About Calathea Network
Goeppertia kegeljanii 'Network' · also called Calathea Network, Calathea musaica Network · houseplant
Calathea Network, the mosaic plant, has bright apple-green leaves covered in an intricate, tessellated grid of tiny rectangles like a fine net. It is one of the more forgiving calatheas but still wants warmth, high humidity and consistently moist filtered water in bright indirect light. Pet-safe, with minimal nyctinastic leaf movement compared with other prayer plants.
Preferred mix: Moisture-retentive, well-aerated mix
Watch for — Curling leaves: Underwatering or dry air causes the leaves to curl inward. Maintain even soil moisture and raise humidity to keep them flat and turgid.
Why calathea network needs this mix
Calathea Network hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Calathea Network comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons calathea network struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for calathea network — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets calathea network dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for calathea network?
Calathea Network prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for calathea network straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh calathea network's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for calathea network covers the timing and technique step by step.
