How to plant up a terrarium

Pour gravel into a clean vessel up to 3cm high, then level it with your hands. Pour or scoop in slightly moist compost to a depth of 4cm above the gravel and use your hands to level and firm it. Use your fingers, a stick or the back of a paintbrush, create small wells in the compost for your plants. Gently squeeze the plants out of their pots and place them into the wells and gently firm the compost around them. If the plants have spines you may need to use tweezers for this step. Look at your terrarium from all angles, adding more plants if you think it needs them. Finally, spoon a mulch such as white sand or gravel over the compost. Use the tweezers to pick up and place any decorative pebbles. Water each plant by carefully dripping a dessertspoon of water around their base.

Leafy bottle terrarium

This vintage bottle is filled with shade-tolerant house plants. Put this lush display in a bright spot, out of direct sunlight. A layer of moss helps retain moisture.

We used

• Vintage glass bottle
• Grit
• House plant compost
• Leafy house plants such as peace lily (back), caladium (left), fittonia (front)
• Moss (from a lawn)

Succulent geometric terrarium

This angular display is ideal for a warm, bright windowsill. Succulent plants, such as echeverias, will thrive in the dry, open setting, and will need watering very rarely. A fine grit mulch adds a neat finishing touch.

We used

• Copper-framed angular terrarium
• Cactus compost
• Succulent plants such as Echeveria agavoides 'Vashon' (front right), Crassula mucosa (back left), haworthia (centre)

Simple terrarium with air plant

The key to this display lies in its simplicity. The glass vase is filled with a layer of black gravel and the air plant (Tillandsia) has been nestled into it. Great for a slightly humid spot.

We used

• Asymmetrical glass vase
• Black gravel
• Tillandsia (air plant)

Hanging terrarium

Hanging house plant displays are an effective use of space – group the terrariums together and fill with different plants. Hang them from a shelf or hook in a warm spot out of direct sunlight.

We used

• Hanging spheres
• Bromeliads, succulents or cacti
• Rustic string
• Gravel

Sphere terrarium

A sphere terrarium makes a good home for an air plant, as the slightly curved sides keep in the humidity that the plant needs. A couple of cork slices and a piece of garden twine create a flotsam-and-jetsam on-the-beach feel.

We used

• Sphere terrarium
• Pale gravel
• Tillandsia (air plant)
• Cork slices
• Garden twine

Cactus and aloe cube terrarium

An open cube terrarium like this makes a stylish home for desert plants, such as cactus and aloes, which will be happiest in a dry location. A mulch of pale grit and chunky pebbles add interest and help to produce a landscape in miniature.

We used

• Cube terrarium
• Cactus compost
• 3 x small cactus plants, aloes or Haworthia
• Pale grit
• Chunky pebbles

Leafy coloured bottle terrarium

This globe jar makes an attractive table centrepiece. The soft texture of the moss contrasts with the smooth stones and sets off the plants.

We used

• 3 x plants with patterned leaves such as fittonia and Calathea picturata
• Cushion moss
• House plant compost
• Gravel and pebbles
• Round glass jar

• Cushion moss
• House plant compost
• Gravel and pebbles
• Glass jar with cork lid

Shade-loving sealed terrarium

• Cacti and succulent compost
• Gravel, sand and pebbles

• Pink and white fittonias
• Cushion moss
• House plant compost
• Activated charcoal
• Gravel and small pebbles
• A sealable glass vessel with a glass or cork lid
