How to prevent and treat rose rot? Sharing practical methods
Roses have brilliant colors and a pleasant fragrance. They are a famous raw material for fragrances, and also a flavoring raw material for smoking tea, making wine, and various sweet foods. Their value is very high, and on the international market, the price is higher than gold. Roses like sunlight, so the cultivation site should be chosen in a sunny, dry place; they do not bloom easily in shaded areas. As for soil and climate...
Rose rot mostly starts from the base of the petals and the flower stem. This rotting phenomenon has nothing to do with humidity or temperature; rather, the roses are damaged by ethylene during storage. The entire branch and stem fibers of the rose become lignified, and the flower stem is the most fragile part, and it must bear the weight of the flower head. Therefore, the flower stem is most vulnerable to pathogen attack, which triggers endogenous ethylene production. A large amount of nutrients being supplied upward is blocked and accumulates here, generating a large amount of heat, which accelerates maturity and rot. Therefore, when roses rot, the base of the petals and the flower stem often show alcoholic rot and falling flowers and petals within 1-2 days.The best way to prevent this phenomenon is to carry out preservation treatment after the roses are harvested, so as to strengthen the lignified growth of the fibers at the flower stem and prevent endogenous ethylene production. If preservation treatment is not carried out after the roses are harvested, the flower shop should also carry out corresponding preservation treatment after receiving the goods.
