How to Repot a Monstera

Every 2–3 years for younger plants; every 3–4 years for mature plants. Best time: Late spring through early summer, when active growth resumes. New pot size: 2 inches larger in diameter — Monsteras prefer being slightly root-bound and rot in oversized pots.

Frequency
Every 2–3 years for younger plants; every 3–4 years for mature plants
Best season
Late spring through early summer, when active growth resumes
Pot size
2 inches larger in diameter — Monsteras prefer being slightly root-bound and rot in oversized pots
Soil mix
Chunky aroid mix: 40% standard potting mix + 30% orchid bark + 20% perlite + 10% horticultural charcoal. Standard potting soil compacts too much for Monstera roots.

Signs your Monstera needs repotting

Roots circling the pot bottom or growing out of drainage holes; soil drying within 2–3 days of watering; aerial roots becoming dominant; new leaves emerging significantly smaller than older ones.

Step-by-step

  1. 1
    Water thoroughly 24 hours before repotting so the rootball slides out cleanly.
  2. 2
    Slide the plant out by tipping the pot sideways. Loosen edges with a butter knife if stuck.
  3. 3
    Gently tease apart circling roots; leave the central rootball intact.
  4. 4
    Inspect for rot (dark, mushy roots smell rancid). Trim with sterile shears if found.
  5. 5
    Add 2 inches of chunky aroid mix to the new pot bottom.
  6. 6
    Center the plant; backfill with mix up to where the stem meets the roots.
  7. 7
    Tamp gently — do not compress the mix. Aroids need air pockets at the roots.
  8. 8
    Water thoroughly until water runs from the drainage hole. Skip fertilizer for 4 weeks.

What kills Monstera after repotting

  • Using standard potting soil — it compacts and suffocates Monstera roots
  • Jumping up too many pot sizes (more than 2 inches) — leads to soggy soil and root rot
  • Repotting in winter — Monsteras are dormant and recovery is slow
