Fertilising a Fargesia robusta 'Campbell'
To maintain the vigorous growth and the striking green and blue hues of the foliage, it is essential to fertilize bamboo 'Campbell' twice a year. Apply a balanced, slow-release fertilizer designed for woody plants in early spring to kickstart growth, and then again in mid-summer to sustain its development during the peak growing season. Since this bamboo variety has a rapid growth rate of 50-75 cm per year, providing adequate nutrition is crucial for supporting this robust growth.
Although the species is resilient and adapts to various soil types, ensuring that the soil remains well-drained will facilitate the effective uptake of nutrients. Given its lack of drought resistance, it's important to maintain consistent moisture levels, especially after fertilizing, to help dissolve and distribute nutrients effectively.
