Crown rot

(Anaheim, Ca)

My beautiful Phalaenopsis Orchid was growing. Beautiful roots new leaves. Then I noticed the leaves not looking quite right and turning yellow. I checked the soil for too much water the lighting and so on. Then today the top fell off. Crown rot. =0( Is there hope of saving her?

I instinctively blow away the water on the top of my phals for a looong time, not knowing if it was advisable but always thinking it will be way better that leave the water there.

Thanks to your reply I'll keep doing it with confidence now!!

Thank you very much!

Crown rot can be very hard to treat, because it can kill a plant so quickly once it sets in. The fungus will quickly spread through the plant's main stem and be lethal if untreated. I advise cutting off all the affected tissue, and a bit beyond. You shouldn't be timid about this: it's sort of like amputating a person's limb when they have gangrene. Cruel but necessary.

Then spray the plant with a fungicide, or dunk the top of it in hydrogen peroxide. A dusting of cinnamon can also help, as it has antifungal properties.

With a little luck, the plant will survive and recover. To avoid crown rot in the future, try to avoid letting water collect in the plant's crown, and blow it out if it does splash there.

Best wishes to your orchid! I hope it pulls through!
