ZZ Plant 10" Pot
What makes ZZ plant such a good houseplant is that it's wonderfully tolerant to a wide range of conditions, including low light, low humidity, and periods of drought. That means it will survive just about any corner of your home, even if you only water it once every couple of weeks (it grows best, though, when watered as the top inch or two of the potting mix dries).
Lighting: ZZ plants doesn't even need natural light -- it'll thrive just fine indoors under fluorescent lights, such as those in office buildings.
Watering: As a survival technique, ZZ plant has evolved to start dropping its leaflets to conserve moisture during periods of severe drought. If you forget to water yours and see the leaflets fall, don't give up hope. Water your plant again and it should resuscitate. It's best to water ZZ plant when the top inch or so of the soil dries.
Fertilization: Fertilize ZZ plant once every six months or so with a general-purpose fertilizer labeled for use on houseplants. You can also fertilize more frequently if you want your plant to grow larger and faster.
