Propagation. What is it and how can you do it?

Put simply, propagation is the process of making more plants from existing plants. This is a great way to get more plants without having to buy more seeds or seedlings. There are many ways for you to propagate your plants and we will go through some of the main ways this can be done:

Propagation by sowing seeds from your plants

One of the cheapest and most efficient ways to propagate from your existing plants is to harvest and pot seeds distributed from your plants. Collect these seeds and store them in a cool dark place until it’s time for you to sow them. Some good quality, peat free, compost along with some plug trays will be all you need to get going along with some regular watering (taking care not to leave the seeds in standing water as they will rot). The biggest challenge with this method is maintaining a constant temperature and ensuring the soil stays moist. Some trays will come with lids however a trimmed plastic bag or clingfilm can be used as a cheaper alternative.

Cutting plant roots for propagation

This is a great propagation option if you are interested but not quite ready to get going just yet! Root cuttings are best taken between November – March which is when the root has plenty of energy stored up for spring.

When selecting your roots, they should be at least 5mm in diameter. These will be the younger roots which will be hardier to being cut and removed. Always try to make a clean cut with some sharp pruning and make a diagonal cut to help the parent plant recover and grow new roots once it’s replanted.

Once you have your roots, cut them up into 3-6 inch long lengths with a horizontal cut at the top and a diagonal cut at the bottom. Now you are ready to plant your root cuttings. Fill up your container with cutting compost (usually a mix of peat substitute and perlite/sand) and place your root cuttings in about 2 inches apart from each other (horizontal cut at the top and diagonal cut at the bottom). Water lightly and ensure the cuttings stay away from any cold weather. Then next spring you should have new plants which have fully rooted in their pots and are ready to move on!

Propagation by division

This is a great option if you like getting your hands dirty! This method is best used for perennials (plants that live for more than one year).

When you are ready to divide, look for a suitable point at the base of the plant where you can divide. You need a plant which has produced more than one shoot/stem so you can separate these and divide the roots between them.

Once you have found your divide point, you can gently pull the plant into two. Alternatively, you can use a sharp knife or spade to slice the roots into two. Once you have done this, repot the separate plants, water well and ensure they are in a pot allowing drainage so the roots won’t sit in water.
