Carnivorous Plants/Soil requirements for mixed pots


Hi Jeff,

as mentioned previously, IŽll repot my plants within the next two weeks, I think the right time has come.

However, as far as I know flytraps for example like a soil that is a bit more sandy than pitcher plants, right? So the question I ask myself, whether I can have these plants together in a same container with the same soil mix. (40% peat, 40% sand, 20% perlite maybe) Or maybe it would be beneficial to have the flytraps in this container placed in a spot with a bit more sand below?

The same thing I thought about Sarracenia psittacina, that likes to be flooded once in a while. Would this one make sense to be potted alone?

I donŽt know whether or not I am exaggerating, I just want to make sure to have the best setting for each plant while having some species together in a bigger planter.

One last thing, about perlite, do you guys use it? I read that no more than 20% are recommended...

By the way, IŽll be going to Belgium over the weekend, my country of origin, please let me know which chocolates tastes you like the most, I am not kidding!

Variations can be found here! (only French/Dutch website)



Hi JP,

This issue with North American temperate species starts to be splitting hairs some.  We pot all of our hardy plants in the same mix, 40% peat and 60% perlite.  They do great in that mix.  Your Peat/Sand/Perlite mix is a good airy mix and your plants should do wonderful in it.  The benefit you would get from planting the Venus Flytraps in a peat/sand mix separately is going to be so small you might not notice any difference.  Also, a sandier mix may not really be warranted in pots since you want more moisture holding property in pots.  Even though they grow in very sandy soil in nature, a big natural Pocosin bog is a very different thing than a container.  Also, flytraps very much like bigger containers, so having them intermixed with the other plants in a large planter is very beneficial.

The winter immersion thing for S. psittacina can be beneficial.  For that reason it does make sense to pot those in peat/sand since it will help weigh the pot down.

We've used perlite with peat moss almost exclusively for decades.  We have a very good source of perlite that is igneous rock based so it doesn't leach out any other compounds.  I'm not sure where that 20% figure comes from or is based on.  I do know here in the US we have a couple other companies that make perlite that are reported to have fluorides in them, and that it can be a problem to some plants.  We've never had that issue.

I'm a huge fan of the dark chocolates with a high cacao content!  Thank-you!

Good Growing!
