Network Calathea (network plant) care

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness network calathea grows fastest in. Bright, filtered light suits the mosaic patterning; an east window or a few feet back from a south/west window is ideal. Direct midday sun scorches and fades the fine network into bleached patches. You'll know it's right when new leaves come out the same size and colour as the established ones. Smaller, paler new leaves = move closer to the window.

Watering

Aim for when the top 2-3 cm of soil is dry, roughly every 5-7 days for network calathea, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Keep the mix lightly, evenly moist but never waterlogged. Use distilled water, rainwater, or filtered water — fluoride and chlorine in tap water brown the leaf edges. Reduce frequency in winter.

Soil and pot

Network Calathea grows best in light, moisture-retentive aroid-style mix. Blend peat or coir with perlite and a little orchid bark for drainage that still holds moisture. Aim for a slightly acidic, free-draining medium; never let roots sit in a saturated pot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Network Calathea sits happiest at around 60-80% humidity and 18-27°C (65-80°F). One of the thirstier prayer plants for ambient moisture. Crispy edges signal air that is too dry — group with other plants, use a pebble tray, or run a humidifier rather than relying on misting alone. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed network calathea sparingly. Feed monthly through spring and summer with a balanced houseplant fertiliser at half strength. Marantaceae are salt-sensitive — flush the pot occasionally and pause feeding in autumn and winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on network calathea in the Growli community. Each is annotated with the most common cause so you know where to start.

• Brown, crispy leaf edges — Caused by low humidity or mineral/fluoride build-up from tap water. Switch to distilled or rainwater and raise ambient humidity.
• Faded or scorched mosaic pattern — Too much direct sun bleaches the fine network. Move to bright indirect light.
• Curling, limp leaves — Usually underwatering or cold, dry air; check that the top of the mix has not dried out completely.
• Spider mites — Dry indoor air invites mites under the leaves. Inspect regularly, rinse foliage, and treat with insecticidal soap.

Propagation

Propagate by division at repotting in spring — separate a clump with its own roots and crown and pot up. Stem cuttings do not root reliably in prayer plants. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Network Calathea is pet-safe. ASPCA-listed as non-toxic to cats and dogs; the prayer plant genera Calathea/Goeppertia (Marantaceae) carry no toxic principles. Non-toxic does not mean edible — large quantities of any foliage may cause mild, transient stomach upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
