You've put the plants into your garden. It's time to clean up... can you recycle the plastic flower pots and trays? It's tempting... they've got the recycling arrows on them. But... please don't add them to your recycling bin.
We are able to accept all plastic bottles with necks. What about those pots and trays, then? Gardeners are often happy to take these for use with their own seedlings. Otherwise, please put these items into your household trash.
However, if a plastic bottle has held hazardous contents -- that purple bottle in the photo is labeled "Wasp & Hornet Killer" -- then please put the empty bottle into your household trash as well.
