Planting in big container Q
Hi all. I bought 2 gorgeous containers for my deck. One of them is really big (and heavy!)and I would prefer to not spend the money on potting soil to fill it up completely. I am just going to put some perennials and annuals in it, so the plants won't need the container's entire depth for their roots.
Can anyone offer tips about what I might put into the bottom of the container below the potting soil to fill up space? I was thinking about pine bark mulch, but then thought it might end up being a slug haven at the bottom. I would prefer something kind of lightweight (but sturdy)so if necessary, I could scoot the container across the deck as needed (I might put those furniture movers under in anyway since it's so heavy even without being full). But whatever goes in the bottom would have to withstand the weight of growing mix.
Any tips are appreciated. And I would love to hear also what you put under this type of container (concrete?) to help protect the deck surface from water damage.
Here's a pic of the containers...I cannot WAIT to plant them!
