It’s the easiest and most natural way to grow more of your favourite plants for free. Excitingly, while the resulting new plant could look the same as the parent plant, it could also look strikingly different, taking various qualities from both parents.

The best time to collect seeds is on a dry day, after a spell of dry weather, and around mid-morning, once any dew has evaporated. Seedheads that dry, such as sweet peas or poppies, should rattle. Always place dry seeds into a paper envelope or bag. Avoid storing seeds in polythene bags, which trap moisture and encourage mould.

Remove the seeds from the ripe fruit, sow straight away into a pot and place outdoors so it gets a period of cold. Watch this video on sowing hawthorn seed for more information.


Storing seeds

Most seeds will store for a year or two. Ensure they’re thoroughly dry first before putting in paper envelopes. Freezing will preserve many seeds almost indefinitely, but again, they must be thoroughly dry first. If you have any doubt, chill rather than freeze them in a fridge or outdoor shed, in jars, paper bags or envelopes.
