Prayer plants · needs attention to keep

Last updated 26 October 2026

Calathea Network (Goeppertia musaica) wants medium indirect light; never direct sun. Water it every 5 days. Keep evenly damp — never soggy, never dry — and use rainwater or filtered water if you can. Tap water is the most common cause of the brown edges this family is famous for. Pot it in peat-free compost with perlite, moisture-retentive but not heavy. A balanced feed at quarter to half strength monthly in spring and summer. They are sensitive to over-feeding, and repot once a year. Humidity: above 60%. Below that, the edges brown and it will not stop. The ASPCA lists its genus as non-toxic to cats and dogs.

Calathea 'Network': bright-green leaves covered in a fine mosaic of pale lines, like a net. Noticeably tougher than most calatheas, and better at coping with ordinary room humidity.

Watering a Calathea Network

Water every 5 days. Keep evenly damp — never soggy, never dry — and use rainwater or filtered water if you can. Tap water is the most common cause of the brown edges this family is famous for.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Medium indirect light. Calatheas — which is what most of these were called until the genus was split, and what everyone still calls them — burn in direct sun and lose their markings in a dark corner.

Humidity and temperature

Above 60%. Below that, the edges brown and it will not stop. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

A light, moisture-retentive mix — compost with perlite and a little bark. The roots are fine and shallow, so a wide shallow pot beats a deep one.

Feeding

A balanced feed at quarter to half strength monthly in spring and summer. They are sensitive to over-feeding. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot once a year. Every spring, into a shallow pot. Divide the clump at the same time if it has spread.

Common problems

Brown crispy edges on every leaf
Dry air, or minerals in tap water. Usually both.

Fix: Get the humidity above 60% and switch to rainwater or filtered water. Existing damage will not heal.

Brown tips and edges: how to read it on any plant
Leaves curling inward
Thirsty, or the air is too dry.

Fix: Water and raise the humidity; the leaves uncurl within a day if that was it.
Leaves staying folded up all day
Stress — too dry, too cold, or too dark.

Fix: The folding is normal at night. All day means something is wrong: check water, warmth and light in that order.
Fine webbing under the leaves
Spider mites, which love this family.

Fix: Shower the plant and treat weekly for a month; raise the humidity or they return.

Propagation

Divide the clump at repotting, giving each piece roots and several leaves. Stem cuttings with a node also root in water.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Non-toxic to cats and dogs, which is much of their appeal.

The ASPCA lists Calathea (Calathea spp.), the genus as a whole, as non-toxic to cats and dogs (checked 26 October 2026).

If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.

This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.

Questions people ask

How often should you water a Calathea Network?

Water every 5 days as a starting point — that is the cadence PlantParlour sets for Goeppertia musaica. Keep evenly damp — never soggy, never dry — and use rainwater or filtered water if you can. Tap water is the most common cause of the brown edges this family is famous for. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.

How much light does a Calathea Network need?

Is Calathea Network toxic to cats and dogs?

Non-toxic to cats and dogs, which is much of their appeal. The ASPCA lists Calathea (Calathea spp.), the genus as a whole, as non-toxic to cats and dogs (checked 26 October 2026). If a pet has eaten part of a plant, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 straight away.
