It’s time for a love-in and a few lessons about the stuff we shove our precious plants into… soil! This episode we’re speaking to not one, but two expert scientists on what’s going on in the ground. Dr Magdalena Boshoff clues us into the world of nematodes and Dr Jassy Drakulic fills us in on fungi. Plus we chat with horticulturist Joe Lofthouse about how to choose the best compost bin to improve the soil in your garden.
