One of my biggest gardening revalations came from my favorite gardening author, Gayla Trail of You Grow Girl. She says ANYTHING can be turned into a vessel for growing! I love this concept and have since repurposed dresser drawers, tote bags, plastic food containers, broken cookware and random wooden crates into inexpensive (or often free!) homes for plants. My husband has seen me several times while walking my dogs picking up cast aways from the curbside for new gardens!
As we moved into a different space at work I saw this concept in action and saw how giant part crates could house tropical plants...
Finished recycled parts bin of mother-in-law's tongue.
The parts bin was lined with plywood and an adhesive self healing paper (used for sealing around windows) was applied to the lower half to protect the wood from any water damage.
The bin is very large so several plants were used inside each. Plants are potted individually and sheets of styrofoam were added inbetween each pot. Pots were put in very close and were covered with moss to hide the styrofoam. On top of the moss large river rocks were added.
When watering the plant, it is only watered at the base of each plant to make sure the water gets into the pot and not the spaces in between (although if it spills the container is protected!).
I haven't tryed this yet myself at home, as my house is quite small but I'm keeping my eyes out for anything that could give this similar look.
