If you closely look at the plants....The bottom of the are attached to a rock, The big center piece is a large lava rock. I took the roots and planted each root inside the lava rock holes, with a safety pen, (you will need something small but thick to insert them, I choose a safety pen. lol) And I have gotten some sewing thread and wrapped ard the lava rock...Thee other plants I used stones (from the pet store) and used lil black rubber bands to attach them. It I jus covered the rock with gravel. You have to use some type of rock/stone/ wood. Gravel will Kill the plants. U cannot suffocate the roots! I hope that helps just a lil I'm still a beginner in this...and its going well. Its all about research!!
