You can use those plugs if ya want.. Just need to drop it in the hole when it cracks open. Need not wait to get a dragon tail on it. I know it was hard to plant. Those plugs are kinda hard to wallow out,anyway.. I do like them cause of being organic matter.

Now I see the top of it.. Your gonna do fine! If you use soil? Use some of the other suggested soils other than MG.. Use that when they are 10 inches tall or so. They'll be able to handle the soil better at that time.
