Plant propagation means that you can make new plants free of charge. Gardeners can save money by growing their plants instead of buying them from the nursery.

Plants can be propagated by taking cuttings, collecting seeds and dividing rootballs. You can extend the life of some shrubs or herbaceous plants by propagating them.

To propagate plants, you don’t require a lot of equipment. It would help if you had some gritty compost and a container or two to store the seeds.

Propagating by saving and sowing seed

Sowing seeds in a seed tray

Planting plants from seeds is the most cost-effective and efficient way to propagate plants. To conserve energy, leave some seedheads on the plants after they have finished flowering. The seed can be saved in an envelope for the next spring or immediately.

Propagating by layering

To encourage rooting, you can attach a strawberry runner to the ground.

When stems come in contact with soil, drooping trees and shrubs can grow roots. Plants like strawberries have runners that allow them to root quickly and produce new plants. These natural methods can be modified by ensuring the runners or stems come in contact with prepared soil. This is known as ‘layering.

Propagation by division

Divide an established perennial plant using two large garden forks

Dividing perennials is an excellent way to propagate them. Dividing plants is a great way to rejuvenate them. Because there’s less root material competing for nutrients and water, it’s best to do this in spring or fall. You can make strong plants by dividing large amounts of already established plants and choosing vigorous growth.

Propagation by basal cuttings

Stem cutting with a knife

Basal cuttings are the new growth that sprouts in spring from a crown, tuber or stem. You can remove them with a sharp knife at the ground level and plant them in gritty compost to encourage root formation. Although it is not the most efficient propagation method for plants, taking basal cuttings can be very rewarding.

Propagation from root cuttings

Planting root cuttings into a modular tray

You’ve probably tried to move an oriental poppy, Acanthus rubrum or Acanthus spinosus and failed. However, any root left behind can be used to grow new roots. The same principle can be used by gardeners who dig up the roots and cut small pieces to make them into pots.

Propagation from stem cuttings

Growing plants from stem cuttings

Stem cuttings are taken by removing stem pieces and potting them up. This encourages them to grow roots. Some plants are more difficult to propagate using stem cuttings than others. Hardwood stem cuttings may be taken in the summer, while softwood can be taken in the winter.
