Begin with the habitat
Check whether your plant comes from an arid or tropical environment. This affects its light, moisture and compost requirements.

COIROLOGY GROWING GUIDES
Cacti & succulents
A free-draining root zone is essential for many desert cacti and succulents. Choose a mix that suits the species and dries appropriately in your growing conditions.

A PRACTICAL GUIDE
Prepare. Plant. Care.
Build the right structure
Choose a specialist peat-free cactus mix or a species-specific blend. Coir chips may suit some rainforest cacti, but their retained moisture means they are not a universal drainage solution for desert species. Many desert cacti need a more mineral-rich mix; select components around the plant and drying conditions.
Use a draining container
Choose a pot with drainage holes and a size appropriate to the roots. Avoid water collecting inside an outer pot. Handle spiny plants with suitable protection.
Match watering to growth
Allow the medium to dry as appropriate for the species before watering again. Reduce watering when growth slows and conditions are cool. Feed according to the plant’s requirements and fertiliser label.
