I save plastic grocery boxes all year long to use for organizing and storing small parts and miscellaneous goodies out in the barn. Re-usable plant ties, plastic nursery labels, extra pot feet, plant clips, small parts for my irrigation system, empty seed envelopes, zip ties, plant tags, plastic bags and anything else I want to find easily when I need it! These boxes stack well, are light weight and clear so it is easy to see things at a glance. And, I get to feel really smug about recycling and repurposing.
I also repurpose empty kitty litter buckets, which also stack nicely, have tight fitting lids and are large enough to store fertilizers and special potions, sand, cement, specialized tools and netting (so the occasional winter mouse doesn’t try nesting in it), to name a few. These large plastic tubs are another good reason to have a large cat – in case the moles and voles and mice (and occasional chipmunk) aren’t reason enough!
