Plant Care

Aloe vera might be the world's most recognized houseplant — and for good reason. This succulent has been cultivated for over 6,000 years for its remarkable gel, striking appearance, and near-indestructible nature. From ancient Egyptian "plant of immortality" to a modern kitchen windowsill staple, aloe vera earns its place in every home. But despite its reputation as an easy plant, aloe vera is frequently mistreated with too much water, too little light, and the wrong soil — leading to mushy rot instead of a thriving specimen. This complete aloe vera care guide covers everything you need to know to grow a spectacular, gel-packed plant indoors: light, watering, soil, humidity, fertilizing, repotting, propagation, and common problem troubleshooting. Aloe Vera at a Glance Feature Detail Scientific Name Aloe barbadensis miller Common Names Aloe vera, true aloe, medicinal aloe, burn plant Family Asphodelaceae (formerly Liliaceae) Origin Arabian Peninsula; naturalized throughout Africa, the Mediterranean, and tropical regions worldwide Growth Rate Moderate (faster in high light) Mature Size 1–3 feet tall and wide indoors Toxicity Toxic to cats and dogs; gel is safe for human topical use Difficulty Easy to intermediate (most issues come from overwatering) Aloe Vera Light Requirements: More Than You Think Here's the single biggest misconception about aloe vera: it's often described as a low-light plant. It isn't. Aloe vera is a desert succulent from the Arabian Peninsula — in its natural habitat, it basks in intense sunlight for 8+ hours a day. Indoors, it needs the brightest spot you can offer. Ideal Light for Aloe Vera Bright direct or indirect light, 6+ hours daily. A south- or west-facing windowsill is the dream location. Aloe vera will happily tolerate several hours of direct indoor sun, especially during morning or afternoon hours when intensity is lower. Full midday summer sun through glass can occasionally scorch leaves — if you notice bleached, papery patches, filter with a sheer curtain. What Happens in Low Light? In insufficient light, aloe vera reacts in predictable ways: Leaves turn pale green or yellow instead of deep green The plant becomes leggy, stretching toward any available light source Leaves thin out, losing their characteristic plump, gel-filled thickness The plant becomes more susceptible to overwatering problems (slower growth = less water uptake) If your brightest windowsill isn't enough — common in north-facing apartments or basement spaces — a dedicated grow light makes a transformative difference. See our guide to the best grow lights for houseplants for setup advice. How to Water Aloe Vera: The Critical Skill If there's one skill to master for aloe vera care, it's watering. More aloe plants die from overwatering than any other cause. The thick, fleshy leaves store significant water reserves — the same gel you use on sunburns — which means the plant can go much longer between drinks than you might expect. The "Soak and Dry" Method The gold standard for watering aloe vera is soak-and-dry: water thoroughly until water drains freely from the bottom of the pot, then allow the soil to dry out completely — not just the top inch, but all the way through — before watering again. This mimics natural desert rainfall patterns (infrequent but substantial). Aloe Vera Watering Frequency Season Typical Frequency Notes Spring (active growth) Every 2–3 weeks Increase as temperatures rise Summer (peak growth) Every 2–3 weeks Check soil; heat dries soil faster Fall (slowing down) Every 3–4 weeks Reduce as temperatures drop Winter (near-dormant) Every 4–6 weeks Some growers skip December entirely These are guidelines, not rules. The actual timing depends on your pot size, soil type, temperature, humidity, and light level. Always check the soil before watering — if it's dry, proceed; if any moisture remains, wait. Signs of Overwatering vs. Underwatering Confused about what your aloe is telling you? Our guide on overwatered vs. underwatered plants goes deep on reading the signs, but here's a quick aloe-specific reference: Symptom Likely Cause Soft, mushy, translucent leaves Overwatering / root rot Leaves turning brown and mushy at the base Root rot (urgent) Yellow leaves overall Overwatering (most common) Thin, curling, or wrinkled leaves Underwatering (rare) Brown, dry leaf tips Underwatering OR low humidity Pale, washed-out color Too much direct sun OR overwatering The Best Soil for Aloe Vera Aloe vera demands fast-draining soil. Regular potting mix is too moisture-retentive and is one of the primary causes of overwatering problems even when watering frequency is correct. The solution is to either buy a dedicated cactus/succulent mix or amend standard potting soil heavily. Recommended Aloe Vera Soil Mix Cactus/succulent potting mix: Available at most garden centers, these pre-made blends include sand and perlite for drainage. A reliable starting point. DIY blend: 50% standard potting mix + 25% perlite + 25% coarse builder's sand. This drains extremely well and gives the roots the airy environment they thrive in. Pure perlite or pumice: Used by serious succulent growers, these near-inorganic media drain almost instantly and require more frequent (but small) waterings. Avoid soils with added moisture-retaining crystals or water-retention formulas — these are the opposite of what aloe vera needs. For a comprehensive look at soil types and amendments, see our best indoor plant soil guide. Pot Selection Terra cotta is the ideal pot material for aloe vera. Its porous walls allow moisture to evaporate through the sides, significantly reducing overwatering risk. If you prefer ceramic or plastic for aesthetic reasons, simply water less frequently. Pot size matters too: plant aloe vera in a pot only slightly larger than its root ball (1–2 inches wider). A pot that's too large holds excess soil that stays wet long after the plant has absorbed what it needs — a recipe for root rot. Temperature and Humidity for Aloe Vera Temperature Aloe vera is comfortable in the same temperatures most people keep their homes: 65–85°F (18–29°C). It can handle brief dips to 40°F (4°C), but sustained cold causes serious damage. Frost kills aloe vera immediately. Key precautions: Keep away from drafty windows and exterior doors in winter Don't place on cold stone floors in winter (cold wicks into the pot) If you move aloe outdoors in summer, bring it in before temperatures drop below 50°F at night Humidity Aloe vera is from an arid climate and handles low humidity well. Average indoor humidity of 30–50% is perfectly fine. Unlike tropical plants, aloe does not benefit from misting — in fact, moisture sitting in the leaf rosette can promote rot. Do not mist aloe vera. Fertilizing Aloe Vera Aloe vera is not a heavy feeder. In its native desert habitat, it grows in nutrient-poor soils — over-fertilizing is a common mistake that causes more harm than good. Excessive nitrogen pushes rapid, weak growth, and salt buildup from synthetic fertilizers can burn sensitive roots. Aloe Vera Fertilizing Guidelines Frequency: Once or twice per year is sufficient. Some growers fertilize in spring and early summer; others fertilize just once in spring. Type: A balanced, diluted liquid fertilizer (10-10-10 or similar) at half the recommended strength. Phosphorus-focused fertilizers (for blooming) can encourage flowering in mature plants. Organic options: A diluted worm casting tea or fish emulsion is gentler and harder to over-apply. When not to fertilize: Never fertilize in fall or winter, when repotting, or when the plant is stressed. For a full breakdown of fertilizer types and application methods, see our indoor plant fertilizer guide. How to Repot Aloe Vera Aloe vera needs repotting when its rosette has grown to fill the pot, when pups (baby plants) are crowding the pot, or when the roots are circling the bottom. Plan to repot every 2–3 years for young plants, and less frequently as the plant matures. Step-by-Step Aloe Vera Repotting Timing: Spring or early summer, during active growth. Water 24 hours before: Slightly moist soil holds together better during repotting. Choose your pot: One size up (1–2 inches larger diameter), with drainage holes. Terra cotta preferred. Remove from old pot: Tip the pot sideways and ease the root ball out. If roots are stuck, run a clean knife around the inside edge of the pot. Separate pups: This is the perfect time to detach any offsets that have formed. Baby aloes with roots of their own can be potted separately. Inspect roots: Trim any dead, shriveled, or rotted roots. The roots of healthy aloe are white to light brown and firm. Repot: Add a layer of fresh draining mix to the new pot, place the aloe, and fill around it. Bury the stem up to the base of the lowest leaves if it's become leggy. Wait to water: Allow 5–7 days before the first watering to let any root cuts callous over. For a detailed walkthrough that applies to all houseplants, see our step-by-step repotting guide. Aloe Vera Propagation: Growing New Plants from Pups Aloe vera is one of the easiest plants to propagate because it does most of the work for you. Mature aloe plants regularly produce offsets — small clones called "pups" or "babies" — that grow from the base of the mother plant. These can be separated and potted to create new independent plants. How to Separate Aloe Vera Pups Wait until the pup is at least 3–4 inches tall and has its own root system (you'll see this when you remove the parent from its pot). Use a clean, sharp knife to sever the connecting stem between parent and pup. Cut as close to the parent stem as possible without damaging parent roots. If the pup has roots, allow the cut end to callous for 24 hours in a dry spot before potting. If it has no roots yet, callous for 2–3 days. Plant in a small pot with well-draining succulent mix. Keep in bright light but hold off on watering for a week. Begin light watering once the pup stands upright on its own and shows new growth.

Harvesting Aloe Vera Gel One of the unique joys of owning aloe vera is having fresh, pure gel available any time for sunburns, minor cuts, dry skin, or hair care. Here's how to harvest it properly without harming the plant: How to Harvest a Leaf Choose a mature leaf from the outer rosette — these are the oldest leaves and have the most gel. Never take inner leaves; they're the plant's youngest, most active growth. Cut close to the base with a clean, sharp knife. Only take 1–2 leaves at a time to avoid stressing the plant. Stand the cut end upright in a cup for 10–15 minutes. A yellow-orange liquid called aloin will drain out — aloin is a laxative compound that can irritate skin and should be discarded. Slice the leaf open lengthwise and scoop out the clear gel with a spoon. Use fresh gel immediately or refrigerate in a sealed container for up to a week. For longer storage, blend with a small amount of vitamin C powder and freeze in ice cube trays. Note on skin sensitivity: While aloe vera gel is widely considered safe, a small percentage of people have sensitivities to raw aloe latex. If you're trying it for the first time, test on a small skin area first. Common Aloe Vera Problems and How to Fix Them Soft, Mushy Leaves (Overwatering / Root Rot) This is the most common aloe vera problem. If leaves feel soft, waterlogged, or translucent rather than firm, the plant has been overwatered. Check the roots immediately — if they're brown, mushy, and smell unpleasant, you're dealing with root rot. Act quickly: unpot the plant, remove all rotted roots with clean scissors, dust cuts with cinnamon (natural antifungal) or sulfur powder, and repot into completely dry, fresh draining mix. Do not water for 1–2 weeks. Our root rot treatment guide provides a complete step-by-step rescue protocol. Brown Leaf Tips Brown tips can indicate underwatering, low humidity, fluoride toxicity from tap water, or sunscorch. Check which conditions apply to your plant and adjust accordingly. Switching to filtered or rainwater often helps with tip browning caused by mineral sensitivity. Pale or Bleached Color A pale green or yellowish aloe is usually getting too much direct sun (bleached) or too little light (pale). Soft, bleached patches indicate sunscorch; overall paleness usually means insufficient light. Adjust placement accordingly. Leggy Growth (Etiolation) If your aloe's leaves are stretching sideways and the plant is losing its compact rosette form, it's reaching for more light. Move it to a brighter spot. Etiolated growth can't be reversed on existing leaves, but new growth will be more compact and upright once light conditions improve. Pests Aloe vera is relatively pest-resistant, but scale insects and mealybugs occasionally appear, usually hiding at the leaf bases. Wipe them off with a cotton swab dipped in rubbing alcohol, and follow up with a neem oil treatment. Our plant pest identification guide has photos and treatment protocols for every common houseplant pest. Not Producing Pups A young aloe vera (under 2–3 years old) rarely produces pups. As the plant matures and its root system fills the pot, pup production increases naturally. Ensuring adequate light and allowing the plant to become slightly pot-bound can also encourage pup production. Is Aloe Vera Safe for Pets? Aloe vera is toxic to cats and dogs. The saponins and anthraquinones in the plant (particularly concentrated in the yellow latex layer beneath the green skin) can cause vomiting, diarrhea, lethargy, and changes in urine color if ingested. The clear inner gel is much less toxic but is still not recommended for pets to consume. Keep aloe vera out of reach of curious pets — on high shelves, in rooms pets don't access, or in hanging planters. If you have cats or dogs that regularly investigate your plants, our curated pet-friendly houseplant collection features beautiful plants that are completely safe for your animals. Best Aloe Vera Varieties for Indoors While Aloe barbadensis miller (the classic aloe vera) is by far the most common and useful species, the Aloe genus contains hundreds of fascinating species worth exploring. Variety Key Feature Best For Aloe vera (A. barbadensis) Classic gel plant, pale green with white spots Medicinal use, windowsills Aloe aristata (Lace aloe) Compact, white-spotted, more cold tolerant Small spaces, beginners Aloe humilis (Spider aloe) Small rosette, blue-green with spiny teeth Terrariums, small pots Aloe variegata (Tiger aloe) Striped green and white, compact Decorative display Aloe polyphylla (Spiral aloe) Stunning spiral rosette Collectors, statement pieces Aloe Vera Outdoors: Moving Your Plant Outside in Summer Aloe vera thrives outdoors in summer in most climates — the extra light, airflow, and heat produce noticeably faster growth and deeper color. Here's how to transition safely: Acclimatize gradually: Start in a shaded or dappled-light spot for 1–2 weeks before moving to a full-sun position. Jumping straight from indoor to full outdoor sun causes sunscorch. Monitor watering: Outdoor plants in heat dry out faster. Check soil every 7–10 days in summer heat. Bring in before frost: Aloe vera cannot survive frost. Watch nighttime temperatures — bring indoors when lows drop below 50°F (10°C). Where to Place Aloe Vera in Your Home The kitchen windowsill is the classic aloe vera spot — and for good reason. Having fresh gel immediately accessible for minor burns and cooking mishaps is genuinely useful. But aloe vera's sculptural form also makes it a beautiful accent throughout the home: South-facing windowsills (the brightest indoor spot) for maximum growth and gel production Kitchen counters near a bright window for practical accessibility Sunny bathroom windowsills — the light and warmth suit aloe perfectly Outdoor patios in a terracotta pot during the warm months Looking for more easy-care plants for bright spots in your home?

Frequently Asked Questions About Aloe Vera Care How often should I water my aloe vera? Every 2–3 weeks in spring and summer, every 4–6 weeks in fall and winter. Always check that the soil is completely dry before watering. The exact timing depends on your pot, soil, and environment. Why are my aloe vera leaves turning brown? Brown tips usually mean underwatering or tap water sensitivity. Brown, soft leaves mean overwatering. Brown and bleached patches with a dry texture mean too much direct sun. Identify which type of brown you're seeing and address accordingly. Can aloe vera grow in full shade? No. Aloe vera needs several hours of bright light daily to stay healthy. In full shade, it will slowly decline. If natural light isn't available, use a grow light. When does aloe vera flower? Mature aloe plants (usually 4+ years old) can produce tall flower spikes with tubular orange, red, or yellow blooms in late winter or early spring. Flowering is triggered by adequate light and a cooler, slightly drier winter rest period. Aloe vera flower spikes are a sign of a very healthy, mature plant. Can I use aloe vera gel from the store on my plant? You're thinking of it the other way — your plant produces the gel, not the other way around. Aloe vera gel products from the store contain preservatives and additives that aren't useful for plant care. Final Thoughts: Mastering Aloe Vera Care Aloe vera asks for one thing above all: let it dry out between waterings. Master that single principle, give it enough light, and plant it in fast-draining soil — and you'll have a thriving, gel-producing specimen that rewards you for years with both beauty and utility.

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.
