First, the causes of black spots
Milan mosaic is dry for many reasons, such as inappropriate cultivation environment, inappropriate temperature and humidity, improper use and so on.
Second, the solution
For smiles with black spots, we can cut off the leaves and branches attached to the dead branches. When the soil in the pot is dry, cut off the rotten roots with spots and pick the flowerpot back.
1, culture environment
Don't change the soil for the newly bought flowers from the market, especially don't fertilize Milan. You know, plants have their own adaptation process, so it is suggested that orchids should be adapted to the breeding environment first. For example: temperature, humidity, light, etc. Otherwise, it will easily lead to the original damage of plants, which is not conducive to the later growth of plants.
2. Temperature
Suggestions. Put the plants in a dry place without direct light. The optimum temperature is between 20 and 30, and Milan is colorful in summer and autumn. Generally speaking, the fragrance of flowers is the strongest when the temperature is above 30 degrees. On the contrary, the temperature and light can't meet the requirements, and the fragrance is very light.
3. Water quantity
Milan cannot have too much water. When watering, thoroughly water the original soil. If the flowers come out of the greenhouse, they can be moisturized by spraying water in the early stage. If the soil in the basin is too wet, you can take it out with Milan. It is recommended not to water orchids too often. If they don't do this, they don't need to be watered. If you water it, you must water it thoroughly.
4. sunshine
Milan can be moved to indoor balconies, window sills and other places in winter. In the strong noon, it needs shade, which can provide more sunshine for plants. For newly sprouted orchids, excessive exposure is not allowed.
5, fertilization
When Milan does not have enough nutrition, it will lead to black spots on Milan's leaves. Orchids bloom many times, and when the flowers are extremely lush, they consume more nutrients each time, so they can replenish nutrients in time when they are backward, and acid flower soil rich in rotten leaves can be used. Only in this way can a hundred flowers blossom and flourish. In summer and autumn, you can spray nutrient solution once a week to ensure the lush plants.
Third, the maintenance method
1. watering: when watering, the amount of water should be appropriate, and it can be watered once every two days. It is not advisable to water too much, which will make the roots unable to breathe, affect the normal growth of plants, and even die in severe cases. On the contrary, watering it too little will also affect its normal growth, resulting in the root can not absorb water. Gradually wither and die.
2, lighting: it likes the sun, but it is suitable for scattering light when breeding. Be careful not to be exposed to strong light to avoid sunburn. You can give it plenty of sunshine in the morning and before sunset. Pay attention to shading at noon and avoid light as well.
3, fertilization: Milan likes fertilization, but be careful not to apply too much, otherwise it will easily lead to large-scale defoliation, withering and so on. Fertilizer can be diluted with water containing bone fragments, fish intestines, etc. And more phosphorus-containing liquid fertilizer can be applied to promote its growth and flowering better.
4. Temperature: Milan is not cold-resistant and likes a warm environment. When the temperature is lower than 12, it will enter the dormant period and need to be placed in a warm indoor environment. The optimum temperature is about 10 to 12. If the temperature is too low, appropriate insulation measures can be taken.
5. Change pots: Milan can change pots and turn over the soil once a year or two, and properly cut off dead roots and rotten roots. After changing the basin, keep it in the shade for maintenance, and you can see the sun again in about seven days.
