What should I do if I have leaf spot problems in Milan?

Before the emergence of seedlings in the production area, the plants can be treated with 70% methyl tobuzine 800 times solution, or 50% tobuzin wettable powder to control the development of pathogens during transportation.

The disease occurs seriously in shaded and poorly ventilated places. Attention should be paid to ventilation and light transmission in cultivation management, and indoor plants should be regularly placed under light, and diseased leaves or fallen leaves should be removed in time. Before and after the onset of the disease, 75% chlorothalonil 500 800 times solution, or 1% Bordeaux solution, or 1200 times potassium permanganate solution can be sprayed.

During the transportation process, most of them are packaged in plastic film to facilitate moisture retention, which is easy to induce the onset of latent infectious diseases. Therefore, for the export of Milan, try to bring a slightly larger soil ball, and use a better breathable packaging material. Mechanical damage should also be reduced during shipment, and an isolation layer should be added to facilitate ventilation.

It is Milan leaf spot disease, which can be sprayed with 1000 times of 70% methyl tobuzine wettable powder.

In addition, it is necessary to pay attention to the usual management.

First, the temperature should be suitable. Milan loves warmth, and the higher the temperature, the more fragrant the flowers it produces. Generally speaking, the temperature is above 30, and under sufficient sunlight, the flowers will be fragrant; On the other hand, if you are in a shade with insufficient light in the environment below 30, the flowers will not be as fragrant as they are when the temperature is high.

Milan is home to a suitable temperature range of 20 to 35 and blooms up to 5 times between June and October.

Second, the light should be sufficient. Milan should be in a sunny place in all seasons. If you place Milan in a well-lit and well-ventilated garden or balcony, with 8 to 12 hours of sunlight a day, the leaves will be dark green, the branches will grow thick, the flowers will bloom more often, the flowers will be bright yellow, and the fragrance will be stronger.

If Milan is left in a shaded environment with insufficient sunlight, the leaves will be long, thin, the number of flowering will be reduced, and the aroma will be light.

Third, fertilization should be reasonable. Milan has strong flowering and many flowering times, so nutrients must be replenished in time. Every time Milan finishes flowering, it should be replenished with nutrients, and insufficient fertilizer is the main reason why Milan only grows leaves and does not bloom or leaves and buds.

Therefore, when the temperature rises, Milan should be moved to the outside for maintenance, and after a week, the soil should be loosened, some thin nitrogen fertilizer should be applied, and 10% to 20% of the decomposed cake fertilizer water or human feces and urine can be used, and then liquid fertilizer should be applied every 10 days or so to promote the growth of its branches and leaves. From June, Milan enters the peak growth and flowering period, which lasts until mid-October. Every 15 days or so, it is necessary to apply a concentrated fertilizer mainly phosphate fertilizer, or spray potassium dihydrogen phosphate solution every 15 to 20 days, and the flowering will be more luxuriant.

Special attention should be paid to the flowering period must be mainly phosphate fertilizer, otherwise there will be only leaves and no flowers. During the flowering period from June to October, if there is insufficient fertilization, not only will the number of flowering decreases and the flowers will not be fragrant, but the buds that have already appeared will wither and cannot open.

Fourth, watering should be timely and appropriate. The number of times you water the plant depends on the size of the plant, the change in climate, and the place where it is placed. Phosphorus and potassium fertilizers are applied before flowering, and there is often sunlight scattering, and the water is moderate, and its flowering aroma will be strong.

Summer is the peak growing season in Milan, and the water demand also increases, usually once a day. In hot and sunny weather, you can water it once a day in the morning and evening. If there is a lack of water, the leaves will turn yellow or even fall off.

In case of showers, pour water into the side basin after the rain to prevent root rot.

If you want to raise plants well, you must always pay attention to the four major factors that affect their production: temperature, light, fertilization, and watering.

Melasma of Milan leaves is usually caused by poor soil, too much light, too low temperature, improper watering.

1. Soil replacement: After the soil becomes poor, it should be replaced as soon as possible, and the new soil should have good ventilation and drainage.

2. Shading: In summer, you should block the strong light, or move to a place with astigmatism.

3. Keep warm: In winter, you should raise it indoors, but don't heat up immediately after being frostbitten, and take a break in a cool place first.

4. Reasonable watering: watering is dry and thorough, and timely drainage in the rainy season.

Milanese flower care instructionsThe maintenance of Milan flowers requires special preparation of soil, selection of nutrient soil, pine needle soil, perlite, etc., application of appropriate amount of farm fertilizer, treatment of Milan flower roots, potted plant maintenance. Usually give it enough light, water appropriately, prevent water accumulation, and apply potassium dihydrogen phosphate regularly.

Regular fertilization should be applied to the maintenance of Milanese flowers, and fertilizers should be applied in different states, potassium dihydrogen phosphate should be used when pregnant buds, and compound fertilizer should be used for maintenance when new shoots are grown. If you want to have a large amount of flowers during flowering, you can apply sheep manure to supplement nutrients. Then it is necessary to prune regularly, prune off the thin branches and leaves, the broken branches and the long branches, and then apply an appropriate amount of potassium dihydrogen phosphate.

1. Supplement sunlight.

Melasma on the leaves of Milanese flowers may be caused by a lack of light, and melasma will appear when plants that have been in the shade for a long time cannot photosynthesize.

2. Eliminate germs.

Melasma on the leaves of Milanese flowers may be caused by infectious bacteria, so it is necessary to cut off the infected leaves with sterilized scissors, and then spray carbendazim for sterilization of Milanese flowers, spraying them every other week.

3. Increase the temperature.

Milanese flowers are suitable for growing in a warm environment, if the temperature is too low during the maintenance period, it will cause the plant to be frostbitten, so that the leaves appear melasma, so in the winter to build a greenhouse for Milanese flowers, after a period of time the leaves will return to green.

4. Supplement nutrients.

If the nutrient absorption is insufficient during the growth period, it will also lead to melasma on the leaves, so it is necessary to apply a well-rotted organic fertilizer to the plant every other month, and apply a compound fertilizer based on phosphorus and potassium during the flowering period to increase the aroma of the flowers.

Precautions for the cultivation of Milanese flowers

1. Control the sunshine time.

Milan flowers need sunlight all year round, preferably 12 hours a day. Therefore, it is best to place Milanese flowers at home outdoors or in a sunny place on the balcony, so as to ensure that the leaves are bright green and fragrant.

2. Replenish fertilizer in time.

Milanese flowers like fertilizer, and if they cannot be supplemented with fertilizer in time and reasonably during the growth period, the plant will wilt. Milanese flowers bloom many times a year, and nutrients are depleted quickly, and if nutrients are lacking, it is difficult for the plant to bloom, or the flowers fall before they bloom. Therefore, it is necessary to replenish fertilizer in time after flowering to prepare for the next flowering.

The fertilizer can be slightly thicker during the growing period, and the number of fertilization can also be increased appropriately during the flowering period.

3 "wrong" ways to raise Milan flowers, make a leaf yellowing and flutter off.

Melasma on the leaves of Milanese flowers may be infected with the disease, so it is necessary to prune off the infected leaves in time and spray fungicides around the area. It may also be caused by insufficient light, and it needs to be transferred to a well-lit environment for maintenance in time. It may also be caused by too low a temperature, so it needs to be moved indoors for maintenance in time during winter maintenance, and the leaves will return to color after the temperature stabilizes.

Melasma on the leaves of Milanese flowers may be infected with the disease, so it is necessary to use sterilized sharp scissors to prune off the infected leaves to avoid further deterioration of the situation. In addition, it is necessary to spray fungicides around the leaves every week** to gradually restore the health of the Milanese flowers.

Milan flowers are suitable for growing in a sunny environment, if they are placed in a dark place for long-term maintenance, it will cause Milan flowers to be unable to photosynthesize normally, so that melasma appears on the leaves of Milan flowers, at this time, Milan flowers need to be transferred to a sunny location for users, so that they can receive sufficient light.

Milanese flowers are suitable for growing in a warm environment, and the temperature is too low to cause frostbite on the Milanese flowers, so that the melasma appears on the leaves of the Milanese flowers, so it is necessary to transfer the Milanese flowers to a warm room for maintenance in winter, and after the temperature is stable, the leaves of the Milanese flowers will gradually return to verdant green.

Poor nutrition will also lead to melasma on the leaves of Milanese flowers, so in the vigorous growth period of Milanese flowers, it is necessary to apply well-rotted organic fertilizer every 1 month to speed up the growth rate of Milanese flowers, and compound fertilizers based on phosphorus and potassium fertilizers need to be applied during the flowering period of Milanese flowers to avoid malnutrition of Milanese flowers.
