Propagation: Division

My latest YouTube tutorial Propagation: Divison’ is a demonstration on how to divide herbaceous perennials and grasses to gain further plants.

Propagation: This is a method of producing more plants either by seed, cuttings or division. These categories can be further split up to methods such as layering, semi ripe cuttings, etc.

Division is a simple and effective way to propagate plants especially as named above grasses and perennials as the more woody varieties of shrubs tend not to produce off shoots or form in clumps.

It is also recommend that after a number of years herbaceous perennials and grasses should be divided to prevent their clumps getting too large and becoming too competitive.

This can lead to a dense growth which can cause too much shading for flowers to be produced or putting all their energy into producing shoots.

By splitting up these clumps you are allowing the plant to receive more light and reducing the likelihood of competition therefore creating a more suitable environment for flowering.

By watching the tutorial you can develop an understanding of how the process of how division is carried out. It is simply by cutting your plant apart either by a sharp knife or a good spade.

Depending on the size and variety of the plant, quite a number of individual plants can be successfully propagated, providing that a good root run is kept.

The growing medium is of particular importance as you want something with plenty of pore space to allow the roots to develop and that is also free draining.

I recommend either using perlite or a fine grit but vermiculite is also another option although it won’t offer as much pore space but rather more heat.

After potting on your plants it is important also to provide them with enough heat over the winter months i.e don’t allow them to be exposed to frost.

A window sill or porch is ideally suited or indeed if you have the access to a polytunnel or glasshouse is also suitable. Just be careful with the amount of sun light they are exposed to as this can lead the young shoots being scorched.
