Numbers

Lastly, a person that wants to try Disas should never start with just one plant. I don't know why, but Disa culture is so imperfectly understood, that you can provide ideal conditions to a group of 10 plants and you will see 4 of the plants just grow like crazy  while 5 will just kind of sit there and grow slowly and the one remaining will die. If you are doing everything right, the 4 plants that grow like crazy will put out 10 - 15 offshoots by the end of the year so you will still have increased your population but if you just start with one, for sure it will be the one in 10 that was going to die no matter what you did to it.  I know this sounds a bit off the wall, but I'm really serious when I say that you need to start with a small population and not just a single plant.
