Milan is a very favorite flower plant, when it blossoms, it will make the whole room fragrant and popular, but we will find that the Milan flower has lost its leaves not long after we bought it. It will not only affect the beauty, but also let the Milan flowers die, so what should we do if the Milan flowers lose their leaves? Next, let's take a look at the conservation knowledge of Milan flowers.

First, what is the reason why Milan spent its leaves?

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 calcium superphosphate can be sprayed on the leaf surface every 15 to 20 days, or 0. 1% lime water clarification solution and other pollution-free control, in order to protect branches and leaves, prevent a variety of diseases and insect pests.

2. What if Milan loses its leaves

1. Fertilization: fertilizer should be applied once a month, mainly organic fertilizer and high-efficiency phosphorus and potassium fertilizer, and avoid partial application of nitrogen fertilizer. In general, fresh water is watered once a day in summer and autumn, and every 2-3 days in winter and spring, so that water can quickly infiltrate into the basin soil and not accumulate on the basin soil. At the same time, it is necessary to often spray fresh water on the branches and leaves, especially during high temperature in summer and drought in winter, to spray all the branches and leaves evenly, so that it is appropriate to start dripping water, so as to keep the branches and leaves moist and how to prune Milan flowers.

Milan should start pruning and shaping from the seedlings and keep a section of the trunk 15 to 20 meters high. Do not let the trunk branches emerge from the soil, but should branch and prune above the 15-meter-high trunk to make the plant full. The lower branches of perennial plants often grow old and die. Therefore, the north should be cut every other year in high temperature season to promote the adventitious buds in the lower part of the main branch to germinate and grow new lateral branches, so as to keep the tree well-proportioned, strong, leafy and flowering.

Finally, when we find that the newly bought Milan flowers have lost their leaves, don't panic and think about what is wrong with the breeding process. Then in accordance with the above Milan breeding methods to save their own Milan, so that Milan back to life.
