Not everyone has a pickup truck or other vehicle to make it easy to haul a cut Christmas tree home. So somebody invented the plastic netting that most nurseries wrap around trees so they fit inside cars or on roof racks.
The problem with the netting is that the plastic is virtually indestructible and non-biodegradable. Plus, if it ends up in the landfill, it's a dangerous trap for small animals.
Luckily, getting rid of your tree netting in a responsible manner is easy as pie. Simply bunch it up into a small wad, then shove it into a recyclable plastic grocery bag. Knot the top of the bag to keep the netting inside, and toss the whole shebang into the recycle bin at the grocery store on your next trip. Voila! What could be easier!?
I've long agonized over the netting problem -- even eschewed the convenience at the risk of a somewhat frazzled tree. Doing without the netting altogether is still the better way to go, but if you can't do without, you now know the next best thing.
