I just purchased creeping thyme seeds to put in a pathway that has Bermuda grass. I am planning to dig out as much of the Bermuda as possible, put a fabric weed cloth down and add about 4 to 5 inches of soil, place my bricks down and plant my seeds between the bricks. Will the weed cloth work or will it disrupt the creeping thymes growth? The cloth is just an idea in hopes to keep the Bermuda at bay.
I would personally not use the landscape barrier under your Creeping Thyme planting.
The purpose of the planting is to suppress and hold back weeds.
That said, if you do want to use the cloth, you should give the plants at least 8 to 10 inches of top soil.
