They ate the 30" tree mulch circles.
I used a 'utility knife', one that has the blade the slides out as you push the lever (like you might use for carpet). You may have to cut AGAIN, as the tree gets larger in diameter. (the tree will grow larger over time weather you cut the mat or not, but it will LOOK BEST AND NOT WRINKLE if you cut the whole bigger as the TREE GROWS. We have had out mats for several years and they still work and look great!! Kent P., Utah. I give them 5 stars. (But give them some attention over the years!)
