What to do with rotten roses
As a deeply loved ornamental plant, roses often make flower friends speechless. Based on the typical symptoms of rotting rose roots (yellowing leaves, wilting branches, peculiar smell of soil, etc.), this paper systematically analyzes the rescue steps and maintenance points to help you save endangered plants in time. Detailed explanation of the steps to deal with rotten rose roots 1. After the plant is urgently removed from the pot and signs of root rot are found, water and fertilizer must be stopped immediately. Select a cool period to remove the plant completely with soil, and the movements need to be gentle to avoid secondary damage. Focus on the color changes of the roots: healthy roots are milky white, while rotten roots are dark brown and soft and rotten. 2. Deep root treatment Rinse the roots with running water until completely exposed to prepare disinfected gardening scissors. When pruning, keep 1cm of healthy tissue as a buffer and cut off all rotten roots. It is recommended to soak in 50% carbendazim 800 times solution for 20 minutes to simultaneously prevent bacterial root rot. 3. Plant shape and prune to retain 3-5 bud points on the main stem, and remove all leaves and thin branches. Apply healing agent to the incision after trimming to reduce moisture evaporation. Special reminder: Summer operations need to avoid the high temperature period at noon, and it is recommended to carry out it in the morning/evening. Key to rose rejuvenation and maintenance 4. The basin soil system should be renewed and the original basin needs to be scalded with boiling water or disinfected with potassium permanganate. Recommended formula for the new substrate: 30% perlite +20% pine scale +50% leaf soil. After planting, use the basin method to supply water to maintain the micro-moisture of the substrate, and avoid watering with large water. 5. During the recovery period, key maintenance points need to be placed in a scattered light ventilation place to maintain the humidity of 60%-70%. Fertilization is prohibited in the first 2 weeks, and organic fertilizers such as seaweed are applied after new buds germinate. Daily maintenance suggestions: Water for 5-7 days in spring and autumn, spray in the morning and evening in summer to increase humidity, and control water and stop fertilization in winter.
Through the three-step first aid method of root treatment, plant pruning, substrate renewal, and later scientific maintenance, the rotten root roses can be restored to vitality. Regularly checking the humidity of the basin soil, mastering the principle of "seeing wet when it is dry", and cooperating with the quarterly application of microbial bacterial fertilizer can effectively prevent the recurrence of rotten roots.
