Hi, High Country - I don't blame you! I've used well established methods myself - and have done so on and off for the last twenty years. I'm not suggesting anyone adopts this method or even tries it. Found the page, wondered if anyone had any experience and knew this would be the place to find out. Like I said, I'll give it a go next time I re-pot just out of curiosity. It won't cost me anything to find out. I'll report back here whatever the results - even if it's only to tell the rest of the community that it's pointless. I'm doubtful that it'll work as I'm sure others might use it already if it did but, if it does, then there's potential for dozens of cuts every few weeks for soil growers so, for me, it's worth a go.Think I'll stick to the normal method thanks.
