The process of separating a mature hosta plant into multiple smaller plants is a form of vegetative propagation. This horticultural technique yields genetically identical offspring, preserving the desirable traits of the parent plant. A typical scenario involves carefully excavating an established clump and using tools to cleave the crown into sections, each containing roots and growth buds.
This practice invigorates the original plant, preventing overcrowding and promoting healthier growth. Furthermore, it allows for the expansion of hosta collections or provides plants for sharing with other gardeners. Historically, division has been a standard method for multiplying prized plants, allowing enthusiasts to propagate rare or unique cultivars.
