The ti-logs (both the red and the green variety which we sell) are a cutting of the stalk of the plant. As such, they are not "roots" and so do not require burying.
Instead, we recommend this:
- lay the log(s) on its side
- use your fingers to push the log into the soil just so that it's secure
Basically, it will only be about 1/4 deep into the soil.
