I am looking to plant some creeping thyme on the edge of tall grass to keep it out of the garden, and am wondering if it will be able to push back against 4' tall grass bordering the garden.

  • No, it won''t, the grass will just carry on growing through the thyme or any other plant in its way

  • then why do they say to use it instead of mulch in places? Commented Jan 20, 2019 at 14:39
  • Can't comment, not sure what you mean. Who's 'they' and have you got a link to that information?

My experience on sandy soil is that it will, in combination with mowing. The advantage of creeping thyme is that you can mow it hard to say two inches and it will bounce back and even flower abundantly if you and the bees are lucky, but the grasses give up after a while. As the thyme gets thicker you have to mow less, but the thyme will survive where the grass eventually gives up. Even couch/quack grass will stay away. I use it on a bank where mowing is possible but inconvenient; it works well.

In really droughty weather patches will die out, turn black and be somewhat unsightly but eventually fills in again where the grasses won't stand a chance.

Update: I have posted a video on my patches of thyme among quack grass on sandy soil.

  • Thyme does not replace grass in USDA zone 4 and 5

  • @kevinsky I will support my claim with pictures, but not right now since the areas are covered in about a foot of snow and hard frozen. Feel free to remind me in about 4 months. Commented Jan 21, 2019 at 11:06
