2 weeks. Planting in many gardens in the south; Potted plants in the north should be planted in outdoor places where the sun can shine directly in spring, summer and autumn. In winter, it will be moved to a place with direct sunlight indoors, and the overwintering temperature will be above 10℃. ?

After flowering, the adult mother plant will bear oval small red fruit, like bitter tree fruit. When the fruit is reddish brown, pick it, soak it in warm water, peel off the fleshy peel, then sow the seeds in a sand basin with the harvest, and germinate in summer and autumn for about one month. It takes two or three years for the seedlings to blossom, unlike the seedlings propagated by high-altitude layering, which can be full of strange fragrance that year.

Milan is native to the tropics and can't stand the low temperature. Generally, when first frost arrives in beginning of winter, he will move indoors and put it on a sunny windowsill or desktop. The indoor temperature should be kept at 8- 10℃, preferably not lower than 5℃. If the temperature is too high, the shoots will grow, reducing adaptability and cold resistance. Plants should not be close to stoves or furnaces; Using plastic cover can adjust the temperature and humidity, but it is necessary to cut one or two cracks at the top of the cover to avoid excessive temperature and humidity and affect normal growth. ?

When the soil is dry, water it slightly, but don't fertilize it. When the weather changes suddenly and the indoor temperature drops below 5℃, special measures should be taken to keep warm, such as moving potted flowers under the table at night, hanging a cloth curtain on the table, and keeping warm with a grass curtain under it; You can also put a plastic bag on the flowerpot, remove the cover curtain when the sun comes out the next day, and bring the potted flowers back from under the table. In Milan, it is not advisable to open the window for ventilation, so as not to be hurt by the cold wind.
