Should you fertilize your potted rose tree in winter?
Potted rose trees can be stored in a cold room in winter to induce dormancy, which will make them strong in the spring. Before moving them into the room, prune them, clean the pot surface, spray lime water to eliminate pests and prevent diseases, and move them into the room before the pot soil freezes solid. Water them during the storage period to prevent drying out, and keep the room temperature around 0℃ for safety. When it's too cold, seal them with soil. In early spring, when it gradually gets warmer, open the ventilation to prevent yellow buds from occurring and affecting normal growth. You can keep them in a warm room during winter. After pruning, let them freeze outside for a while, then move them into the room at the end of November, first placing them in a low-temperature area to defrost slowly, then moving them to a place with a temperature of about 10℃ to wait for them to sprout. Then place them in a room with plenty of sunlight, requiring more than 4 hours of direct sunlight and a temperature of about 20℃. Water them sparingly, loosen the soil, and on sunny days at noon, you can place them outside in a sheltered and sunny spot to grow. When the new buds develop into branches, water and fertilize them moderately, and they can bloom around the Spring Festival.
Potted rose trees are relatively cold-resistant. They stop growing when the temperature drops to 4℃, and they can safely overwinter in a low-temperature environment of -10℃ without protection. If the roses overwinter indoors, they won't get enough dormancy, as the indoor temperature in most homes is above 5℃. If the room temperature is slightly higher, they will sprout and grow branches. However, due to insufficient sunlight and temperature, the branches will be thin and the leaves small, and the nutrients stored in the plant will be wasted, severely affecting the flowering and the quality of the color and fragrance of the flowers the following year. They may even gradually wither and die due to insufficient nutrient supply; or due to lack of cold training, they may have poor cold resistance and die from the cold wind after being moved outside in the spring.
The Nanyang Rose Planting Base points out that overwintering potted roses outdoors not only allows them to get sufficient dormancy and store nutrients for the next year's growth but also can freeze the overwintering pathogens and pests, preventing the occurrence of diseases and pests the following year.
So, should you fertilize your potted rose tree in winter? Many people have this疑问. Let's take a look at the detailed introduction by the editor from the Nanyang Rose Wholesale Planting Base:
Some people think that since the roses stop growing in winter, fertilizing at this time will result in wasted fertilizer, so fertilizers should be stopped in winter. However, fertilizing roses in winter should not use fast-acting fertilizers. It's best to use fermented organic fertilizers. Fermented organic fertilizers can not only provide nutrients for the roses but also insulate them, which is very important. Maintaining a stable soil for the roses in winter is very important for their safe overwintering and nutrient storage, especially in the northern regions, where organic fertilizers or compost should be used to insulate the soil when entering winter.
Winter is also a good time to apply unfertilized organic fertilizers. The decomposition process of raw fertilizers produces heat, but in winter, the temperature is relatively low, and the heat produced by the decomposition of organic fertilizers can offset the low temperature, raising the soil temperature.
After the winter fermentation, the roses will have plenty of nutrients available for growth in the spring. Roses bloom a lot in the spring and require a lot of phosphorus and potassium fertilizers. Fish intestines that have been fermented are natural phosphorus and potassium fertilizers, so in winter, you can bury raw fish intestines in the ground for the roses, and they will bloom a lot in the spring.
