Have you called any landscapers in your area to ask them if they have any laying around?
Also, if you have wire laying around, it's easy to make your own:
Get an awl or large spike nail, WEAR heat-resistant gloves, heat the nail over an open flame and make equi-distant holes in the rim of a RIGID pot, let it re-harden, insert the HEAVY wire, use pliers to twist it into a hook, and there you have it - a hanging pot. I make a lot of my own hanging pots. ALSO, buckets make good hanging pots.
Thanks. I have a 1910 home and the wrap around porch demands ferns. Trying to over winter them is a pain but can be very expensive to replace every year - I 've cut it back to 5 along the front of the porch and not down the side.
I thought about making my own since this would be an ongoing spring plant that needs larger pots than are sold - with the fern. They are always root bound. I'm pretty crafty but wasn't sure a basic plastic pot would support the weight. If thought finding them would be an easy fix verses buying more pots (new). What gauge wire do you use for a plant that large?
