Plant Care

With leaves that look hand-painted in electric pink, white, or red against deep emerald green, the nerve plant is one of the most visually striking small houseplants you can own. It's also, frankly, one of the most demanding. But once you understand exactly what Fittonia wants — and why — keeping it thriving becomes straightforward. This complete nerve plant care guide covers everything: light, watering, humidity, soil, propagation, troubleshooting the signature "dramatic wilt," and the most beautiful Fittonia varieties available today. Whether you're a first-time Fittonia parent or trying to revive a struggling plant, this guide has you covered. What Is a Nerve Plant? (Fittonia Overview) Nerve plants belong to the genus Fittonia, in the family Acanthaceae. They're native to the tropical rainforest floors of Peru and other parts of South America, where they grow as low, spreading ground cover in the humid understory — under a dense canopy with filtered light, consistently moist soil, and near-constant high humidity. That origin story explains everything about their care requirements. They evolved to thrive in low light, high humidity, and consistently moist — but well-drained — soil. Replicate that environment indoors, and Fittonia flourishes. Common names include nerve plant, mosaic plant, and painted net leaf. The "nerve plant" name refers to the intricate network of colored veins that patterns every leaf — a feature that makes them look almost too beautiful to be real. Nerve Plant Varieties: Which Type Should You Choose? The Fittonia genus offers remarkable variety despite being a relatively small genus. The key differences are vein color and leaf size: Variety Vein Color Leaf Size Notes Fittonia albivenis 'Frankie' Deep rose/pink Medium Most popular variety; vivid coloring Fittonia albivenis 'White Anne' White/cream Medium Elegant, classic look Fittonia albivenis 'Red Anne' Deep red Medium Most dramatic contrast Fittonia albivenis 'Mini Superba' White Very small Miniature form; ideal for terrariums Fittonia albivenis 'Pink Star' Pink with star pattern Small-medium Lighter green base; unique pattern Fittonia gigantea Deep red/pink Large Larger-leafed species; rarer All varieties share essentially the same care requirements. The choice comes down to the color scheme you prefer for your space. Browse our Fittonia collection to see which varieties are currently available. Light Requirements: What Nerve Plants Actually Need Fittonia is one of the few houseplants that genuinely thrives in low to medium indirect light. In their native habitat, they grow under the forest canopy with no direct sun whatsoever. This makes them exceptional plants for rooms that don't get much natural light. Ideal Light Conditions Best: Bright indirect light filtered through a sheer curtain (north or east window) Acceptable: Medium indirect light — 3–5 feet from an east or north window Will survive: Low light areas where few plants succeed Avoid: Direct sun of any kind, which causes leaf scorch and bleaching Signs of too much light: Washed-out, faded vein colors; pale, dry-looking leaves; brown or white scorched patches. Signs of too little light: Slow or no growth; small new leaves; vein colors becoming less vivid. If this happens, move slightly closer to a light source — but avoid direct sun. Nerve plants are excellent choices for low-light spaces that need color and visual interest. They work particularly well alongside other low-light plants like peace lilies and pothos. Watering Nerve Plants: Consistent Moisture Is Key Watering is where most Fittonia owners struggle. The plant has two opposing failure modes: dramatic wilting from underwatering, and root rot from overwatering. Understanding the middle ground is the key to success. The Nerve Plant Watering Goal You want soil that stays consistently moist — never soggy, never bone dry. Think of a wrung-out sponge: damp throughout, but not dripping. The top of the soil should feel moist to the touch, but the pot should never feel heavy with standing water. Watering Frequency In most indoor conditions, this means watering every 5–7 days in spring and summer, and every 7–10 days in autumn and winter. But frequency is less important than the actual soil moisture — always check before watering. Test by pressing your finger 1 inch into the soil. If it feels barely moist or dry, water thoroughly. If it still feels damp, wait another day or two and check again. How to Water Water thoroughly from the top, allowing water to run out of the drainage holes. Empty the saucer after 30 minutes — nerve plants must never sit in standing water. Use room-temperature water; cold water stresses these tropical plants. If your tap water is heavily chlorinated or fluoridated, let it sit overnight to off-gas before using it. Nerve plants can be sensitive to fluoride, which causes brown leaf tips. Understanding the Dramatic Wilt The nerve plant's most famous behavior is its sudden, alarming collapse when underwatered. The entire plant will droop dramatically, looking like it's about to die — sometimes within just a few hours of drying out. The good news: It almost always recovers fully within 20–30 minutes of watering. This bounce-back is so reliable that some experienced Fittonia growers use the wilt as a watering indicator. However, repeatedly allowing the plant to reach this stress point weakens it over time and makes it more susceptible to pests and disease. Aim to catch it before the wilt happens. Humidity: The Single Most Important Factor If there's one non-negotiable for nerve plants, it's humidity. Fittonia demands consistently high humidity — ideally 60–80% relative humidity — to look its best. In average home conditions (30–50% RH), Fittonia struggles. In low-humidity homes with central heating or air conditioning running, it deteriorates fast. Signs of inadequate humidity: Brown, crispy leaf edges — the first warning sign Leaf tips dying back Frequent wilting even when soil is moist Leaves curling inward Best Ways to Increase Humidity for Nerve Plants Humidifier (recommended): A small cool-mist humidifier near your plant is the most reliable solution. Set to maintain 60%+ RH in the plant's immediate area. Terrarium or enclosed glass container: Nerve plants are one of the absolute best terrarium plants. The enclosed environment maintains near-100% humidity, perfectly mimicking the rainforest floor. Browse our terrarium collection for compatible companion plants, and see our complete terrarium building guide for setup instructions. Fittonia is hands-down one of the most popular terrarium plants for this reason. Pebble tray: Fill a tray with pebbles, add water below the pebble surface, and sit the pot on top. Provides moderate humidity improvement in the immediate area. Bathroom placement: A bathroom with natural light and regular shower steam is a natural high-humidity zone. Many plant parents keep their Fittonia in the bathroom year-round. See our best bathroom plants guide for compatible companions. Plant grouping: Grouping plants together increases local humidity through transpiration. Place Fittonia alongside other moisture-loving plants like calatheas, prayer plants, and ferns for a shared humidity microclimate. For a comprehensive breakdown of indoor humidity management, humidity levels by plant type, and tools to measure RH accurately, read our complete indoor humidity guide. Temperature Nerve plants prefer consistently warm temperatures: 60–80°F (16–27°C). They are frost-intolerant and should never be exposed to temperatures below 55°F (13°C). Key things to avoid: Cold drafts from windows, doors, or air conditioning vents Sudden temperature drops Placement near heating vents (too dry and too hot) In most heated homes, temperature is rarely the issue — it's humidity and watering that present challenges. Soil: Well-Draining but Moisture-Retentive Nerve plants need soil that balances two goals: holding enough moisture to stay consistently damp, while draining well enough to prevent waterlogging. Standard potting mix alone is often too dense and poorly draining for Fittonia. Recommended Soil Mix Component Ratio Purpose Peat moss or coco coir 50% Moisture retention, light texture Perlite 30% Drainage, aeration, prevents compaction Fine orchid bark or pumice 20% Drainage channels, root aeration If mixing your own isn't practical, a high-quality African violet mix is a good commercial alternative — it's lightweight, moisture-retentive, and well-aerated. You can also start with a quality indoor potting mix and add a generous amount of perlite (around 30%) to improve drainage. Ensure your pot has drainage holes — this is non-negotiable for Fittonia. Root rot from waterlogged soil is the plant's #1 killer. Pot Selection For nerve plants, plastic or glazed ceramic pots are often better than terracotta. Terracotta's porous walls wick moisture away from the soil — useful for drought-tolerant plants, but counterproductive for moisture-loving Fittonia. Plastic or glazed pots retain moisture longer, reducing how often you need to water. Keep pots relatively small — Fittonia prefers a snug root zone and is slow to outgrow its container. Fertilizing Nerve Plants Nerve plants are light feeders. Over-fertilizing is more harmful than under-fertilizing and causes salt buildup that burns roots and turns leaf edges brown. Fertilizing schedule: Spring and summer (active growth): once a month with a balanced liquid fertilizer diluted to half strength Fall and winter: stop fertilizing entirely If you notice white crusty deposits on the soil surface — a sign of fertilizer salt buildup — flush the soil with plain water until it runs clear through the drainage holes. Then skip a month before fertilizing again. Repotting Nerve Plants Nerve plants grow slowly and don't need frequent repotting. Move up one pot size only when roots are visibly emerging from drainage holes or circling the inside of the pot — typically every 2–3 years. Spring is the best time to repot. Choose a pot only 1–2 inches larger in diameter than the current one. Use fresh soil mix and water thoroughly after repotting. Expect a brief adjustment period of slower growth as the plant settles into its new container. For step-by-step repotting instructions, see our complete repotting guide. How to Propagate Nerve Plants Nerve plants are among the easiest houseplants to propagate from stem cuttings. This makes them great for filling in a terrarium, sharing with friends, or multiplying your collection. Stem Cutting Propagation (Best Method) Take a cutting: Using clean scissors, cut a stem 2–3 inches long with at least 2 leaf nodes (the points where leaves attach to the stem). Prepare the cutting: Remove the bottom leaves, leaving 2–3 leaves at the top. Root in water or soil: Place in a small glass of room-temperature water (changing it every few days), or plant directly in moist propagation mix. In water, roots appear in 1–2 weeks. In soil, roots establish in 2–3 weeks. Maintain humidity: Cover the cutting with a clear plastic bag or dome to maintain high humidity during rooting. This is especially important if propagating in soil. Transplant: Once roots are 1–2 inches long (water propagation) or the cutting shows signs of new growth (soil propagation), transplant to a small pot with your standard Fittonia mix. For terrarium use, cuttings can often be planted directly into the terrarium's established substrate — the high humidity environment does the work. See our complete propagation guide for detailed techniques across all methods. Common Nerve Plant Problems and How to Fix Them Wilting Cause Diagnosis Fix Underwatering Soil is dry; plant perks up within 30 min of watering Water thoroughly; increase watering frequency Root rot (overwatering) Soil is soggy; plant stays wilted after watering; mushy stems Remove from pot, trim rotted roots, repot in fresh dry mix Cold/draft stress Plant near cold window or vent; wilts without soil being dry Move to warmer, draft-free location Brown Leaf Edges Most likely cause: Low humidity. Move plant to a more humid location, add a humidifier, or place in a terrarium. Also check for fluoride sensitivity — if using tap water, switch to filtered or let tap water sit overnight. Yellow Leaves Most likely cause: Overwatering or too much direct light. Check soil moisture and adjust watering. Ensure the plant is in indirect light only. See our yellow leaves guide for a complete diagnostic. Leggy, Stretched Growth Cause: Insufficient light. The plant stretches toward light, producing long stems with widely spaced leaves. Move closer to a light source. Pinch back leggy stems to encourage bushier growth. Faded Vein Color Causes: Too much direct sun (causes bleaching) or too little light (reduces color intensity). Move away from direct sun, or if in a very dark location, increase light slightly. Pests Nerve plants are susceptible to spider mites (in dry conditions) and mealybugs. Check leaf undersides and stem joints regularly. Treat spider mites with increased humidity and neem oil spray. Remove mealybugs with alcohol-dipped cotton swabs and follow up with neem oil. Isolate any infested plant immediately. Nerve Plants in Terrariums: The Perfect Match If you want the most effortless Fittonia experience possible, grow them in a terrarium. The enclosed environment naturally provides everything nerve plants need: consistently high humidity, stable temperatures, and protection from drafts. In a well-established terrarium, Fittonia rarely wilts and its vein colors stay vivid and saturated. Best terrarium companions for Fittonia: Mosses (Java moss, sheet moss) — love the same conditions Mini peperomias — compact, same humidity needs Polka dot plant (Hypoestes) — colorful companion with similar requirements Mini ferns — natural rainforest floor companions Miniature orchids — same humidity requirements Avoid mixing with succulents or cacti — their care requirements are opposite to Fittonia's.

Yes! Fittonia is non-toxic to cats, dogs, and humans — making it a great choice for pet-friendly homes. If you're building a pet-safe indoor garden, nerve plants combine well with other pet-friendly houseplants from our collection. Our non-toxic plants for cats guide and pet-safe houseplants guide cover the full range of safe options. Frequently Asked Questions Is nerve plant hard to care for? Nerve plants have a reputation for being challenging, but it comes down to two factors: humidity and consistent watering. If you can provide high humidity (60%+) and check soil moisture frequently, Fittonia is very rewarding. A terrarium environment removes most of the challenge entirely. Why does my nerve plant keep wilting? The most common cause is underwatering — nerve plants wilt very dramatically when they dry out. Check soil moisture first. If the soil is already moist or soggy and the plant is still wilting, suspect root rot from previous overwatering. The plant should perk up within 30 minutes of watering if underwatering is the cause. Can nerve plants grow in low light? Yes — Fittonia is one of the best options for low-light spaces. They evolved on the rainforest floor with very little direct light. Avoid direct sun, which burns their leaves. See our best low-light plants guide for companion plants that share their requirements. How often should I water my nerve plant? Every 5–7 days in spring/summer, and every 7–10 days in fall/winter — but always check soil moisture first. The goal is consistently moist soil, not a fixed schedule. Can I grow nerve plant outside? Nerve plants can grow outdoors in USDA zones 11–12 (consistently frost-free tropical climates). In cooler zones, they can be grown outdoors in summer in shaded, sheltered spots, but must come inside before temperatures drop below 55°F. How do I make my nerve plant bushy? Pinch off the growing tips regularly to encourage branching. When you see the plant starting to get leggy (long stems with few leaves), pinch back to a leaf node. The plant will send out two new stems from that point, creating denser, bushier growth. Do nerve plants flower? Yes, though the flowers are small and considered unremarkable — tiny white or yellow spikes that most growers remove because they divert energy from foliage. Pinching off flower spikes keeps the plant focused on producing the stunning leaf display it's grown for. Where to Buy Nerve Plants Fittonia are widely available, but quality varies significantly. When buying, look for plants with fully saturated vein colors, firm stems, and no yellowing or brown edges — these indicate the plant has been grown in adequate humidity and light. Browse our Fittonia collection for healthy, well-established nerve plants. We also carry companion plants perfect for creating a Fittonia terrarium — explore terrarium plants or shop our bestsellers to build your collection. The nerve plant's combination of stunning visual drama, compact size, and genuine low-light adaptability makes it one of the most rewarding small houseplants available — as long as you give it the humidity it craves. Set up the right environment once, and Fittonia will reward you with color and growth for years.

How to Build a Terrarium: A Complete Beginner's Guide There's something magical about a terrarium — a self-contained little world of lush greenery, living right on your desk or windowsill. Whether you've been eyeing those gorgeous glass jars on Pinterest or you want a creative weekend project that doubles as living home décor, building your own terrarium is easier than you think. At Divine Roots Botanicals, we grow many of the perfect plants for terrariums, and in this guide, we'll walk you through every step — from choosing your container to planting, decorating, and keeping your miniature garden thriving for years. What Is a Terrarium? A terrarium is a miniature garden housed inside a glass or transparent container. Think of it as a tiny, portable ecosystem. The concept has been around since the 1800s, when a London doctor named Nathaniel Bagshaw Ward accidentally discovered that ferns and mosses could thrive inside sealed glass cases. Today, terrariums are one of the hottest trends in indoor gardening — and for good reason. They're beautiful, low-maintenance, and perfect for small spaces like apartments, dorm rooms, and offices. There are two main types of terrariums, and understanding the difference is the single most important decision you'll make before you start building. Closed Terrariums A closed terrarium has a lid or stopper that seals the container. Inside, a self-sustaining water cycle develops: moisture evaporates from the soil and plants, condenses on the glass walls, and drips back down — just like rain in a tiny ecosystem. Closed terrariums are ideal for tropical, humidity-loving plants like Fittonia (nerve plants), mosses, and small ferns. Once established, they can go weeks or even months without watering. Open Terrariums An open terrarium has no lid, allowing air to circulate freely. This creates a drier environment that's perfect for succulents, cacti, and other plants that prefer less humidity. Open terrariums require more frequent watering than closed ones, but they're incredibly forgiving and a fantastic choice for beginners. Gathering Your Materials: Everything You Need Before you get your hands dirty, let's gather everything you need. The beauty of terrarium building is that you don't need fancy or expensive supplies — just the right layers in the right order. The Container Almost any clear glass container can become a terrarium. Here are some popular options: Glass jars — Mason jars, apothecary jars, or cookie jars (great for closed terrariums) Fish bowls — Classic round bowls work beautifully for open terrariums Geometric terrariums — Trendy hexagonal or diamond-shaped glass containers Wardian cases — The traditional terrarium shape, like a miniature greenhouse Large glass bottles or demijohns — For a stunning conversation piece The key is clear glass (so light can reach the plants) and a wide enough opening that you can comfortably get your hands inside — at least for your first build. The Layers A terrarium isn't just soil in a jar. It's a carefully structured system with distinct layers that work together to keep your plants healthy. Here's what you need: Drainage layer: Small pebbles, gravel, or expanded clay balls (LECA) — about 1–2 inches deep Separation layer: A thin piece of activated charcoal or sphagnum moss to prevent soil from settling into the drainage layer and to filter the water Activated charcoal: A sprinkle of horticultural charcoal keeps water fresh and prevents mold and odor — especially important in closed terrariums Substrate (soil): A well-draining potting mix appropriate for your plant type Decorative elements: Small stones, driftwood pieces, miniature figurines, or preserved moss for the finishing touches The Plants This is the fun part. We'll cover the best plant choices in detail below, but the golden rule is: choose plants that share the same environmental needs. Don't mix succulents (which hate humidity) with ferns (which love it) in the same container. Tools Long tweezers or chopsticks (for positioning plants in tight spaces) A small spoon or funnel (for adding soil neatly) A spray bottle (for watering and cleaning the glass) Paper towels (for wiping down the inside of the glass) Step-by-Step: Building Your First Terrarium Ready to build? Follow these steps and you'll have a finished terrarium in about 30 minutes. Step 1: Clean Your Container Wash your glass container thoroughly with warm soapy water and dry it completely. Any residue or bacteria on the glass can encourage mold growth down the road. This is a small step that makes a big difference. Step 2: Add the Drainage Layer Pour 1–2 inches of small pebbles, gravel, or LECA into the bottom of the container. This layer is critical because terrariums don't have drainage holes. Without it, water would pool at the bottom, drown the roots, and cause root rot. The drainage layer gives excess water somewhere to go, away from your plant's roots. Step 3: Add the Charcoal Layer Sprinkle a thin, even layer of activated horticultural charcoal over the drainage stones. This acts as a natural filter — it absorbs impurities, prevents bacterial growth, and keeps your terrarium smelling fresh. For closed terrariums, this layer is non-negotiable. For open terrariums, it's still highly recommended. Step 4: Add a Separation Barrier Place a thin layer of sphagnum moss or a piece of fine mesh screen on top of the charcoal. This barrier prevents your potting soil from sifting down into the drainage layer over time, which would defeat its purpose. Step 5: Add the Soil Add 2–3 inches of potting mix (the amount depends on your container size and plant root depth). For tropical closed terrariums, a standard indoor potting mix works well. For succulent open terrariums, use a well-draining cactus/succulent mix. Use a spoon or funnel to add the soil neatly — try to keep it off the glass walls for a cleaner look. Pro tip: Create small hills and valleys in the soil for a more natural, landscape-like appearance rather than a flat surface. Step 6: Plant Your Plants Now the creative part begins. Before placing anything permanently, arrange your plants on the table outside the container first to plan your layout. Consider: Place taller plants in the back (or center, if the terrarium will be viewed from all sides) Use shorter, spreading plants like Fittonia around the edges Leave some space between plants — they'll grow! Odd numbers (3 or 5 plants) tend to look more natural than even groupings Gently remove each plant from its nursery pot, shake off excess soil, and use your fingers or long tweezers to nestle the roots into the terrarium soil. Press the soil firmly around the base of each plant to secure it. Step 7: Decorate This is where your terrarium goes from "garden project" to "art piece." Add decorative elements like: Small river stones or colored pebbles Pieces of driftwood or bark Preserved sheet moss to cover exposed soil Miniature figurines (tiny animals, fairy garden accessories, or small stones) Step 8: Water and Clean Give your new terrarium a light misting with a spray bottle. For closed terrariums, you want the soil to be damp but not soggy — err on the side of too little water. You can always add more, but removing excess from a sealed container is tricky. For open terrariums, water lightly around the base of each plant. Use a damp paper towel wrapped around a chopstick to wipe any soil smudges off the inside of the glass. A clean container lets the light in and shows off your plants beautifully. The Best Plants for Terrariums Not every houseplant belongs in a terrarium. You need plants that stay small, tolerate the unique terrarium environment, and play well with neighbors. Here are our top recommendations — all of which we grow and ship at Divine Roots.

Read our Sempervivum care guide. Caring for Your Terrarium: What to Expect One of the biggest advantages of terrariums is how little maintenance they need — but "low maintenance" doesn't mean "no maintenance." Here's how to keep your miniature garden happy. Watering Closed terrariums: After the initial watering, you may not need to water again for weeks or even months. Watch for condensation on the glass — a light fog is normal and healthy. If the glass is completely covered in heavy droplets and you can't see inside, open the lid for a few hours to let excess moisture escape. If the soil looks dry and there's no condensation at all, add a small amount of water with a spray bottle. Open terrariums: Check the soil every 1–2 weeks. Water sparingly when the top layer of soil feels dry. For succulent terrariums, less is always more — overwatering is the number one killer. If you're not sure whether to water, wait another few days. Light Place your terrarium in bright, indirect light. Near a north or east-facing window is ideal. Avoid direct sunlight — the glass acts like a magnifying glass and can cook your plants. If your space is low on natural light, a small LED grow light works beautifully. Pruning As your plants grow, they may start to outgrow their space. This is a good sign! Use small scissors or tweezers to trim back any plants that are pressing against the glass or crowding their neighbors. Regular pruning keeps the terrarium looking tidy and prevents one aggressive grower from taking over. Troubleshooting Common Problems Mold or fungus: Remove the affected area immediately with tweezers. Open the lid (if closed) for better air circulation. Reduce watering. A sprinkle of cinnamon powder (a natural antifungal) on the soil surface can help. Yellowing leaves: Usually a sign of overwatering. Check our guide on why plant leaves turn yellow for more detailed troubleshooting. Foggy glass (closed terrarium): Some condensation is normal. Heavy, persistent fog means too much moisture — open the lid for a few hours. Leggy, stretched plants: Not enough light. Move the terrarium closer to a light source. Pests: Fungus gnats are the most common terrarium pest. Allow the top layer of soil to dry between waterings to discourage them, or add a thin layer of decorative sand on top.

A well-maintained terrarium can last for years — even decades. The world's oldest known terrarium was sealed in 1960 and was still thriving over 50 years later. Closed terrariums are particularly long-lived because they create a self-sustaining water cycle. The key to longevity is starting with the right plants, proper layering, and occasional maintenance like pruning and mold removal. Can I use regular potting soil in a terrarium? For tropical closed terrariums, a standard indoor potting mix works well. For succulent open terrariums, use a specialized cactus and succulent mix that drains quickly. Avoid soil with added fertilizer (marked "feeds for 6 months") as the enclosed environment can cause fertilizer salts to build up. For the best results, check our complete guide to potting mixes. Do terrariums need sunlight? Terrariums need bright, indirect light — not direct sunlight. The glass walls act like a greenhouse and amplify heat, which can literally cook your plants in direct sun. A spot near a north or east-facing window is ideal. If you don't have good natural light, a small LED grow light set on a timer for 10–12 hours works perfectly. Why is my closed terrarium fogging up? Light condensation on the glass is completely normal and actually a sign of a healthy water cycle. If the fog is so thick you can't see inside, the terrarium has too much moisture. Simply remove the lid for a few hours to let excess humidity escape, then reseal. Over time, you'll find the right balance. Can succulents go in a closed terrarium? No — succulents need dry, well-ventilated conditions and will quickly develop rot in the humid environment of a closed terrarium. Always use an open, lidless container for succulents and cacti. For tropical plants that love humidity (like Fittonia, ferns, and mosses), closed terrariums are the way to go. How often should I water my terrarium? For closed terrariums, you may only need to water every few weeks to a few months — watch the condensation level as your guide. For open terrariums, check the soil every 1–2 weeks and water sparingly when dry. The number one mistake new terrarium owners make is overwatering. When in doubt, wait.

How to Care for Fittonia: The Complete Guide Fittonia — the Nerve Plant — is a tiny powerhouse of color and drama. Its intricate vein patterns in pink, red, white, and silver make it look like miniature living art. And yes, it's famously dramatic — fainting completely when thirsty and reviving within hours of watering. Here's how to keep your Nerve Plant happy. Fittonia at a Glance Botanical Name Fittonia albivenis Common Names Nerve Plant, Mosaic Plant, Fittonia Plant Type Tropical creeping perennial Mature Size 3–6 inches tall, 12–18 inch spread Light Low to medium indirect Water Keep consistently moist Humidity 60–80% (high humidity preferred) Temperature 65–80°F (18–27°C) Soil Moisture-retentive, well-draining Toxicity Non-toxic to pets Difficulty Easy to moderate Light Requirements Fittonias prefer low to medium indirect light. Their thin leaves scorch easily in bright light. They're excellent desk plants, bathroom plants, and terrarium residents. Medium indirect: Ideal. Vibrant vein colors and compact growth. Low light: Handles it well. One of the better truly low-light plants. Bright indirect: Acceptable but keep away from direct sun. Direct sun: Burns leaves quickly. Watering Keep the soil consistently moist — never let it dry out completely. Fittonias are dramatic communicators: they collapse flat when thirsty and recover within hours of watering. Water when the top of the soil starts to feel dry Spring/Summer: Every 3–5 days Fall/Winter: Every 5–7 days While they recover from wilting, repeated severe droughts stress the plant Humidity This is Fittonia's biggest requirement: 60–80% humidity. They thrive in humid conditions and struggle in dry air. Best humidity solutions: Terrariums — Fittonias are one of the best terrarium plants. Enclosed glass creates the perfect humid microclimate. Bathrooms — Natural humidity from showers Humidifiers — Most reliable for open-room growing Grouping — Cluster with other plants for shared humidity Temperature & Soil Keep in 65–80°F. Avoid cold drafts. Use moisture-retentive soil: 2 parts peat/coco coir + 1 part perlite. Fertilizing Feed monthly during spring/summer with balanced liquid fertilizer at quarter strength. Fittonias have delicate roots — less is more. Propagation Stem cuttings root easily in water or moist soil. Take a 3–4 inch cutting with at least 2 nodes. Roots develop in 1–2 weeks. Division works well too — separate clumps during repotting. Common Problems Dramatic Wilting Underwatering. Water immediately and the plant recovers within hours. Keep soil consistently moist to prevent repeat episodes. Crispy Brown Edges Low humidity. Boost humidity or move to a terrarium environment. Leggy Growth Needs more light. Also pinch growing tips to encourage bushy, compact growth. Fittonia is completely non-toxic to cats and dogs — a top choice for pet-safe homes. 👉 Shop Fittonia Skeleton · Shop Red Flame · Shop Terrarium Bundle (4 plants) Frequently Asked Questions Why does my Fittonia keep fainting? It's drying out between waterings. Keep soil consistently moist. Fittonias in terrariums rarely wilt because the enclosed environment maintains steady moisture and humidity. Are Fittonias good terrarium plants? They're among the very best! Their compact size, love of humidity, and tolerance of low light make them ideal terrarium residents. Our Terrarium Builder Bundle includes 4 assorted varieties. Are Fittonias pet-safe? Yes! Fittonias are non-toxic to cats, dogs, and children.
