White crust on pots
Has anyone seen a white crust on your pots? Any ideas what this could be?
I've noticed some on two 12"-wide pots. They're almost like snowflakes in appearance. It turns to a dust if you touch it.
On one pot, it appears like a horizontal band on the middle (fattest) part of the outside of the pot. But it also runs along the interior of the top lip (not in contact with soil).
The close-up photo (which is the interior of the top lip) shows about 3 inches width. Btw, those black spots you see are part of the design. It's just the white crust that's of concern.
