Choose a healthy plant, such as sorbus, holly, cotoneaster or rowan, and check the berries are ripe by squeezing them. Remove a generous bunch with secateurs.
Squash the berries onto a sheet of kitchen towel and clean away the skin and flesh to expose the bare seeds. Alternatively, clean away the flesh by running them under the cold tap in a sieve.
Fill a small pot with gritty loam-based compost and sow the seeds evenly across the surface.
Sprinkle a layer of compost over the seeds, water, then stand the pot in a cold frame or sheltered place in the garden. Keep it watered and protect it from birds.
