Terrariums are magical miniature pieces of nature that you can admire anywhere in your home. They are living pieces of art. You don’t even need to be a master gardener (I certainly am not) to put together and care for your own terrarium or dish garden, but you do need to know a few things about what kinds of plants need how much light and watering. Designing your own terrarium allows to you get creative and let your imagination run wild. You can include miniature statues of mythical creatures, little signs and pretty rocks. If you can’t find what you want, you can even make little mushrooms or animals out of oven bake clay.

Terrariums are enclosed, so the plants need to be small enough to grow inside of a glass jar, a small glass box or any clear container. Wide-mouthed glass containers with a removable lid are the easiest to work with because you have easy access to water and prune as you need to. You can even mount your terrarium on the wall in a light box or hang it from the ceiling in a glass globe. It all depends on your imagination and the things you can find. People have even made tiny terrariums inside old light bulbs!

You Need

A container
A group of small plant starters that will grow under the same amount
of light and watering.
Some sand or small pebbles
Activated charcoal
Spaghnum moss
Potting soil

You should plan out how you want it to look before you start collecting your supplies–make a sketch or just have a vivid image in your head. The first thing you will place in your container is a layer of coarse sand or small pebbles that is about one inch thick. This layer is for drainage and will keep your plants’ roots from rotting.

Next you will need to lay on a thin layer of activated charcoal–the same kind they use in aquarium filters to keep the air flow or water flow clean, so you can find this at the pet store. If you are planting in an open-air container you won’t need this.

Lay down your Spaghnum moss in a thin layer so that your soil won’t sink down into the charcoal and pebbles every time you water it.

Now you can add your soil. You can buy pre-mixed terrarium soil blends or you can just mix 2 parts regular potting soil, 1 part coarse builders sand (never use beach sand) and 1 part leaf mold (aka humus). You don’t need to add fertilizer because you don’t want the plants to grow very large and there is already a substantial amount in the potting soil.

Sometimes all your little plants require for watering is a good misting from a spray bottle to emulate rain. You should never place your terrarium in direct sunlight.

If you want to make a desert-themed cactus garden, this would be much easier to do in a dish rather than a terrarium. Since cacti and succulents need drier, sandy soil, you can use special potting soil
made for them or put your potting soil down and then place an equal layer of coarse sand on top after you plant your cacti. You don’t need spaghnum moss, charcoal or pebbles for a desert garden, but if you are using a planter dish with a hole at the bottom, be sure to put a small piece of screen over it so your sand doesn’t fall out. Also, unlike a terrarium, your cacti will need plenty of direct sunlight. Wear thick gardening gloves if you are working with sharp cacti!

Your cacti will only need to be watered about once a month. Always make sure you water your plants with luke warm water instead of cold water so you don’t shock the roots. Image someone throwing ice cold water on you on a hot day!

I hope I’ve sparked your interest for making your own terrarium! They make great little decorations and interesting gifts. Here is a list of a few small plants that would be good for a terrarium or dish garden but this definitely isn’t all of them. Do some research on the care of the plants that you want to use and let your imagination run wild as you plan out the look of your mini garden.

Irish Moss

Great for any tiny landscape and only grows to a max of three inches tall.

Miniature Peperomia

Stays small and and has tiny round leaves. Very easy to maintain.

Wintergreen

Grows to about six inches tall and is very hearty. Blooms tiny white flowers in the summer and smells minty.

Dwarf Japanese Sweet Flag

Tiny ornamental grass that resembles an Iris plant, but only grows to two inches tall.

Leptinellas

Looks exactly like an itty bitty fern and are often refered to as “mini ferns”. These are also easy to take care of.

Butterwort

Cool little carnivorous plant that attracts insects like a living fly paper and dissolves them with digestive juices on its leaves. Only grows to about one inch tall with sticky leaves but will bloom a pretty purple flower.

Mini Bonsai

Would be a cool addition to a dish garden but would be hard to maintain in a closed container because they need to be trimmed and trained into the bonsai shape.

Earth star AKA Starfish Plant

It stays under six inches tall and grows a rosetted star shape of long, spiked leaves. It is easy to care for and is perfectly suited for a terrarium because it loves humity.

Succulents

Cacti and other succulents like Aloe Vera and Jade grow very slowly and will eventually outgrow whatever container you put them in. Plant them when they are small and you’ll be able to enjoy your mini desert garden for quite a while.
