When & how to repot Swiss cheese vine (Monstera adansonii)

Also called Adanson's monstera, five holes plant, Swiss cheese plant (vine type).

About Swiss cheese vine

Monstera adansonii · also called Adanson's monstera, five holes plant · tropical

Monstera adansonii is a smaller climbing aroid relative of M. deliciosa, with oval leaves perforated by oblong holes. Faster-growing and easier to keep compact than M. deliciosa. Mildly toxic to pets due to insoluble calcium oxalates.

Monstera adansonii, native to the rainforests of southern Mexico through Central and tropical South America, where it climbs tree trunks as an evergreen vine.

A loose, well-aerated aroid mix with bark suits its aggressive aerial roots, which are built to anchor onto bark rather than sit in dense potting soil.

Mature size: 1.5-2.5 m trained up a pole

How to tell swiss cheese vine needs repotting

Repotting on a calendar is less reliable than reading the plant. For swiss cheese vine, watch for these signs:

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new swiss cheese vine leaves are noticeably smaller than older ones despite good light.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot swiss cheese vine

Every 12–18 months — sooner if roots show fast. Swiss cheese vine's growth habit — climbing or trailing vine — sets the pace. Monstera adansonii is a smaller climbing aroid relative of M. deliciosa, with oval leaves perforated by oblong holes. Faster-growing and easier to keep compact than M. deliciosa. Mildly toxic to pets due to insoluble calcium oxalates.

What size pot to step swiss cheese vine up to

Step up one pot size — about 2–3 cm (an inch) wider. Swiss cheese vine grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot swiss cheese vine

Early spring, just as new growth restarts, is the ideal window for swiss cheese vine. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting swiss cheese vine

Time it for spring. Repot swiss cheese vine in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip swiss cheese vine out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh chunky aroid mix in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water swiss cheese vine once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for swiss cheese vine

Swiss cheese vine wants chunky aroid mix. Two parts compost, one part orchid bark, one part perlite. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting swiss cheese vine — frequently asked questions

How often should you repot swiss cheese vine?

Every 12–18 months — sooner if roots show fast for swiss cheese vine. Repot swiss cheese vine roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh chunky aroid mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does swiss cheese vine need?

When is the best time of year to repot swiss cheese vine?

Can you put swiss cheese vine straight into a much bigger pot?

No. Even a fast-growing swiss cheese vine should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise swiss cheese vine after repotting?

Not immediately. Wait about 4 weeks after repotting swiss cheese vine. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
