It's Time to Get Your Hands Dirty: The Basics for Making a Terrarium

When I worked at Cudmores Garden Centre, I was often involved in collecting the materials for and putting together the pre-made planters that were sold. During this time I received a lot of tips about how to plant the individual items (yes, there is a proper way); as well as how to organize a collection of plants to make them look the best. I was interested to discover that succulents/cacti and annuals follow a lot of the same basic rules. The biggest difference is that terrariums usually include many decorative objects as well.

            In my opinion the most important note to remember when you start the hands on aspect of any gardening is probably the most commonly forgotten one; remember plants are living things too! They require a gentle touch and lots of love just like anything else we take care of. I found it interesting that not many resources I explored about the DIY steps talked about the importance of a gentle touch. At my old job was one the most common tips!

Okay, that’s enough with the background information. After a bit of searching, I decided these basic guidelines were the most important to remember when creating your own terrarium.

The first thing to do is to collect all materials. I will be using an open top container that is suitable for plants requiring a dry environment; a collection of 3 or 4 (depending on the size) individual plants in the succulent and cacti families; some decorative rocks of varied natural colours; a bit of artificial moss and possibly a few shells.

Once I have my materials laid out in front of me I will start by placing about an inch of rocks at the bottom of the container with a small well (hole) in the middle and then cover that with fiberglass window screen. This bottom layer is needed because my container will not have a drainage hole, so I need to create a space for excess water to sit in order to allow the soil to dry out, as the plants require. The well I created is to help make space for root growth and the fiberglass window screening is there to stop the soil from falling down into the rocks

Next I will top the fiberglass screening with a few inches of moist soil. The amount I put in will depend on the desired look I am after, I will probably decide exactly how much I want to put in once I have the materials in front of me. The important part is there needs to be enough soil for proper depth and root growth. The good thing about succulents and cacti is they don’t need to be planted very deeply. It is also important to lightly moisten the soil before placing it in the terrarium so the plants are in a healthy environment as soon as they are planted.

Based on the containers I have been looking at most recently I will probably choose one that can be looked at from all angles so I will likely need to plant the tallest plants towards the middle and the smaller ones around the outside. When I get to the individual succulents I will first rearrange them on the table within their containers so I know the desired look I am after. Once I have decided on the placement of each plant I will take them out and place them in the terrarium one by one. Before planting it is helpful to remove as much of the excess soil and white perlite (little white specs) until you are mostly dealing with the roots.

After the plants are comfortably under the soil I will be able to start placing my decorative materials. For me it’ll be about simplicity and a clean look. I’ll also want to make sure the plants aren’t too crowded and have enough airflow.

Take a look at the videos below to see some other peoples preferred styles for making a Terrarium. The steps are slightly different than mine, but as long as they have the basics it’s all about personal preference!  



Next on my list of things to learn is how to properly care for a terrarium and whether my bedroom will be an accommodating environment for one… fingers crossed!
