Terrarium Potting Mixes


Whether you're making a Tropical or Desert-themed terrarium, we've got you covered with our quality compost & FREE delivery! 'Tropical' Terrariums are those that use leafy houseplants like Ivy, miniature Palms, Peace Lilies, whereas 'Desert' terrariums are for Cacti & Succulent displays. (The two are differentiated by the soil). Select your soil-type & size and we'll get to work!

Our handcrafted compost comes in a resealable bag, meaning that you can always use it later if you have too much. It'll also stay fresh for at least twelve months once opened, so never worry about it going off shortly after purchase. We formulate the soil ourselves and keep it in quarantine for 14 days to ensure there are no soil-borne pests like Fungus Gnats.

Which Soil Do I Need?

Our Terrarium Compost has two variants, both 'Tropical' or 'Desert' themed, that are different in drainage and water-retention ability.

'Tropical Terrarium' Soil
If you're looking to create a leafy, exotic-looking terrarium, we recommend using 'Tropical' soil. This will provide the perfect blend of water retention and drainage to promote healthy growth, topped off with 'perlite' that'll add oxygen back into the compost for stronger root development. 

'Desert Terrarium' Soil
This compost is best suited for those who want to make a desert-themed display with Cacti & Succulents. Our soil comes packed with goodness that promotes drainages and will help reduce the risk of over-watering, like grit, sand and perlite.

Background Information

For the last five years, we have been formulating composts for our houseplants, balancing the critical ingredients for different groups (Bonsai, Bulbs, Cacti, Tropicals, etc.), with varying ratios of compost, perlite, grit & sand. We believe that a well-structured soil is critical for maximising both the root and foliar growth performance. We source the compost from well-respected companies in the U.K., which has tight restrictions over quality control & environmental regulations/promises.

Checklist for a Successful Terrarium:

  • Combine the Right Plants: Never rush into buying every small plant that you see at a store. Always decide on whether you're going to create a Desert or Tropical themed display. Combining a desert-dweller with a moisture-loving specimen will serve nothing but grief for both parties, as one will either be under or over-watered. 
  • Successful terrariums require good drainage, so make sure you have a basal layer of stones, a thin layer of 'Activated Charcoal' and the correct potting mix. (Desert-themed displays need 'Cactus' labelled soil, whereas tropical displays need 'Houseplant' compost).
  • Need to purchase the stones and activated charcoal, too? Why not buy our 'Terrarium Kit', which will include everything you need to provide the best drainage for your terrarium! (Charcoal, compost, and coloured stones).
  • Maintain bright light. We recommend keeping your Tropical terrarium in a bright windowsill without any direct sun (north or east-facing windows are best). In contrast, Desert-themed displays should at least be exposed to morning or evening sunlight, like a south or west-facing window.

You can always book a 1-1 Video Call with Joe Bagley if you have any queries or questions!

Through experience and research, we have developed a fine-tuned sense of how well-structured compost should look and feel. Along with using quality ingredients, we source the compost from a widely-known company to the Horticultural Industry, based in Southern England. We have studied hundreds of species' basal structures to ensure the formulated compost is complimentary to the individual plant, whether it has a rhizomatous, tuberous, cormous or the traditional root system.
All of our composts come in a resealable bag, so never worry about having a little extra left over. Simply enclose the lid and situate it in a dry, dark area away from pets and children. The soil's freshness will last at least twelve months once opened, so it's great for emergency repotting and top-ups.
Unfortunately, our handcrafted composts are only available to those in the U.K., due to E.U. trading laws on plant-based materials. However, if you are in the U.K., expect free delivery and postage within three days of purchase! 
Any good compost will only hold a certain volume of water before dripping the excess through the drainage holes. With this in mind, you're most likely going to cause root rot by watering the plant too often instead of the exact amount of water per drink.

Here's an example. It's far better to water the plant 7L in one go once a week, as supposed to 1L per day for the entire week. The roots won't be able to access the oxygen within the soil, which is critical for reducing the development of root rot. Like bubbles in an ocean, the air will rise when the potting mix is wet, so it's essential to allow the soil to dry slightly between drinks to regain the oxygen.

Our Repotting Kits are designed to maximise both the air circulation and soil structure around your plant's roots, meaning that it'll have the very best conditions for optimal growth. Remember not to water the soil too frequently, and your little friend will very much enjoy his new home!

We'll send you a confirmation email with the purchase's receipt, along with a Step-by-Step Guide on repotting your plant. You can then refer to the guide once your compost arrives! 😊
