What to do if Milan leaves turn black

1. Causes of blackening

There are many reasons why the leaves and branches of Milan turn black, such as unsuitable cultivation environment, unsuitable temperature and humidity, and incorrect use of fertilizers. For blackened Milan, you can solve it in the following ways.

2. Solution

For blackened Milan flowers, we can first cut off the leaves and branches connected to the dead branches. When the soil in the pot is relatively dry, cut off the black and rotten roots and plant it back in the pot.

1. Cultivation environment

Planters should not change the soil for flowers newly bought from the market, especially do not fertilize Milan. You should know that plants have their own adaptation process. It is recommended that you let the Milan flowers adapt to the cultivation environment first, such as humidity, temperature, light, etc. Otherwise, it will easily damage the vitality of the plants and be detrimental to their later growth.

2. Humidity

It is recommended that you place the plant in a warm, dry place away from direct sunlight. The best temperature is between 20 and 35 degrees, and it can bloom as many as five times in summer and autumn. Generally speaking, the fragrance of flowers is strongest when the temperature is above 30 degrees. On the contrary, if the temperature and light do not meet the requirements, the fragrance of the flowers will be very faint.

3. Water volume

Milan should not be overwatered. When watering, water the original soil thoroughly. If the flowers come from a greenhouse, spray water in the early stage to keep them moist. If the soil in the pot is too moist, you can take the soil and the Milan out of the pot. It is recommended that you do not water too frequently. Do not water the Milan flower unless it is dry. If you do water it, make sure it is watered thoroughly.

4. Sunlight

In winter, the plants can be moved indoors to balconies, windowsills, etc. Except for the strong shade needed during midday, you can provide the plants with sufficient sunlight. As for the newly sprouted Milan flowers, we must not overexpose them to the sun.

5. Fertilization

When Milan does not have enough nutrients, the leaves of Milan will turn black. When Milan blooms many times and the flowers are extremely lush, the flowers consume more nutrients each time they bloom. Therefore, the grower should replenish nutrients in time after the flowers fall, and can use acidic flower soil rich in leaf mold. Only in this way can the flowers bloom continuously and the branches and leaves grow luxuriantly. In summer and autumn, you can spray nutrient solution every week to ensure the plants are lush and green.
