Low Cost Gardening - Collecting Seed

Gardening doesn't have to be expensive, and collecting your own seed is one way to propagate plants if you have a restricted budget.

Low Cost Gardening - Collecting Seed

It’s also very satisfying, relying on your own skills and watching your garden develop with plants that have been grown from seed you collected during the previous season.

How To Collect Seed

Collecting seed is quite easy. Wait until they are ready to drop from the plant. Then, on a dry day, arm yourself with a paper bag. Either pick the pods from the plant, cut off the seed head or shake the seed directly into the bag.

Native plant seeds can be sown immediately in gritty compost. These include Angelica, Foxglove, Sweet Cicely and Yarrow. Sow in seed compost using a 3in pot or in a seed tray and cover in a protective layer of grit before leaving outside in a sheltered position. Water sparingly if the compost dries out.

The cold and inclement winter conditions will then break down the protective seed covering and promote germination. If you want to appear knowledgeable, this is called 'stratification'.

To break the seeds' dormancy you can also place them in your refrigerator for a month and then sow them. The resultant seedlings can then be potted on singly and planted out when they are large enough.

Storing The Seed

Many seeds don't require frost to germinate and will need to be stored until the spring. The list of these includes Cosmos, Lovage, Marigold and Sunflowers.

After collection, you can sift the seed heads to remove the chaff and leave only the seeds. If the seeds are in pods, wait for them to dry and then extract the seeds.Store the seed in a cool and dark place. Use paper bags or food containers with a sachet of silica gel.

Start the seeds off in a greenhouse during the early spring or in a propagator when they will appreciate only a little water in the morning. They can then be potted on in a similar fashion to native plants.

Note that seeds from hybrid (F1) plants may not be worth collecting, they will either not be viable or will not have the same properties as the specially bred parent plant.

Of course, collecting and sowing seed will mean that you will continually have the same plants in your garden, so it's always worthwhile to augment them with a few others each year.
