Carnivorous Plants/outdoor butterworts


what mix of soil is best for temperate butterworts?

The soil for outdoor butterworts vary greatly.  For most varieties, you can use the standard mix of 1 part peat moss and 1 part perlite.  However, you don't keep the soil as waterlogged as you would with Sarracenia.  If anything, err on the side of having too much drainage than not enough.  You can increase the perlite (or sand) up to 2-3 parts to 1 part peat moss.  There's no "best" soil mix because a lot of it has to do with your particular watering method.  If you're keeping the plant in lots of standing water, increase the perlite.  If you're top watering on a regular basis and allowing the water to drain freely, use the standard mix.

Good growing!

No terrariums. No myths. No nonsense.
Just the straight facts from guys who grow and propagate
thousands of carnivorous plants each year.

Our focus is to help help growers diagnose a specific plant problem and offer solutions. For example:
  • Why is my sundew not producing dew?
  • Is now a good time to divide my Sarracenia?
  • Why are the traps turning black?
  • What's a good substitute for perlite?
  • Why didn't my seeds germinate?
  • How do you deal with pests?
  • Can you identify this carnivorous plant for me?
We no longer answer general, how-to questions that are already posted on our website or demonstrated in our DVDs. For general plant care, please read our care guides:
