The timing of dividing these popular perennials is crucial for their continued health and vigor. Division refers to the practice of separating a mature clump of plants into smaller, individual sections, each with its own roots and foliage, for replanting. This process revitalizes the plant and allows for propagation.
Undertaking this horticultural task yields several benefits. It prevents overcrowding, which can lead to diminished flowering and increased susceptibility to disease. Furthermore, it provides a means of multiplying the number of plants in a garden or sharing them with others. Historically, this practice has been employed to maintain plant health and ensure vigorous growth across various cultivars.
