We have a north facing front garden and there is a horrible dank smell near to our front door. The house itself doesn't smell damp at all - I'm sure it is coming from outside. I have sniffed all around the door etc, and I'm pretty sure it is coming from a plant, but I don't know which one! Is there anything I can do to get rid of the smell, short of pulling up the whole bed? Are there any known culprits for this sort of smell?
Sorry for the basic questions - I am a first time gardener and know nothing about any of it!
