Every terracotta pot on my Pune balcony gets a white-grey crust around the rim within a couple of months. Pune's water is hard, and I water by hand with a mug straight from the tap.

Does Misting Houseplants Actually Raise Humidity? What the Physics Says

Monsoon Container Drainage: Stopping Root Rot Before It Starts

I lost a snake plant to root rot in my second Pune monsoon, not because I overwatered it, but because its pot had one small drainage hole that silted shut and I never checked.
