Rice orchids are luxuriant in foliage and green, and when they bloom, the light yellow flowers are fragrant and refreshing. This is a very popular ornamental flower. Some flower friends say that the flowers in Milan are not fragrant. What happened? Let's get to know Uncle Gardener. First, there is not enough sunshine. Generally, there is no fragrance when flowering because there is less sunlight contact. This is the main reason, so it won't open or open less, and the fragrance is light. Because it likes to be warm and positive. Only when there is plenty of sunshine and sunshine, flowers will have fragrance and flourish. Under the right circumstances, the more sunshine, the more fragrant the flowers will be. Second, there is too little fertilizer because it costs a lot a year. If the fertilizer is not applied enough, the flowers that will bloom in the future may have no fragrance. Dilute liquid fertilizer can be applied 2-3 times after each flowering, which can not only ensure the number of flowers, but also maintain the fragrance. It is best to add more phosphorus fertilizer, or you can use self-made fertilizers such as fish bones and chicken bones to help propagate flower buds and keep the fragrance of flowers. Third, improper watering during growth, too much or too little watering will affect the flowering of plants, and the fragrance of flowers will naturally weaken. It can replenish water according to the growth state, and the temperature is high in summer. Besides watering 1-2 times a day, spray clean water on the leaves. Fourth, the temperature is not suitable. Milan likes warmth. In the process of reproduction, when the temperature is above 30, its flowers will be more fragrant under sufficient sunlight. Therefore, in order to make Milan orchids fragrant, it is best to maintain a suitable temperature environment. The breeding temperature between 20-35 is most suitable for Milan to blossom and grow. If the temperature is too low, the flowering period in Milan will not only be reduced, but also unpleasant.
