Top Terrarium Tips

Simple DIY projects make for a unique date night or fun activity with family and friends. These little glass desert gardens are the perfect combination of stylish decor and low-effort plant parenting. They’re straightforward to assemble and require few materials. All you have to do is set them up in a bright space with indirect light, be mindful of watering schedules, and keep them somewhere that doesn’t supply heat.

We asked Ashley, one of our team members, to share some of her top terrarium tips. Let’s dive in and explore a few ways to keep your arrangement looking beautiful and healthy.

Location, location, location.
The ideal space for a terrarium is one that provides indirect sunlight and isn’t near a heat source. Glass intensifies the strength of the sun’s rays which could result in foliage sunburn and increased heat levels. Radiators, heaters, and tops of fridges are also constant heat sources that will dry out your plants and potentially damage their leaves. Ashley often chooses desktop or shelf locations with indirect sunlight as safe options.  Study your arrangement’s location to determine if your terrarium is in a suitable space. 

Next, be aware of whether you have an open or closed terrarium.
Ashley prefers open terrariums and uses containers that provide air circulation. She suggests looking for glassware with an open-top or side.  This type of environment is ideal for low-maintenance plants: slow-growing varieties that will thrive with minimal hydration and care. Her favourites are sansevieria, cacti, succulents, and air plants.
Closed terrariums require glassware with some form of a lid, which creates a more humid environment. There are so many tropical foliage plants that will thrive in a more moist habitat. Some of Ashley’s favourites include calathea, polka dot plants, baby tears and nerve plants. These varieties will grow faster than those in an open terrarium so feel free to rearrange or trim them back if certain plants are hogging all of the light and space inside the glass. 

Finally, be careful of overwatering which is easy to do with small containers. Ashley’s tip is to use a measuring spoon or spray bottle when irrigating your arrangement. These tools can assist with creating moist, rather than soggy soil.

The best arrangements are those with personality. Add a few shells or seaside glass from your last beach walk, pebbles from your garden, or a small rubber dinosaur from your kid’s toy collection. 

Happy planting!
