Also called aglaonema, silver evergreen, Philippine evergreen.

About Chinese evergreen

Aglaonema commutatum · also called aglaonema, silver evergreen · tropical

Chinese evergreen is a patterned-leaf aroid from Southeast Asia that handles low light better than almost any other variegated houseplant. Modern hybrids come in pink, red, and silver, all sharing the same easy-going temperament. Mildly toxic to pets.

Aglaonema (Chinese evergreen) is native to the tropical and subtropical rainforest understory of Asia and New Guinea, growing in warm, humid shade beneath the forest canopy with consistently moist soil.

It wants a rich but free-draining, peat-based mix that stays lightly moist, mirroring the humus-rich, well-aerated rainforest floor.

Mature size: 45-90 cm tall and wide

How to tell chinese evergreen needs repotting

Repotting on a calendar is less reliable than reading the plant. For chinese evergreen, 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 chinese evergreen leaves are noticeably smaller than older ones despite good light.

How often to repot chinese evergreen

Every 12–18 months — sooner if roots show fast. Chinese evergreen's growth habit — clumping or bushy evergreen — sets the pace. Chinese evergreen is a patterned-leaf aroid from Southeast Asia that handles low light better than almost any other variegated houseplant. Modern hybrids come in pink, red, and silver, all sharing the same easy-going temperament. Mildly toxic to pets.

What size pot to step chinese evergreen up to

Step up one pot size — about 2–3 cm (an inch) wider. Chinese evergreen 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 chinese evergreen

Early spring, just as new growth restarts, is the ideal window for chinese evergreen. 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 chinese evergreen

Time it for spring. Repot chinese evergreen 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 chinese evergreen out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh free-draining houseplant 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 chinese evergreen 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 chinese evergreen

Chinese evergreen wants free-draining houseplant mix. Standard potting compost with added perlite. Repot every 2 years. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting chinese evergreen — frequently asked questions

How often should you repot chinese evergreen?

Every 12–18 months — sooner if roots show fast for chinese evergreen. Repot chinese evergreen 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 free-draining houseplant mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does chinese evergreen need?

When is the best time of year to repot chinese evergreen?

Can you put chinese evergreen straight into a much bigger pot?

No. Even a fast-growing chinese evergreen 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 chinese evergreen after repotting?

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