In short: Coco coir is generally NOT ideal for succulents — it holds too much moisture even when freely-drained, raising root-rot risk. It can work as a small component (10–20%) in a primarily inorganic succulent mix (perlite, pumice, coarse sand). For most succulents, a dedicated cactus/succulent mix is a better starting point.
Succulents have surged in popularity across UK homes, prized for their low maintenance and striking appearance. But can you grow them in coco coir? The short answer is yes—with the right approach. Here’s everything you need to know about using coco coir for succulents.
The Challenge: Water Retention vs Drainage
Succulents evolved in arid environments and store water in their leaves and stems. They need fast-draining growing media that dries quickly between waterings. Coco Coir, by contrast, is valued for its excellent water retention—which seems contradictory.
However, this is easily solved with the right amendments. Pure coco coir isn’t ideal for succulents, but a properly mixed coco coir blend is excellent.
The Perfect Coco Coir Mix for Succulents
Standard Succulent Mix
Mix 1 part Blue Apple Garden coco coir with 1 part perlite and 1 part coarse horticultural sand. This creates rapid drainage whilst retaining just enough moisture for healthy roots.
For Very Drought-Tolerant Species
Use 1 part coco coir, 2 parts perlite, 1 part sand. This dries even faster for cacti and lithops.
For Semi-Succulents
Plants like aloe vera and jade plants tolerate slightly more moisture: 2 parts coco coir, 1 part perlite, 1 part sand.

Benefits of Coco Coir for Succulents
- pH stability: Our buffered coco coir (pH 5.5–6.5) suits most succulents perfectly
- Lightweight: Ideal for hanging planters and shelf displays
- clean and safe: Reduces risk of fungal diseases common in succulents
- Sustainable: Unlike peat moss, coco coir is renewable and eco-friendly
- Easy rehydration: Dry coco coir reabsorbs water readily—important for the soak-and-dry watering method succulents prefer
Which Succulents Work Best?
Excellent in Coco Coir Mixes
Echeveria, Sempervivum (houseleeks), Aloe vera, Haworthia, Jade plant (Crassula ovata), Sedum, String of pearls.
Require Extra Drainage
Cacti, Lithops (living stones), Conophytum—use the higher perlite/sand ratio for these.
UK Winter Care Tips
UK winters pose specific challenges for succulents:
- Move to brightest windowsill available (south-facing ideal)
- Reduce watering to once every 3–4 weeks
- Ensure the coco coir mix dries completely between waterings
- Keep away from cold draughts and single-glazed windows
- Avoid repotting during winter dormancy
