About Maranta Bicolor
Maranta bicolor · also called two-colour prayer plant, bicolor prayer plant · houseplant
Maranta bicolor is a compact prayer plant with rounded blue-green leaves marked by dark green blotches along the midrib and purple-tinged undersides. Slightly tougher than the red-veined maranta, it folds its leaves upright at night. A low, spreading tabletop or hanging plant, it wants warmth, even moisture, soft water and good humidity to keep its markings sharp.
Preferred mix: Light, moisture-retentive peat-free mix
Watch for — Curling leaves: Indicates underwatering or low humidity. Keep the soil evenly moist and move away from drafts and heat sources.
Why maranta bicolor needs this mix
Maranta Bicolor hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Maranta Bicolor 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 maranta bicolor 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 maranta bicolor — 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 maranta bicolor dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for maranta bicolor?
Maranta Bicolor 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 maranta bicolor 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 maranta bicolor'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 maranta bicolor covers the timing and technique step by step.
