In order to make orchids fragrant, the following points need to be done in maintenance:

1. The concentration of Milan flowers is directly related to sunlight. Under the temperature and illumination of 30 degrees of food intake, the leaves are dark green, the branches are stout, the flowering times are many, the color is bright yellow and the fragrance is strong. Whether the flowerpot is placed on the balcony or in the yard, it should be placed in the sun. Insufficient sunshine not only inhibits growth, but also reduces the amount of flowers, and the fragrance of flowers will also drop sharply. Appropriate shade should be provided at noon in midsummer. It can't be placed on the north balcony. The light on the north balcony is insufficient, which can't meet the needs of Milan's growth.

2. Another measure to make orchids fragrant is to apply more phosphorus and potassium fertilizer. Milan has the habit of flowering many times a year and consumes a lot of nutrients, so it is necessary to meet the energy supply, that is, to apply more chemical fertilizers at the right time. But it is best to spray after 6 pm.

Milan is a southern flower and likes humid environment. The dry climate in the north is not conducive to its growth. In the growing season, it is of great benefit to spray water and humidify the leaves many times. Potted soil should be neither too dry nor too wet. Too dry soil is prone to yellow leaves and dead buds. Too much watering can easily lead to rotten roots in Milan, and in severe cases, a large number of leaves will die.

4. If Milan is kept on the balcony, be sure to pay attention to ventilation. Poor ventilation is not only vulnerable to pests, but also causes a large number of leaves, buds and flowers to fall off in Milan.

Milan is a southern flower and likes acidic soil. It grows well in acidic soil, the basin soil is alkaline, Milan grows poorly and even dies. The water in the north is also alkaline. Long-term watering of tap water will make the soil alkaline, which is not good for Milan's growth. In daily maintenance, we should pay attention to improving the PH value of water, and reduce the pH value of water to below 6.5 before use.
