Celebrating spooky season with spooky gardening. I've been trying my hand at my completely uneducated interpretation of the phrase "herbal topiary" and have been experimenting. Only killed one plant so far. Anyway, I used moss as mulch in this Thai basil by mixing up a clump with soil and spreading it evenly, and the results look good enough that I made my alfalfa into a little bonsai type thing with some of the haunted Cherry st. moss.
