Sick Vanda

[Jun]

Hi,
my vanda looks sick. It has rust-like fungus on the top 2 leaves.

I suspect that it could be some kind of fungus. Could it be crown rot? or sun burnt?

should i cut away the affected area?

please help me...

how long has been like that for?

looks like it is trying to outgrow a dose of crown rot[COLOR="Silver"]

Yes, I would cut the leaves that have the rot on them. Use a flame-sterilized & cooled cutting tool, cut into green healthy tissue between the plant and the rot. Leave it go for a day or two, dry, in the shade, so the cuts can heal. Resume careful watering (roots only) afterward, watch to be sure the rot does not return.

it been like that for about 3 weeks.

how far into the crown does the rot extend? I'd be inclined to slice it off as well.

You should then treat the plant, I personally use Potassium Phosphite as a rot preventative, if you can get yates products in Singapore look for Yates anti-rot.

Make sure when you water you keep the crown dry.

thank you.

i have cut away the infected leaves.

Will it grow new leaves? or will it become dormant ?

vanda are usually pretty resilient, and yours otherwise looks healthy. it should keep growing
