How to Divide a ZZ Plant Without Breaking Your Back
ZZ plants look calm. Under the soil, they are basically potatoes with goals.
Those thick rhizomes store water and energy, which is why ZZ plants survive neglect. It is also why they can be divided into multiple plants.
When to Divide
Divide when:
- The pot is crowded and roots are circling
- You have multiple stems clumping together
- You want smaller plants for different rooms
Best time: Spring through early fall.
What You Need
- A towel or old sheet (ZZ soil goes everywhere)
- Clean scissors or a knife
- Fresh potting mix plus perlite
- Pots with drainage
Step-by-Step Division
- Water lightly the day before (moist soil slides out easier)
- Lay down a towel and tip the pot on its side
- Slide the root ball out and shake off loose soil
- Find natural separation points between rhizomes
- Pull sections apart gently
- If roots are tightly tangled, cut between rhizomes with a clean knife
- Pot each division at the same depth as before
- Water once to settle soil, then wait
How Many Stems Per Pot?
- Small pot: 2 to 3 stems
- Medium pot: 4 to 6 stems
More stems looks fuller, but takes longer to dry. Do not overpack a tiny pot.
Common Mistakes
- Overwatering after division (roots are stressed)
- Using a pot with no drainage
- Upsizing too much
- Putting it in harsh sun right away
Aftercare (The First Month)
- Light: Bright, indirect light is ideal
- Water: Wait until soil is mostly dry
- Fertilizer: Skip for 4 to 6 weeks
If a stem yellows after division, do not panic. ZZ plants can drop a stem while they settle.
What To Do Next
- If you want another indestructible plant: snake plant is a good partner
- If you want to level up: try dividing a peace lily next (more drama, still doable)
