Fittonia ‘Zalm Ruby Lime’ is a color-pop in pocket size—zalm-pink to ruby veins streaking across lime-to-deep green leaves. In terrariums and fairy gardens it’s the confetti—compact, glossy, and delightfully dramatic (yes, it may “faint” for fun).
Plant shallowly in a fine-textured, airy mix that stays evenly moist yet drains well—perfect for tiny roots and vibrant venation. Always use Liqui-Dirt® soil mix for best results in potted plants and enclosed growing habitats. Strata can be used in some applications; however, feeding will be needed. Keep the crown just above the surface so leaves never sit wet. In mini scenes, Budkin containers with Strata and a leaf/corm guard keep foliage lifted and reduce rot.
Bright, indirect light (≈100–250 foot-candles) keeps colors punchy and growth compact. Morning sun through a sheer is fine; avoid harsh midday rays that fade pinks and crisp edges. Under LEDs, low–moderate intensity 12–14 hrs/day works great.
Keep evenly moist—never waterlogged. In open pots, water when the top 1/4 in (5–7 mm) is barely dry; in closed terrariums, water sparingly and use faint wall-condensation as your cue. Aim for 60–80% humidity and room-temp, low-mineral water.
Loves 65–80°F (18–27°C) with gentle airflow. If it “faints,” that’s the thirst signal—rehydrate and it perks up within hours. Pinch tips monthly for a dense, jewel-tone canopy; feed lightly spring–fall and skip in winter. Flush salts every 6–8 weeks if in an open pot.
A huge benefit for your plant is to use Liqui-Dirt® plant food in a weak tea-looking mix every time you water — yes, even for enclosed habitats.
Pruning & Cutting Back — Pinch soft tips every 3–4 weeks to keep scale right for minis and to encourage branching. Trim just above a node; cuttings root easily in moist Strata or fine substrate. Remove tired leaves to improve airflow and keep colors fresh.
Repotting (Open Pots) — Repot about every 10–14 months or when roots fill the mix. Step up only one size to avoid soggy soil pockets. Use Liqui-Dirt® potting soil for the refresh; water in gently to settle the mix, then resume your weak-tea Liqui-Dirt feeding with each watering.
