Seed Storage Tips
The best place to store seed is in a sealed container in your fridge. Seed stored in a hot garden shed or garage that can reach temperatures greater than 40° in summer will simply die. Seed stored open to the air where it can take up moisture will lose viability.
Pectinase is useful if you have seed with the pulp still sticking on and no amount of sucking, scrubbing or soaking in plain water will remove it. Put in a teaspoonful mixed in water and leave it overnight and the adhering pulp will slip off the seed with gentle scrubbing the next morning.
