Planting around a tree in full sun
So... I have a large twisted willow tree with a very high canopy. There is a circle around the base where in spring I’ve got cyclamen bluebells etc. This summer o created a wild flower meadow circle but having just cleared it all away am left with a bare circle of earth. So help please: dry fryable but clay based soil, full sun, some tree roots! No grass/turf suggestions please!!
