Three weeks after I bought the roses from the market, they faded and the buds couldn&;t open. What&;s the matter? Answer: This is a normal phenomenon. Before the Spring Festival every year, I buy several different types of flowers and put them in vases with appropriate amount of water. Roses are flowers cultivated in greenhouses, and they grow and develop through various measures such as warm and suitable planting, fertilization and pesticide application. When they can be shipped, they are cut and packaged with scissors and transported to flower shops everywhere for sale. Of course, I can&;t raise them when I buy them home, and they will wither in about 20 days. Thank you all.
