Replacing cracked clay dish garden
I have an old clay (curved bottom --no drainage holes) dish garden pot about 5 in high, 13 in wide that has decades old ivy-pothos-etc mixed up vines of 3 types growing out of it and entwined over a metal and glass multi-shelved 6 foot tall shelf.
The clay pot from dissovled salts in fertilizer I've used roughly monthly over decades until I stopped doing that caused the clay pot to have leaching spots, not so bad, but now one whole back edge has cracked through and through top to bottom, so the question is simply, now ---how does one subsitute out the existing dish garden and put in a new one when the vines are all entwined over the metal parts of the shelves? Cutting it off would kill the plant separating roots from the leaves, some of the sections of vines are bare only because the new ones blocked light from the old ones.
I've discovered that short of buying a full new "dish garden" a search of the web does not produce anything shallow like this and wide that is sold "empty" for replaceing dish gardens (there are two more that I could do with replacing but they don't have the vine problem this does so I could use 3 dish gardens from some source). but the garden store only sells them filled, not empty!
Thanks for all your help!
