Courgette seed saving

Real seeds advice for cucumbers..........

Cucumbers need to be ripened well beyond the edible stage.  They will become much fatter, and green varieties will turn a dark yellow brownish colour, white varieties a paler yellow. Keep for a week or so after picking to let the seeds mature fully.  Then cut open, scoop out the seeds and surrounding pulp into a jamjar, add a little water and stir well.  Leave the jar on a sunny windowsill for 2-3 days for the seeds to ferment.    On the third day, fill the jar fully with water, and stir well again.  The good seeds should sink to the bottom of the jar, leaving pulp, debris and empty seeds floating on top.  Gently pour off the water and debris, refill the jar, and repeat.    After a couple of rinses, you should be left with good seeds at the bottom of a jar in clean water.  Drain off the water, and spread out on a plate to dry well.

Both melon and cucumber seeds will last for several years if dried well and stored somewhere cool.

EDIT This is from RS's leaflet

"Leave on the bush until fully mature at the end of the season. Rinse the seeds off and spread on newspaper to dry".
