This Terrarium Plant Arrangement in a Glass Dome with Cork Lid is a compact, self-contained miniature garden featuring carefully chosen small plants—such as mosses, succulents, or air plants—arranged on a layered substrate inside a clear glass globe. The cork lid creates a semi-closed environment that helps retain humidity and reduces watering frequency, while the transparent dome showcases the plants from every angle. Ideal for desks, shelves, and small spaces, this low-maintenance decorative piece brings a touch of greenery and calm with minimal care: bright, indirect light, occasional misting or light watering depending on plant type, and good airflow when the cork is briefly removed.

Light

• Bright, indirect light is best. Place near a north- or east-facing window or a few feet back from a south- or west-facing window.

• Avoid direct midday sun; glass can magnify heat and scorch plants.

Temperature & Humidity

• Keep between 60–75°F (15–24°C). Avoid cold drafts and heat sources (radiators, vents).

• The closed cork lid keeps humidity high—ideal for tropical, moisture-loving plants. Remove the lid occasionally (see Ventilation) if condensation is constant.

Watering

• Water sparingly. Closed terrariums recycle moisture; overwatering causes rot and mold.

• Check soil moisture with your finger or a wooden skewer: water only when the top 1 inch (2–3 cm) of soil is dry.

• Use a small watering can or syringe to add water directly to the soil, avoiding splash on leaves. Typical frequency: every 4–8 weeks, depending on light and season.

Ventilation

• Open the cork lid for 10–30 minutes once a week to exchange air and prevent mold.

• If heavy condensation builds up on the glass, leave the lid off longer or open daily until humidity stabilizes.

• For permanently high humidity plants (mosses, ferns), reduce airing to avoid drying them out.

Soil & Drainage

• Use a well-draining terrarium mix: a base layer of small pebbles or activated charcoal for drainage and odor control, then a light potting mix suited to your plants.

• Do not add a thick drainage layer of soil—keep substrate shallow to fit the dome and maintain proper moisture balance.

Pruning & Maintenance

• Trim back any overgrown or dead foliage to prevent decay and maintain airflow.

• Remove moldy debris immediately.

• Clean the inside of the glass gently with a soft cloth if algae or film appears (remove plants temporarily if needed).

Pests & Problems

• Watch for fungus gnats, mealybugs, scale, and mold. Isolate the terrarium if pests appear.

• Treat pests with manual removal, diluted insecticidal soap, or a targeted biological control suitable for enclosed environments.

• If plants show yellowing, mushy stems, or foul smell → likely overwatered. Remove affected plants, dry soil, and increase ventilation.

Plant Selection

• Best for small, slow-growing, humidity-loving plants: baby ferns, fittonia, peperomia prostrata, small begonias, mosses, and air plants (with different watering).

• Avoid large, fast-growing, or drought-loving plants (e.g., succulents) in a closed cork-lidded dome.

Placement & Safety

• Place on a stable, level surface away from direct heat and cold.

• Keep out of reach of pets and small children (glass and small parts can be hazardous).

Seasonal Notes

• Growth slows in winter; reduce watering and increase ventilation frequency to avoid condensation from temperature swings.

• In summer, check more often for moisture buildup and heat stress.
