What happened to my Mokara?

[nicki]

Any ideas?

Oh, no. It is a crown rot. You would probably need to cut the top portion off and treat the area with fungicide. Based on what I have learned from this forum, the Mokara will put out keikis when the mother plant is damaged.

Now thats a sight no orchid grower wants to see in their collection. But its common like root rot. Had this with paphs before I clocked why it occurs and lost a brassia and cycnoche to it. Crown rot pretty much hits the plant hard and is often noticed when its too late.Water has collected in crown and isolated from airflow. Cut below rot area. The leaf that is black will give you a rough idea as to where the rot goes down to by pulling it. It will slide out with ease. Plant will reshoot and or like Naoki said produce keikes. Another tragic learning curve for us and sometimes at the cost of a plant.

Yes it looks like crown rot.
Water remained in the crown for too long.

You could try plucking out the rotten leaf and clean/disinfect the crown area. Make sure to cut away any of the leaves around the crown that shows the infection.
If you are very lucky, the apical meristem is still not damaged and could continue to grow.
If the infection continues to spread, then follow the advise above and cut away the top portion of the plant to prevent further infection and hope to get keikis.

Cut away ALL black with a sterile knife or blade. Then dust sulpher powder on the wound. This works well for me and my orchids. Do this ASAP! Betty

I agree with everyone else, but, just because I have such bad OCD, I'd pull it out of the pot as well, check the roots, chop out anything rotten - both roots and crown area, drench it in fungicide, and I usually put cinnamon on open "surgical wounds" - smells better to me than most of the other stuff. Unless your plant is in a bad stage for repotting, you certainly won't risk harming it by examining the roots and getting it into fresh medium.

Safe to say the diagnosis is unanimous Thank you everyone. This was outside all summer and doing so well. I didn't increase airflow enough when I brought it inside I guess. Must have been sloppy with watering it too. I'll operate later tonite and hope for the best.

Excise all the brown...treat the crown with peroxide or physan. Try and find the fungicide Banrot. The other systemics I would recommend are pretty expensive. All is not lost. PM me if you need directions and places to purchase.

I agree that a full recovery is quite possible. I have seen it done right here on the Forum. Good wishes and good luck with your Mokara! AL
