Fertilising a Campsis radicans 'Flava'
To support the vigorous climbing growth habit and the profusion of yellow blooms, Campsis radicans 'Flava' benefits from regular fertilization. Apply a balanced, slow-release fertilizer in early spring as new growth appears. This initial feeding will provide essential nutrients to kickstart the plant's growth phase. A second application of fertilizer should be made in the early summer to sustain the plant's energy needs during the peak blooming months of July, August, and September.
Given the plant's ability to reach heights of 7.5 meters, ensuring a reliable nutrient base is crucial for maintaining both the health and structural integrity of the vine. Well-drained soil aids in preventing nutrient leaching, allowing the plant to efficiently utilize the applied fertilizer for sustained growth and development.
