Once winter rolls around, you can water this plant once every couple of weeks. Watering this plant too much can be very harmful to it, especially in the colder months.

If you live in a particularly dry climate, you’ll want to wet the foliage when you water the actual soil. This will help keep your plant properly hydrated so that it can remain strong and healthy.
