Will the富贵竹 die if its roots are cut? 富贵竹 root cutting and maintenance techniques. (Note: "富贵竹" is a specific plant name, which is translated as "FORTUNE BAMBOO" or "Bamboo Plant for Wealth and Fortune" in some contexts, but since it's a proper noun, it's kept in Chinese with an explanation in parentheses for clarity.)

Will cutting the roots of the富贵竹 (Fortune Bamboo) kill it?Fortune Bamboo, as a widely popular ornamental leaf plant, often causes concern among plant enthusiasts when it comes to root pruning. The lush green stems paired with elegant leaves can often be saved with scientific pruning when facing root issues.Through systematic maintenance and care, even with the roots cut, the plant can revitalize.I. Key to Survival After Pruning the Roots of Fortune Bamboo1.1 Safe Threshold for Root PruningHealthy plants can endure pruning of up to 70% of the rootlets, retaining main roots over 3cm to maintain basic absorption functions. Experimental data shows that in a room temperature of 25°C, plants with 30% of their roots retained sprouted new roots 7 days earlier than those that were fully pruned.1.2 Principles for Treating Diseased PlantsWhen the stem shows black rot or yellowing, the affected area must be removed simultaneously. Observe the cut with a magnifying glass to ensure the cross-section is creamy white without brown streaks, which is a crucial criterion for survival.II. Post-Pruning Regeneration Care System2.1 Hydroponic Regeneration PlanAdopt a triple water level control: initially submerge the cut 3cm deep, lower to 2cm after new roots sprout, and maintain 1cm when the roots exceed 5cm. Add 2 drops of a special nutrient solution weekly, and it is recommended to use a brown, light-blocking glass container.2.2 Soil Cultivation Techniques for RevitalizationThe recommended substrate ratio is珍珠岩:泥炭土=1:3, with a planting depth that buries two nodes. Use the bagging method for moisture retention in the first two weeks, opening the bag for ventilation for one hour daily.2.3 Environmental Control FactorsMaintain a day-night temperature difference of 5-8°C and keep the light intensity between 8000-10000Lux. Use a thermometer and hygrometer to monitor, ensuring daytime humidity is ≥60% and nighttime ≤75%.III. Special Root Growth Promotion PlanWillow extract as a substitute for root growth stimulants: Soak 200g of current-year willow branches for 24 hours, then dilute the filtrate 3 times before use. Big data shows that this method can increase the root formation rate by 23% without chemical residue.By precisely controlling pruning intensity and scientific care, Fortune Bamboo can fully achieve root regeneration. The key is to master the three core aspects of disinfection and sterilization, environmental control, and nutrient supply, along with patient observation, usually within 28-35 days, the damaged plant can be restored to its ornamental value.
