I like that! Looks really good!Very nice!
Here is one I recently startedView attachment 57590
I layers the bottom with 1" of hydrocottle, clay balls, then a window screen type sheet.
I layered a springtail culture on top of the screen and covered with my standard soil mix.
I sloped the substrate to allow planting of the live plant's root balls aside the cork bark round and packed around with moss, then topped with organic, dried live oak leaves.
I lightly packed the cork bark with moss and leaves and poured about a gallon of water in the "stump" over the course of a week.
I sprinkle some dried fish food in a few places to feed the springtails and have some safe bark, like cholla wood soaking that I will add in with the leaves.
Once everything thing grows in, I will add a spider.
