About Goeppertia Medallion
Goeppertia veitchiana 'Medallion' · also called Medallion calathea, calathea medallion · tropical
The Medallion calathea is a compact prayer plant grown for its rounded, deep-green leaves brushed with a feathered pale pattern and burgundy undersides that fold upward at night. It demands warmth, steady moisture and high humidity, sulking with browning edges in dry air. Striking but fussy, it rewards stable conditions with lush, decorative foliage.
Preferred mix: Light, moisture-retentive, well-aerated mix
Watch for — Brown, crispy leaf edges: Almost always low humidity, dry soil or mineral-laden tap water. Raise humidity, keep moisture steady and switch to filtered or rainwater.
Why goeppertia medallion needs this mix
Goeppertia Medallion hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Goeppertia Medallion 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 goeppertia medallion 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 goeppertia medallion — 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 goeppertia medallion dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for goeppertia medallion?
Goeppertia Medallion 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

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 goeppertia medallion'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 goeppertia medallion covers the timing and technique step by step.
