Whenever a friend tells me they have a "black thumb" and kill everything they touch, I always point them toward the ZZ Plant. If the Snake Plant is tough, the ZZ is practically made of iron. It’s the kind of plant that actually thrives when you forget about it for a few weeks.
In our list of 7 "Unkillable" Plants for Windowless Bathrooms, the ZZ plant earned a top spot because it handles low light like a pro. But if you want to see those stems reach their full height (they can get quite statuesque!), there are a few little secrets you should know.
Between you and me, the ZZ plant is like a camel—it’s built for survival. Let’s make sure you’re giving it the right kind of "tough love."
1. The Underground Secret: Why it Doesn't Need Much Water
If you were to peek under the soil of your ZZ plant, you’d see these thick, potato-like lumps called rhizomes. These are basically the plant’s personal water tanks.
Because it stores so much moisture underground, the quickest way to upset a ZZ is to keep the soil damp.
The Routine: I usually check my ZZ once a month. If the soil feels even slightly cool or damp, I skip it.
The Warning Sign: If the leaves start turning yellow and mushy, it’s usually a sign that it's had a bit too much to drink. If that happens, just stop watering for a few weeks and let it dry out completely.
2. Dealing with "No Light" Situations
While the ZZ plant is famous for surviving in windowless bathrooms, it still needs some energy to grow.
If your bathroom is truly pitch-black 24/7, even this tough character will eventually start to "stretch" and get leggy.
A Simple Solution: If you don't have a window, just leaving your bathroom light on for 6 to 8 hours a day is often enough.
The "Vacation" Trick: Every few months, I like to move my ZZ out to a room with a little more natural light for a week. Think of it like a little "sunshine vacation" to help it recharge its batteries before heading back to the bathroom.
3. Those Glossy Leaves: Keep the Pores Open
The ZZ plant is a champion at filtering the air, but those shiny leaves are also absolute magnets for dust. When dust builds up, the plant can't "breathe" through its pores.
Instead of using those chemical "leaf shine" products you see at the big-box stores, try this:
The Gentle Wipe: Every now and then, take a soft, damp cloth and gently wipe the dust off each leaf.
The Natural Shine: You don’t need wax to make them shine; they do that naturally when they’re clean! Keeping the leaves dust-free also helps the plant absorb every bit of light it can get in a dim room.
4. Growing a "Healthy Home"
Like the Snake Plant, the ZZ is more than just a pretty face. It’s a workhorse for your indoor air quality. It’s particularly good at removing volatile organic compounds (VOCs) like xylene and toluene from the air.
Since many of us use hairsprays or cleaners that can linger in a small bathroom, having a ZZ plant is like having a silent, green air purifier tucked into the corner.
Conclusion
If you want the "spa" look without the stress of being a full-time gardener, the ZZ plant is your best friend. It’s patient, beautiful, and incredibly forgiving. Just give it a well-draining pot, keep the watering can at bay, and it’ll be a happy member of your Zero-Waste Sanctuary for years to come.
The ZZ Plant Toolkit
Keeping things simple is the best way to care for a ZZ. Here’s what I use:
For the "Monthly Check": 3-in-1 Soil Moisture Meter. This helps you be 100% sure the soil is dry before you add more water.
The Perfect Pot: Minimalist Tapered Planter with Drainage. ZZ plants look great in something modern and sleek.
The Soil Mix: Organic Cactus & Succulent Soil. Since they have those water-storing rhizomes, they need soil that drains fast.
The Dusting Cloths: Organic Cotton Cleaning Cloths. Soft and gentle for keeping those leaves sparkling.
