Sometime in December I am going to move all my Sarrs to a 14" garden bowl. I already have done this with my VFTs. My question is, should I punch out the drainage hole in the bottom of the pot, or leave it undrained? I took the drainage hole out of the VFT pot, and I haven't had to water it often at all. So I'm wondering, with that size bowl, will the peat naturally hold enough moisture so it doesn't need to be drained?
