Pruning a Fargesia robusta 'Campbell'
Prune Fargesia robusta 'Campbell' sparingly to maintain its natural fountain shape, typically once a year. To enhance its dense growth and visual appeal, remove any older, less vigorous culms from the base of the clump. Pruning should focus on thinning rather than shaping, allowing the bamboo to retain its robust, upright habit. This species boasts impressive winter hardiness, tolerating temperatures down to -17.8°C, making it a resilient choice for USDA zone 6b. Always ensure the use of clean, sharp tools to prevent damage to the bamboo's culms.
