Soil for a Venus flytrap
Use an acidic, low-nutrient carnivorous-plant medium. Ordinary potting compost or garden soil is too rich for Dionaea muscipula.
Check how the mix holds water and air
Best soil mix
Use an acidic, low-nutrient specialist carnivorous medium. The exact RHS profile names acidic potting medium mixed with moss, while its carnivorous guide lists peat-free options built from moss, bark, sand, or perlite. No single ratio is established.
The medium should stay evenly damp while remaining well drained. RHS describes damp container cultivation through a water or saucer approach and warns against stagnant or inappropriate media. The guidance does not prescribe one pot or saucer configuration.
Separate indoor and outdoor advice
Match the mix to the pot and setting
This soil decision belongs to a low-nutrient carnivorous-plant container, commonly under glass or indoors in bright light. Ordinary garden soil and standard potting compost are too rich for this use.
Use an exact target only when one is known
Soil pH
Dionaea muscipula requires an acidic medium. The exact profile does not give a numeric pH target, so do not adjust it with household products by guesswork.
Check the pot, watering and roots too
When soil alone is not the problem
