How to Increase Humidity
I live in a place which is quite hot in summer. I have lots of potted plants on my balcony. Is it a good idea to put a bed of pebbles on the pots to prevent loss of humidity for plants that are vulnerable to heat?

Yes, placing a layer of mulch on top of the soil, whether it be pebbles or wood chips, will help keep moisture in the soil. You can also place the plants on a tray filled with pebbles and water, and this will help increase the humidity around the plant.
