I edited my last post, but not sure if people will see it, so I'm posting here.
I planned on putting the trees in a bucket of rain water for storing, but since most people are picking up same day, maybe it's best to leave the trees in their original bags until they're picked up. If you do want me to keep the roots in water, or any other request, feel free to let me know. Also, I'm near a Home Depot if you would prefer to pick up in a public place.
