How to Repot a ZZ Plant

Every 2–3 years — ZZ rarely outgrows its pot. Best time: Spring or early summer. New pot size: 1–2 inches — ZZ likes being snug; oversized pots cause rhizome rot.

Frequency
Every 2–3 years — ZZ rarely outgrows its pot
Best season
Spring or early summer
Pot size
1–2 inches — ZZ likes being snug; oversized pots cause rhizome rot
Soil mix
Cactus and succulent mix or standard potting mix with 30% perlite. ZZ rhizomes store water and need fast-draining soil.

Signs your ZZ Plant needs repotting

Rhizomes (potato-like underground storage organs) visible at the soil surface or bulging the pot; soil drains very fast because rhizomes have displaced it; plant is top-heavy and tips over.

Step-by-step

  1. 1
    Let soil dry completely for 7–10 days before repotting.
  2. 2
    Slide the plant out gently — the rhizomes can be brittle.
  3. 3
    Brush away soil to inspect rhizomes. Healthy rhizomes are firm and pale brown. Cut away any soft or dark sections.
  4. 4
    If dividing, separate clumps so each new pot has at least 2–3 rhizomes connected to stems.
  5. 5
    Pot in dry succulent mix at the same depth. Do not bury the top of the rhizomes.
  6. 6
    Wait 5–7 days before watering. Resume normal watering after 2 weeks.

What kills ZZ Plant after repotting

  • Repotting in wet soil — ZZ rhizomes rot if their cuts contact moisture
  • Dense potting mix — holds water and suffocates rhizomes
  • Burying rhizomes — they should sit just below the soil surface, not deep
