I moved here 2 years ago and front garden was a decent sized square of lawn with no plants at all. I started digging up the lawn and making a spiral border that ultimately will fill the whole space with shingle paths following the spiral shape. Soon after I began I noticed a crop of fungi in a very regular pattern across the lawn. Honey fungus. I was therefore not surprised to find when digging huge fat roots of trees that had been cut down and the roots left. This has resulted in bent forks and a sore back plus the worry about the honey fungus affecting the plants I am putting in. Any thoughts on what plants would be at risk?
