About Network Calathea (Calathea Musaica)

Goeppertia kegeljanii 'Network' · also called Network Calathea, Calathea Musaica · houseplant

The Network Calathea (Goeppertia kegeljanii 'Network') is a tropical prayer plant prized for leaves etched with a fine green mosaic. It needs bright indirect light, evenly moist soil, warmth, and high humidity, and is one of the easier calatheas. The ASPCA lists Calathea as non-toxic to cats, dogs, and horses, making it pet-safe.

Mature size: Around 60 cm (2 ft) tall and 60-90 cm (2-3 ft) wide indoors at maturity.

Watch for — Yellowing leaves: Most often a watering imbalance, typically overwatering or soggy soil leading to root stress. Let the top inch dry between waterings and ensure the pot drains freely.

How to tell network calathea (calathea musaica) needs repotting

Repotting on a calendar is less reliable than reading the plant. For network calathea (calathea musaica), watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for network calathea (calathea musaica)) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

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 network calathea (calathea musaica)

Only every 2–4 years, when genuinely crowded. Network Calathea (Calathea Musaica) is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Evergreen, clump-forming tropical perennial with an upright-to-bushy rosette of round-oval leaves. A relatively slow grower that produces dense foliage; it does not vine or trail. Like other prayer plants it shows mild nyctinasty, with leaves shifting slightly between day and night..

What size pot to step network calathea (calathea musaica) up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Network Calathea (Calathea Musaica) positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping network calathea (calathea musaica) into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

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 network calathea (calathea musaica)

Early spring, just as new growth restarts, is the ideal window for network calathea (calathea musaica). 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 network calathea (calathea musaica)

Confirm it actually needs it. Slide network calathea (calathea musaica) out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip network calathea (calathea musaica) out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh rich, porous, well-draining peat-based mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water network calathea (calathea musaica) again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for network calathea (calathea musaica)

Network Calathea (Calathea Musaica) wants rich, porous, well-draining peat-based mix. Use a light, moisture-retentive but free-draining houseplant mix, ideally peat- or coir-based with added perlite or vermiculite to prevent compaction and waterlogging. A pot with drainage holes is essential to avoid root rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting network calathea (calathea musaica) — frequently asked questions

How often should you repot network calathea (calathea musaica)?

Only every 2–4 years, when genuinely crowded for network calathea (calathea musaica). Only repot network calathea (calathea musaica) every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using rich, porous, well-draining peat-based mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does network calathea (calathea musaica) need?

When is the best time of year to repot network calathea (calathea musaica)?

Does network calathea (calathea musaica) like to be root-bound?

Yes — network calathea (calathea musaica) genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise network calathea (calathea musaica) after repotting?

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