Josh Byrne JOSH BYRNE: One thing I'm always banging on about is rock minerals.... _Some rock minerals... a little bit of rock minerals...a little bit of rock minerals...and rock
minerals_ ...and there's a reason why. Here in Perth, on the Swan coastal plain, I'm gardening on some of the worst agricultural soils in the world and as an organic gardener
who's keen on building up the soil to grow productive plants, I use things like compost and aged manures for body and nutrients, but also this stuff. Now contrary to popular belief,
it's more than just crusher dust. In fact, it's made from a blend of carefully selected rocks and mixes things like basalt and gypsum and lignite and rock phosphate and these are
ground up into a very, very fine dust and then they're prilled to form these little pellets to make it easier to scatter and when they're wet, they dissolve into a fine just again.
But there's something more... it's also been inoculated with a range of microbes and it's these microbes, when they come back alive, are what convert the minerals into a
plant-available form and that's why it's so good and that's why I want to keep on banging on about it! COSTA GEORGIADIS: Orchids come in all different shapes and sizes. In
fact, orchids are one of the largest plant families in the world. But Clarence has only got one type on his mind - native orchids.
