Free Heat

broad beans germinate in warm bag if barkThe bags of freshly chipped bark that are waiting to be spread on the paths in the garden have provided an unexpected benefit. When I noticed how quickly the bark was heating up, it occurred to me that I could use them as giant propagators. The broad beans that had shown no sign of germinating in the greenhouse started to shoot after 3 days in their cosy new quarters. Very satisfying. There is an extraordinary amount of bacterial and fungal activity in the chippings, so much so that I’m taking the precaution of wearing a face mask when spreading it to avoid inhaling the smoke-like clouds of dust. For the photo I moved one of the seedboxes to one side to reveal the network of fungus that has formed.
