We moved here (Barrie, Ontario, Canada) 4 years ago.
In those 4 years we have been yanking out lilac roots from our entire backyard. I even began to wonder if we were on some old homestead whose house had been surrounded by lilacs. (We aren't. We are built on the remains of a small sand & gravel pit, created in the 50-60s to extend the highway 400 further north.)
There is one lilac bush, Syringa vulgaris, near the back fence. We live on a hill, and it is planted just over the crest of our little plateau, on the west side.
WHAT CAN WE DO ABOUT THESE INTERMINABLE ROOTS?
They pop up everywhere. In the veggie garden, along pathways, in pathways, in well-trodden areas, in little-used areas... and in our compost bins. arg.
Any and all suggestions welcomed.
(We can't have animals, so rooting by animals is not a do-able thing here.)
Thanks, everyone, for your thoughts.
