For those seeds needing smoke treatment to germinate, there is now available from South Africa smoke chemical impregnated paper discs which when soaked with your seed accomplish the treatment. I have used them with good results. Al

Thanks Al. I'll see if we've imported them at all.

There's a chap here who has converted an old fridge into a smoker using a roasting pan in the bottom, some untreated sawdust, and an assortment of leaves to smoulder like incense. Aussie and South African plant leaves. Then he puts his seeds in trays so they can be smoke swirled. We're talking cold smoking - not cooking (LOL).

Apparently it helps to break dormancy in some species - hence my query.

Meantime, I'm looking for the equivalent of asbestos sox for getting these leaves singed off and leaving the lavenders in peace.
