Frequently Asked Questions

Hard water build upMost of the time a white substance on the base of your leaves is caused by hard water. Water that contains high mineral levels, particularly calcium, can leave behind this type of deposit. You should use a damp cloth to remove the mineral deposits, as there are some genera of bromeliads, those with soft leaves, that are exceptionally susceptible to leaf damage from this kind of build up. For more information on what kind of water you should be using, see our post on The Best and Worst Water for Bromeliads.

Over-fertilization can also cause a white build up at the base of the leaves. Take care to feed your bromeliad properly and flush the soil and central tank regularly to remove any excess fertilizer salt.
