Sowing larger seeds in plastic bag
Hello. A tip I learned from allotment gardener Terry Walton (radio 2, radio Wales et al) is that of sowing larger seeds in compost inside a plastic bag to check germination.
Rather than the hope method of sowing large seeds direct into pots-then the wait and see, what he does is place the seeds into moist compost inside a plastic bag. Give them approx 12 days, tip them out, and see which ones have germinated on. Those that haven't back in.
Simple and works well. So simple I never thought of it, lol!

snap Owdboggy. especially cabbage seeds from 1999. 30% germination but as I only wanted 6 plants it worked for me.

I use this method for daylily seeds but in slightly damp vermiculite instead of compost and they go in the fridge they can take 8-12 weeks to germinate but over 90% success rate :-)

Not new did that over 40 years ago, And sown seeds on filter paper in petrie dishes to check viability. And in agar jelly and in wall paper paste.
