Mats that have plants attached should be planted by burying just the bottom of the mat in your substrate. The top of the mat with the plant should not be buried at all. The best way to do this is to move the mat carefully back and forth as you push it down in your substrate. The weight of the mat itself and having it in your substrate should hold it in place. If it does not stay in place, you can add plant weights to the bottom of the mat by inserting them into the mat. Click HERE to view the weights.
