It isn't neccesary ken, but it is not advisable to plant neps with sarras and VFTs in the same soil. While neps like damp but well drained soil, VFTs and sarras like soil that are wet completely. Also, they have some different soil requirements, like VFTs don't do so well in a mixture of nep soil like pumice, lava rock and etc. If you grow all of them in LFS, then you have to watch your watering for the neps cause LFS holds water and too much water can cause your neps to have root rot. On the other hand, VFTs and sarras will need to be watered more frequently. If you follow your nep requirement, then it is most likely that your VFTs and sarras will complain of lack of water.
