1. When Milan first went to the basin, it was watered once, and it should be watered less within half a month to promote new roots. In summer, the temperature is high, the evaporation is large, and the watering amount is slightly larger; During the flowering period, the watering amount should be reduced appropriately to avoid falling buds. After autumn, the weather turns cold and grows slowly, so we should control the amount of watering. The principle of watering is to water it when it is dry, or not to water it when it is dry. In hot summer, water can be sprayed around the leaves or flowerpots before sunset to increase the humidity of the environment.

Although Milan likes sunshine, it should be shaded at noon in midsummer to avoid burning leaves in the hot sun. Milan likes fat. During the vigorous growth period in summer, Qin Ying used alum fertilizer made of broken bones, fish intestines and hoofs to fertilize. Appropriate application of liquid fertilizer containing more phosphorus can make Milando blossom with rich fragrance and golden color.

2, potted Milan, generally two years need to turn over the pot to change the soil 1 time, do not break the soil, remove some of the old soil without roots, cut off the rotten roots. When adding new soil, add some phosphate fertilizer as base fertilizer, not too much. Marinate the pot in the shade, and move it to the sunny place after about one week. Generally, it is more appropriate to change the soil for about a week after going out in spring.

Milan is afraid of cold, and it is very sad for winter. When the temperature is lower than 12℃, fertilization should be stopped and watering should be reduced. Before the first frost, it should be moved to the sunny place indoors, and the temperature should be kept at about lO- 12℃. In order to protect the leaves, properly spray the branches and leaves with warm water. If the temperature is low, you can also cover it with plastic bags for a while, but leave holes in it to breathe.

In the next spring, you can't go out until the temperature is stable, so as not to freeze the plants in spring. Before leaving the house, plants should have an exercise process to adapt to temperature changes. For example, move out to bask in the sun at noon and move back at night; When potted plants are placed indoors, the windows are gradually opened.

The Milan you just bought may not adapt to the environment, because it grew in the greenhouse before you bought it. When I get home, the temperature, humidity and light are not as good as those in the greenhouse, and the humidity of the pot soil is not well controlled, so the flowers I just bought will wither and fall off when I take them home. Another possibility is that you are from the north and the Milan you bought is imported from the south, and the phenomenon you mentioned will also occur.

6. Milan likes light, ventilation and wet soil. Compared with other plants, the most important thing is to keep the soil acidic. When watering, ferrous sulfate can be added to the water at the ratio of 1: 1000.

Disease and prevention

1. Aphids, spray plants with cigarette butts or pepper water. You can also spray 800 times mirex solution. If the quantity is small, you can brush it manually with a small brush. Other control methods can refer to rose.

2. Beetle, spray 1500 times the medium. When the quantity is small, you can brush it manually with a brush. Other control methods refer to Clivia grandiflora.

3. Starscream, use 10% propargite EC (such as Guoguang Hongsha) 1000 times or 1000% propargite EC (such as Guoguang Hongsha) 1000 times +5.7% emamectin benzoate EC (such as Guoguang Leke). ?

4. Soot disease, high temperature and humidity and poor ventilation are all easy to cause this disease, so please pay attention to temperature and humidity and ventilation when raising.

Treatment method of fallen leaves

First, there is too much water, which will lead to Milan root can not breathe, water can not be transmitted to the leaves, resulting in suffocation and rotten roots. There is too much water in Milan. At first, the leaves below curled and dried up, turned brown and fell, causing the green leaves above to fall in a short time.

Second, water shortage, long-term water shortage, will lead to the root death of Milan. Watering Milan again at this time will leave many leaves in a short time, leading to plant death. There are many reasons, such as improper fertilization, poor ventilation, frozen leaves and so on.

Overwintering management

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.
