Terrariums are a wonderful addition to any plant collection, bringing variety, depth, and beauty to your indoor space. Making an upcycled jar terrarium is not only a creative project but also a sustainable way to repurpose materials you already have at home. This DIY activity is also a great way to engage your kids in a fun and educational gardening project.
About Terrariums
Terrariums are miniature, enclosed gardens that create a unique microclimate for plants to thrive in. These self-contained ecosystems provide a moist environment that allows you to grow plants that may not typically do well in your home environment. With minimal care and upkeep, terrariums can add a touch of greenery to your space while requiring less maintenance than traditional potted plants.
Typically, terrariums are housed in clear containers with lids to create a greenhouse effect. While some variations may not have lids or use tinted glass, it is recommended for beginners to start with a clear container to observe the growth of their plants effectively. It’s important to place terrariums in a location with indirect sunlight and moderate temperatures to prevent overheating.
Materials Needed
- Used jar (2 quarts or larger): Opt for a spacious jar like a pickle or pretzel jar for your terrarium.
- Soil: Mix in a bit of compost with your potting soil for added nutrients.
- Rocks: Use small rocks or pebbles at the bottom of the jar to aid in water drainage.
- Used pantyhose (or moss, or other thin fabric): Create a barrier between the rocks and soil to prevent clogging. Cut and layer pantyhose, moss, or fabric to cover the rocks completely.
- Plant: Choose a plant that thrives in a moist environment and fits well in your jar. Recommended plants for terrariums include polka dot plants, prayer plants, ferns, and more.
- Scissors
- Trowel
- Newspaper (optional): Use newspaper for easy cleanup when working indoors.
- Glass cleaner and rag
Setting Up Your Upcycled Jar Terrarium
Step 1: Prepare the jar
Thoroughly clean the jar, removing any residue and labels. Create holes in the lid for ventilation using a drill or a nail. Ensure the holes allow for proper airflow within the terrarium.
Step 2: Layer in the rocks, barrier, and soil
Start by adding a layer of small rocks at the bottom of the jar, followed by a barrier of pantyhose or fabric. Then, add the potting soil and compost mixture for planting.
Step 3: Add the plant
Dig a hole in the soil and carefully plant your chosen plant in the jar. Trim any excess leaves or roots for a neat fit. Use a narrow trowel or spoon for planting in the confined space.
Step 4: Tidy up and water the plant
Clean the jar’s exterior and water the plant as needed. Place the lid on the jar to create a sealed environment for your terrarium.
Enjoy Your Upcycled Jar Terrarium
Monitor your terrarium for any signs of mold or wilting, and make adjustments as needed. With proper care, your upcycled jar terrarium will thrive and bring a touch of nature into your home. This sustainable gardening project is not only a creative endeavor but also a way to promote environmental consciousness through upcycling.
