After 4 yrs I decided it was time to replace the soil in my first mini garden & re-set the scene.
Removed rocks bigger than the aquarium gravel & all non-plant objects.
That made it look naked.
A pic of Lithops in case they don't survive the experience.
The soil surface had sunk about 2 inches.
I pulled each plant out.
With styrofoam block removed. I scooped the gravel off of the surface with my hands. Having lined the bottom with window screen was a great idea. It made removing the old soil so easy.
Getting rinsed/cleaned.
I put the "patio" area a little farther back & to the right so more plants can fit on the more sunny left side.

I'm going to wait a few weeks to replace gravel & decorations to try to let the soil set in place so it's as airy as possible for plants to recover from the disturbance and hopefully doesn't compact so badly again.
