What to do if Milan flowers lose leaves

reason

Watering

Excessive watering will cause the roots to be unable to breathe, suffocating and rotting. Water cannot be transferred to the leaves. What manifests itself is that the lower leaves initially curl, dry up, turn brown and fall off, which in turn causes the upper green leaves to fall off in a short period of time. Long-term lack of water will cause the roots to wither and die. If you water the plant thoroughly at this time, a large number of leaves will fall in a short period of time and the plant will die. Watering should strictly follow the principle of “water when dry and water when wet”. Do not water if the soil is not dry, and water thoroughly when you do. Basically, water thoroughly every two days.

Fertilization

Milan has certain requirements for fertilizer, especially during the growing period, there must be enough fertilizer. If there is insufficient fertilizer, the leaves will turn yellow and fall off. When applying fertilizer, you should follow the principle of applying small amounts of fertilizer frequently, especially when applying topdressing in spring, avoid applying concentrated fertilizer. Top dressing should be applied every 7 to 10 days, and an appropriate amount of superphosphate should be added to the fertilizer water to be beneficial to the growth of Milan.

illumination

Milan flowers like light and are usually grown under bright scattered light. If they are placed in a dark room, it will affect the growth of the Milan flowers and cause the leaves to turn yellow and fall off. Milan should be placed in a well-ventilated place with scattered light indoors. You can see the morning light every day and move indoors when the sun is high at noon. See the sunset as the sun is about to set. This process can last about half a month, allowing Milan to adapt.

Pests and diseases

Leaf spot disease caused by fungi and other pathogens can easily cause local necrosis of leaves and the appearance of yellow spots or plaques. In severe cases, the entire leaf will turn yellow and fall off. After being infected by the mosaic virus, yellow and green spots will appear on the leaves; the leaves are also harmed by scale insects, red spiders, etc. The leaves can be sprayed once every 15 to 20 days with a clarified liquid obtained by mixing 25 to 30 times the dry and pure wood ash and superphosphate, or a clarified liquid obtained by 0.1% lime water, for pollution-free prevention and control, in order to protect the branches and leaves and prevent damage from various diseases and insects.

Solution

Ventilation and fill light

The newly bought Milan should be placed in a well-ventilated place with scattered light indoors. You can see the morning light every day and move indoors when the sun is high at noon. See the sunset as the sun is about to set. This process can last about half a month, allowing Milan to adapt. During the period of watering, strictly follow the principle of "water when dry and water when wet". Do not water if the soil is not dry, and water thoroughly when you do.

Stop watering and fertilizer

If there is a large area of ​​leaf fall after watering, you can raise the Milan pot and remove the topsoil in the pot, being careful not to damage the roots. Stop watering and fertilizing, place it in a ventilated place, and only spray water on the leaves in the morning and evening. Speed ​​up the evaporation of moisture in the pot, and after the Milan stops shedding leaves, you can gradually switch to normal management.

Extended light exposure

Gradually extend the sunshine time of Milan. Except for the need for shade under the scorching sun at noon, you can give it more sunlight. Promotes chlorophyll formation in leaves. During this period, watering should strictly follow the principle of "watering when the soil is dry and watering when the soil is wet", and basically water thoroughly every two days.

Pest and disease control

Potted Milan is seriously affected by powdery mildew, leaf spot, anthracnose, red spider mites, scale insects, aphids, rust mites and other pests and diseases, which cause the branches and leaves to turn yellow and die. Every 15 to 20 days, the leaves can be sprayed with 25 to 30 times the clarified liquid of a mixture of dry and pure wood ash and superphosphate, or 0.1% clarified liquid of lime water for pollution-free prevention and control, in order to protect the branches and leaves and prevent various pests and diseases.
