Division is a clever way for gardeners to grow their plant collection. If you are keen to learn new propagation techniques this year, learning how to divide plants is an interesting and cost-effective way to add more plants to your garden borders.

While many perennials and shrubs have a relatively high success rate when propagating by division - hellebores, for example - other plants are best left alone and should not be moved or divided. For this reason, planting in the right position is important, so it is always best to take the time to make a considered decision when placing new perennials and shrubs in the yard.
