We have decided to cut down a lilac which has never been good value and which is too close to a hazel that we'd like to encourage. I notice that one branch of the lilac trunk, which was pruned about 18 inches above the ground a couple of years ago, has a white fungus on it near to where it was cut. Should I treat the stump with anything to try to prevent harmful fungus spreading into the ground?

The key to limit the spread of a potential fungus infection is to remove the food source which enables the fungus to leapfrog around your garden (don’t worry, the vast majority of visible fungi are benign and not dangerous). In short this is dead wood below ground – tree and large shrub roots. So the best advice we can give you is to dig out and remove as much as possible of your lilac stump.
