A wax coating on the seeds?
Never heard of that before. I'm thinking that maybe it's to prevent moisture from making the seeds germinate before you actually want them to.
So there must be something you do to prepair the seed for planting.
Instead of throwing out those silica packages, I put them in with my seeds in a sealed jar to absorb any moisture.
I've heard of using your fingernail to scrape certain types of seed before planting, which will increase your germination rate.
I usually get my seed from Burpee's and Harris Seed Co. I'll have to look through my catalogues, see what I can find out.
My gardens are still under two feet of snow. It was almost four feet, so I'm gettin' there.
Dug out my heat pads for the flats. I'll be starting my lettuce next month.
