My daughter and I made what we’re calling a mystery terrarium yesterday. It’s a mystery because we used dirt from the front yard and some decomposed organic material scooped out of a crevice in the bed of our pickup truck for the soil and didn’t add any seeds or plants. The decayed organic hodgepodge from the truck bed is dark and rich and full of nutrients.
We gathered pebbles from the front yard and from the truck bed for a drainage base. We added a little circle of window screen above the pebbles to help keep the soil from migrating into the drainage base. We misted it with water and added a couple of local prehistoric denizens.
It will be interesting to see what grows in there. Surely there are lots of microorganisms and who knows what little critters in there. We’ll see if anything green starts growing.
