Do I have to use it???
Drainage!!! I am going to use a kiddie pool that is 8 inches deep. My bog is going to be soley a carnivorous bog garden and will be above ground. I have been told that I need at least 2 inches of drainge. I was recommended that I use perlite. I know that the drainage portion is to trap excess water and keep roots from rotting but will all the nuetrient from the soil leach away and go to the bottom of the drainage(depriving my plants)? Carnivorous plants really don't have large root systems and do not reach deep into the soil, so thier roots may not not be able to rot at the bottom if i don't use drainage. Still I am not sure if I should skip the drainage part. What do you think?
