|Which compost do you need for venus flytraps?|
Out of all the carnivorous plants that you can buy, the Venus Flytrap is perhaps one of the easiest to grow. The one thing to remember is that it does come from a specialist environment which is why it obtains its ‘nutrients’ in such a unique way. This does mean however, that Venus flytraps require a rather specialist compost mix to grow in otherwise these plants will almost certainly die.
WARNING, you cannot plant Venus flytraps into a multi-purpose compost!

Peat moss makes an ideal starting point for making carnivorous plant compost because it is both nutrient poor and slightly acidic. At no point should you need to add any fertiliser or lime to the compost mix as this will cause root damage through ex-osmosis.
The definition of osmosis is:
'...osmosis is the diffusion of water through a semipermeable membrane. More specifically, it is the movement of water across a semipermeable membrane from an area of high water potential (low solute concentration) to an area of low water potential (high solute concentration)...'
Ex-osmosis occurs when the concentration of soluble nutrients in the roots environment is greater than the concentration of soluble nutrients within the actual root. When this happens water moves from the root cells to the soil causing a state of dehydration within the root. If ex-osmosis continues then the root cells eventually die causing a condition known commonly as 'root burn'.
It is also worth transplanting your Venus flytraps into fresh compost every few years as this will help to avoid an inevitable build up of nutrients and toxins within the root environment.
