Insect Eating Plants

biofreakbiofreak Posts: 1,084

I have just bought 2 insect eating plants to munch up the flies in the kitchen. They are thriving, and no flies around at last. But - one is too big for its pot. What sort of soil do I use to transplant it. I thought aquatic soil because the plants rest in water all the time, but not sure. All advice welcome.

    I think they require peat based or just peat compost and rain water

    Books don't seem to mention what they need, and Garden Centres useless so thanks for advice. I am using pond water which they love. Will now pot on. They say you need three different varieties in kitchen to be effective - I bought 2 to start with any ideas for a third? I have one big bottle shaped one (the one to re-pot) and 1 classic venus fly trap. I've seen some sticky ferny one's - any good

    50% peat (make sure it hasn't been fertilized) plus 25% horticultural grit and 25% perlite works well for me. I grow both tropical and total hardy carnivorous plants

    rain water is best, especially if you live in a hard water area as they prefer acidic conditions.


    what variety/species have you got? as all have slightly different needs.

    The stick ferny ones are Sundew

    Hi treehugger - According to the labels I have one Sarracenia which has swallowed 2 houseflies today and one Dionaea which seems to prefer mini flies and midges! Boots the Bengal sniffed the latter this morning and was shocked to feel it close up around his whiskers - not a happy cat!!

    luckily both those are fine on the mix I told you previously, usually you pot up in the dormant season (winter) but as long as you don't disturb the roots too much they should appreciate a bigger pot.

    plus at this time of year you can put them outside in a sunny patch and they should like the fresh air and rain (if we get some)

    one thing with the fly trap (Dionea) don't trigger the traps without something in it (as tempting as it is!) as the traps only shut three to four times then die back.

    Hi treehugger. Thank you so much for letting me know this - I did wonder when and if they gave up! Will tell Boots the Cat to stop interfering! What would you recommend as a third choice to add to the range?

  • treehugger80treehugger80 Posts: 1,923

    I would recommend a sundew, Drosera binata or fork leaved sundew is a good (and easy to grow) one.

    I have the Drosea binata multifida extrema variety, its nearly four feet across at the moment and its only four years since I took it as a leaf cutting from my brothers plant!

    its hardy down to about -5 c and I keep mine in a conservatory over winter and then it hangs over my patio from june till September happy eating all the bluebottles and wasps it can get its leaves on.

    Oh my giddy aunt - Sounds like a Triffid - Aren't you worried that it might try to eat you?!!


    Thanks for info - so glad to find someone who knows about these. Garden Centres seem to look on them as just a novelty and tell me to read the labels.

    it does give me a giggle when my friends walk into it by accident and scream like five year old school girls (and that's just the six foot tall male rugby players I know!)

    garden centres and even nurseries and pretty useless when it comes to carnivorous plants, usually they're right next to the cacti's in the houseplants section and usually bone dry!

    best bet is contact the specialist nurseries like South West carnivorous plants, Hampshire carnivorous plants or Hewitt-Cooper carnivorous plants they'll always be happy to give advice to a new grower
