This mix is a bit more open than Venus Flytrap compost with the addition of perlite to the mix. However if planting an outdoor bog garden you may wish to top with Venus Flytrap compost or live sphagnum moss as the perlite can float to the top and look unsightly. We would recommend repotting every 2 or 3 years and dividing as necessary. The plants do get a boost from the fresh compost. Our mix contains peat moss, medium grade perlite and ellutriated granite sand at a ratio of 6:2:1. by volume.
