I'm due to move house and yesterday we had a quick look at the property. Both front and back gardens are quite overgrown with various pots and plants throughout. The front lawn has crocuses which look lovely, one biggish patch and some scattered further along. I didn't know this was a thing and my first thought was to dig them up and replant but am I better leaving where they are? How do I care for them if I leave them and can I pick them to display?
