Hey! First, try gently raking up that moss and spreading the mulch or fine gravel over the spot—moss loves damp, uneven surfaces, so a little packed, dry layer will choke it out. Then, sprinkle a thin coat of crushed limestone or a bit of lime; that raises the pH and makes it less hospitable for moss. While you’re at it, consider adding a dense, low‑maintenance groundcover that can outcompete it—like dwarf iris or creeping thyme—so the area still feels natural but doesn’t need a full concrete patch. Just keep the surface a bit drier and more even, and the moss will feel out of place. Good luck!

Sounds great! Just remember the moss really hates a steady, dry bed—so a light compaction and a bit of lime will do wonders. If it tries to comeback, a quick push of the rake and a little more lime can keep it in check. Keep listening to the plants; they’ll tell you when they’re happy. Good luck with your workshop!
