I'm curious...Do you use fill the bottom of your pots with?
Do you use anything?
I know many use filler on the bottom to lighten the load and bring the mix up higher in the container.
I use just plain ole bark mulch for many reasons and it does a superb job for my plants...That is in deep or large containers..
Some use styrofoam peanuts, others rocks..
What do you use and why?
