About Fittonia albivenis 'Juanita'
Fittonia albivenis 'Juanita' · also called Juanita nerve plant, Deep red nerve plant · tropical
Fittonia albivenis 'Juanita' is a bold nerve plant cultivar with large, deep green leaves traced by vivid pink-red veins that intensify in good light. A low rainforest-floor creeper from Peru, it demands constant warmth, steady moisture, and high humidity, fainting visibly when thirsty. Its larger leaves make it a striking tabletop and terrarium tropical rooting easily from cuttings.
Preferred mix: Light, moisture-retentive, free-draining peat or coir-based mix
Watch for — Sudden wilting / fainting: Indicates the soil has dried out. Water immediately and the plant typically recovers within a few hours; frequent severe wilting weakens roots over time.
Why fittonia albivenis 'juanita' needs this mix
Fittonia albivenis 'Juanita' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Fittonia albivenis 'Juanita' 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 fittonia albivenis 'juanita' 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 fittonia albivenis 'juanita' — 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 fittonia albivenis 'juanita' dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for fittonia albivenis 'juanita'?

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 fittonia albivenis 'juanita' 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.
