Starting in mid-July and through the fall is a time of the year when even the most inexperienced gardener can practice vegetative propagation of new plants from existing plants. For most gardeners, it is sheer joy to turn a thriving plant that you love into several new plants to thrive and love! Plant division can feel like magic.
The signs that a plant might benefit from division include:
• Crowding.
• Reduced flowering or smaller foliage.
• The center of the plant is not growing, a bald spot.
There are some general timing guidelines that are helpful:
• Divide after bloom is complete, at least four weeks before frost.
• Plants that bloom in spring, in general, should be divided in late summer to fall; this gives the root system time to establish before winter
• Fall blooming plant
