Care, Cost and Maintenance
Watering Wisely
Use a spray bottle to mist the soil and plants. Closed terrariums need very little water; open ones need slightly more. Check soil moisture before watering.
Lighting Requirements
Place in bright, indirect light. Direct sun can overheat the terrarium. If using artificial light, keep it on for 10-12 hours a day.
Pruning and Cleaning
Trim dead leaves and wipe glass to prevent mold. Remove any decaying matter promptly to maintain a healthy ecosystem.
Pro tip
When assembling your terrarium, use a spray bottle to moisten each layer before adding the next-this prevents dry pockets and helps roots establish quickly.
Frequently asked questions
How often should I water my terrarium?
Check the soil moisture every week. Closed terrariums may need water only every 2-4 weeks; open ones every 1-2 weeks. If condensation appears on the glass, skip watering.
Can I use tap water for my terrarium?
It's best to use distilled or filtered water to avoid mineral buildup and chlorine damage to sensitive mosses and plants.
Why is my terrarium moldy?
Mold often results from too much moisture or poor air circulation. Reduce watering, remove affected material, and increase ventilation by opening the lid periodically.
What plants are best for a closed terrarium?
Choose moisture-loving plants like ferns, mosses, and small tropical species such as Fittonia or Pilea. Avoid succulents and cacti, which need dry conditions.
How long will a terrarium last?
With proper care, a closed terrarium can last several years. Open terrariums may last 6-12 months, depending on plant selection and maintenance.
