Seed Collection

See The Garden, RHS February 2013, pp 58-62 for guidance on seed collection techniques.

Scarifying Seeds

This is when you scratch the surface of the seed coat.  The easiest way to do this is to line the inside of a glass jar with a piece of rough sandpaper – add the seeds and shake a bit.

Soaking Seeds

Some seeds can be soaked up to 6 hours before planting – such as narsturtium and peas.


This is when seeds are combined with moist potting compost and subjected to a period of cold or warm to simulate environmental conditions needed for germination.
