Hi all,
Happy New Year! (First visit of 2023.) I'd be very grateful for your advice...
I recently bought this gorgeous Phal at the supermarket. I noticed at the time that it had some marks along the midrib of one of its leaves but I assumed the damage was mechanical. I've noticed since that the yellow marks have grown in size (please see pictures 1&2) and I'm concerned it's a fungal infection. Moreover three more of the leaves have dry/yellow patches along the midrib as pictured (though not the newest leaf, which is looking healthy at the moment).
I wondered, is the plant rescuable (I hope so!) and, if so, how should I treat it? I've read online that one should remove all affected tissue and then apply cinnamon to the cut surfaces and spray the plant with hydrogen peroxide. The problem is, this would mean removing all but one of the leaves if I was to play it really safe. Would the plant survive that? Or is there a different/less drastic treatment method I should use?
Please note, the dark spots in the pictures are shadows cast by buds. The picture of the flower is only included to lift the spirits!
Thanks in advance for your help with this!
