Humidity

To provide extra humidity for plants at home, that thrive better in humid environments; take a shallow tray 3-4 cm deep and fill it up with gravel. Place a non-absorbing brick or a rock in the middle, making sure it is higher than the level of the gravel. Now put the potted plant on top of that brick and fill the tray with water, making sure the water level does not touch the pot. The evaporation from the shallow tray will help the plant acquire higher humidity levels needed.
