Q.Can I prevent creeping thyme from extending from my flower garden into the lawn ?
I have a break in a stone garden border because of tree root that intersects the stone border. I did not want to damage the root but thought I could plant creeping thyme to fill in the gap. Will the thyme invade my lawn ?

It probably will invade your lawn eventually. It tends to crawl over and under barriers if it's healthy. The upside is that it mows nicely; some people replace their lawn areas with it. Read about creeping thyme here:
