What if the unfragrant leaves of Milan flowers fall off?

Some Milan have luxuriant branches and leaves, but many flowers are not fragrant, so some people think that this is a difference between varieties, but in fact it is completely caused by poor management. Milan's management should pay attention to: the growing season should be placed in a well-ventilated place where you can get more than 5 hours of sunshine and shade for half a day; do not apply more nitrogen fertilizer, but should use fertiliser containing more phosphorus and potassium or alum made of livestock hoof horns and fish scales; temperature below 15 ℃, over-concentrated fertilizer, soil containing alkali or over-acid, too weak or too strong light will have different effects on flower fragrance concentration.

Some Milan leaves fall off at the base, forming top-heavy and light-footed, affecting ornamental and growth. When this happens, you should immediately pick the heart and control the overgrowth, and for the newly formed inflorescence, you should remove 1 pear 2 to make the leaves have sufficient nutrient supply and prevent the lower leaves from falling off; prevent the cold wind or the wind from falling off, so as to facilitate the recovery; check whether the basin soil is alkaline and whether there are insect pests, whether there is too much watering, fertilization or the use of raw fertilizer, and should be prevented and treated immediately if there is any.

Milan is prone to a large number of defoliation in winter, which is extremely disadvantageous to the growth and flowering of the following year. First of all, it should be observed from the signs that the leaf black brown wilting is a symbol of freezing, which should be warmed up or moved to a warmer place in time to make it gradually recover. The withered and yellow leaves are caused by poor ventilation or too dry soil. The shedding of green leaves is caused by the excessive wetness of the soil, so we should start with prevention and gradually stop fertilizing and reducing water when the climate turns cool. After the beginning of winter, the physiological activity of Milan is weak, so avoid low temperature, high humidity or dry air. Continuous low temperature below 5 ℃, aisle wind, long-term lack of light and other reasons will also cause leaf loss. Should always keep the leaf clean, especially to prevent lampblack, so as not to interfere with foliar respiration and photosynthesis. Postponing entering the house in autumn to exercise its ability to keep out of the cold, and leaving the room when the temperature is stable after the Qingming Festival in spring, which is conducive to the protection of leaves.
