Fertilising a Incarvillea delavayi
For optimal growth and the most robust flowering, it is prudent to fertilize Incarvillea delavayi regularly during the growing season. Begin by applying a balanced, slow-release fertilizer in early spring to support the initial burst of foliage and the development of the striking purple and pink blooms. A second application should be applied as the first flush of flowers starts to fade, usually in late spring or early summer, to encourage continued blooming throughout the season.
It is essential to follow the recommended dosage on the fertilizer package to prevent over-fertilization, which can lead to excessive foliage growth at the expense of flowers. Well-drained soil is important for the health of Incarvillea delavayi, and an appropriate fertilization regimen ensures that the plant maintains vigor and displays its full ornamental potential.
