What if the leaves fall off?

There are often star-shaped rust-colored scales at the top of the branchlets; pinnately compound leaves alternate, flowers yellow, extremely fragrant, about 2 mm in diameter. Bisexual pedicel slightly short and thick, calyx 5-lobed, petals 5, oblong; berries subglobose, 10-12 mm long, flowering between summer and autumn.

Culture methods and matters needing attention of Cymbidium

1. The temperature should be suitable.

Milan likes warmth. The higher the temperature, the more fragrant the flowers will come out. Generally speaking, when the temperature is above 30 ℃, the flowers will smell good when exposed to sufficient sunlight. On the other hand, in the environment below 30 ℃, if they are in the shade of insufficient light, the flowers will not have the fragrance when the temperature is high. To cultivate Milan, the suitable temperature ranges from 20 ℃ to 35 ℃, and can blossom up to 5 times between June and October.

2. The light should be sufficient.

Milan should be in a sunny place all the year round. If Milan is placed on a well-lit and well-ventilated garden or balcony, and the light is more than 8 hours to 12 hours a day, it will make the leaves of the plant green, the branches grow stout, the number of blossoms more, the color of flowers bright yellow, and the aroma more intense. If Milan is left in a sunny and shady environment, it will make the plant branches and leaves grow and thin, reduce the number of blossoms and lighten the aroma.

3. Fertilization should be reasonable.

Milan blossoms strongly and blossoms many times, so it is necessary to replenish nutrients in time. Every time Milan blossoms, we should pay close attention to replenishing nutrients. The lack of fertilizer is the main reason why Milan only grows leaves but does not blossom or falls leaves and buds. Therefore, when the temperature rises, Milan should move to outdoor conservation. After a week, it will loosen the soil, apply some thin nitrogen fertilizer, use 10% to 20% rotten cake water or human feces and urine, and then apply liquid fertilizer every 10 days or so to promote the growth of its branches and leaves.

Since June, Milan have entered a period of vigorous growth and flowering until mid-October. If a thicker fertilizer based on phosphate fertilizer is applied every 15 days or so, or 0.3% potassium dihydrogen phosphate solution is sprayed every 15 to 20 days, the flower will bloom more luxuriantly. Special attention is paid to the fact that the florescence must be dominated by phosphate fertilizer, otherwise there will be only long leaves but no flowering. In the flowering period from June to October, if there is insufficient fertilization, not only the number of blossoms will decrease and the flowers will not smell good, but the buds that have already appeared will wither and cannot open.

4. Watering should be timely and appropriate.

The number of times of watering in Milan depends on the size of the plant, the change of climate and the place where it is placed, so as to be timely and appropriate. Increase the application of phosphorus and potassium fertilizer before flowering, and there is often sunlight scattering, the water is moderate, its flowering aroma will be strong. Summer is the peak growing season in Milan, and the water demand also increases, usually watering once a day. In the hot and sunny weather, water can be watered once every morning and evening. If there is a lack of water, it will make the leaves yellow or even fall off. In case of showers, pour water into the side basin after the rain to prevent rotting roots.

5. Pruning and changing pots

Milan has strong growth, rapid growth, strong germination and high nutrient consumption. in order to promote Milan to blossom for a long time, cross branches, long-growing branches, diseased branches and weak branches should be properly cut off in its growing season, especially in autumn. the dense branches and dry and withered branches should be cut off in time to improve the ventilation and light transmission of the plant so as to facilitate flowering. After each flowering, it should be combined with the tree type to pick the heart to make it produce more lateral branches, which can make Milan beautiful plant shape, various flowering and rich fragrance.

Potted Milan usually needs to turn the pot and change the soil once every two years, and the pot should be changed when Grain Rain comes out of the room. Milan likes moist, fertile, loose sandy loam, which is suitable for slightly acidic soil. 25% peat soil, 50% rotten leaf soil and 25% river sand can be mixed into nutritious soil. When changing the basin, be careful not to break all the persistent soil, remove part of the rootless old soil, cut off the rotten roots, add new culture soil, and put a small amount of hooves at the bottom of the basin as base fertilizer. After putting on the basin, it needs to be watered once, and a little water can flow out from the bottom of the basin, and then put it in a cool place for maintenance, which can be moved to a place with sufficient light for about 15 to 20 days for normal maintenance and management.

Is Milan poisonous?

Milan flower is non-toxic and can be placed indoors for a short time, but it grows better in a sunny, well-fertilized, ventilated environment.

Cause Analysis and treatment methods of Leaf loss in Milan

1. Watering: too much watering causes the root system to be unable to breathe and suffocate the root. Water cannot be transmitted to the leaf surface. What is shown is that at first the lower leaves curled, dried up, turned brown and fell off, which led to the shedding of the upper green leaves in a short time. Lack of water for a long time, resulting in root system withered, then irrigated with water, a large number of leaves will fall in a short time, and the plant will die. Watering should be strictly in accordance with the "see dry see wet", do not dry do not water, watering will be thoroughly. Basically, it is watered twice a day.

2. Fertilization: Milan flowers have certain requirements for fertilizer, especially during the growing period. If there is not enough fertilizer, the leaves will turn yellow and fall off. Fertilization should grasp the principle of frequent application of thin fertilizer, especially when topdressing in spring, do not apply thick fertilizer. Topdressing should be applied once every 10 days, and an appropriate amount of calcium superphosphate should be added in fertilizer and water, which is beneficial to the growth of Milan flowers.

3. Lighting: Milan flowers like light, which is generally cultivated under bright scattered light. If the room is relatively dark, it will affect the growth of Milan flowers and lead to yellowing and losing leaves. Milan should be kept in a ventilated and scattered place. You can see the morning light every day and move into the room at noon when the sun is shining. See the sunset as the sun sets. This process can last about half a month, so that Milan have a process of adaptation.

4. Diseases and insect pests: leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of leaves, yellow spots or patches appear, when the whole leaf is withered and yellow and shedding off seriously, and yellow-green mottle appears on the leaves after being infected by mosaic virus; suffer from shell insects, red spiders and so on. The clarification solution of 25 times dry and pure plant ash and superphosphate can be sprayed on the leaf surface every 15 to 20 days, or 0.1% lime water clarification solution can be used for pollution-free control, so as to protect branches and leaves and prevent all kinds of diseases and insect pests.

Solution:

If there is a large area of fallen leaves after watering, you can pad the Milan basin high, poke away the topsoil in the basin, and be careful not to damage the root system. Stop water and fertilizer, put it in a ventilated place, and spray water on the leaves sooner or later. Speed up the evaporation of moisture in the basin, and after Milan no longer has fallen leaves, it can gradually turn to normal management.
