    Default Vanda coerulea leaf spots

    Hello everyone!

    My Vanda coerulea has some very unsightly leaf spots that I believe are fungus or bacteria. No idea how it got this! I've sprayed with a Physan 20 solution with little effect. Any more recommendations?

    I would cut off the affected leaf sections and dust the cuts with powdered cinnamon. And sterilize the blade.

    i've got a coerulea doing the same thing. i've cut off the leaves and the tips where it is cut start to dry up and die. i've used anti-fungals, and been careful watering and no luck, the leaves are slowly dying towards the stem. only a few leaves near the top. i've gone and bought another now just in case it kills the top of my plant. no other plants near it have been affected. it was doing so well at first. i thought originally it had sun burn, but the spot kept getting larger. then another leaf. it is now starting on a 3rd leaf i think. and i have cut 2 leaves back twice trying to get ahead of this infection. no luck. i have not used cinnamon on it, but have used it before with bad luck... i find it can burn plants. i have dipped the plant and it's treefern pot into a very mild bleach solution, no help, no harm.

    I sprayed with a Physan solution and also made a paste with some cinammon. Not sure which worked but the spots have dried up and aren't getting any bigger. Could also be the sunnier hotter weather? Anyway just glad it's doing better.
