Carlindi, at the wonderful secret nursery Verdure Plants, suggested the answer to my seed raising troubles might be perlite and generously gave me some to try.
I was reminded that I have, in fact, used perlite but mine was much bigger lumps pressed into service, experimentally, as aggregate in a concrete sculture. It was supposed to make the concrete strong but light. Sadly, not light enough…
It was the sculpture that caused me much embarrassment when an unruly trailer jack-knifed itself in the carpark at Mindarie Keys. The mess of trailer, car and weighty sculpture were so mangled it requried the assistance of a posse of male artists to fix. It’s an unwritten law that one should be able to
manhandle manouevre one’s own sculture.
