For plants that can use a steam treatment, bring them into the bathroom when you shower.

Another sign to look for is wilted foliage or curled leaves.

The saucer or tray should be at least several inches wider than the base of the plant’s pot.

Do not submerge the pebbles because the plant pot has to sit on top of dry pebbles.

If it does, remove some water.

Check Water Level Regularly and Refill

Maintain consistent humidity levels around your plant.

Refill the water in the saucer or tray as the water evaporates.

Once the droplets evaporate, the water vapor adds to the plant’s humidity level.

Pebble trays are great for increasing the humidity around a plant.
