The Dendrobium Crisis

[addictedcountryman]

It definitely sounds like crown rot- i have a huge mini lavender dendrobium that i watered in the shower and i kept forgetting to blow out the water. A couple of days ago, I noticed a lot of new growth. A day ago, I noticed a lot of black spreading and the new growth easily fell off. It also smelled stale. i had to cut off the growth below the infection with sterilized scissors and sprinkled with cinnamon. Act quickly- Jenn is right. fungus spreads very quickly.

What could have caused this?? I have been taking such good care of it and now it's trying to go the way of the dodo!

Is there a possibility the new cane was cracked or broken at the base? I accidentally damaged a cane on one of my dends a few weeks ago while watering. I heard it snap but initially it didn't break all the way through. I left the cane on the plant and restricted watering for a few days to allow the broken area to callus and then waited to see what would happen. The broken cane still looks healthy but dropped off the main plant a few days ago. Now I have one healthy plant minus one cane...and one healthy rootless cane that has the potential to produce new plants from nodes along the stem.

I removed the bad cane but I don't have any Physan yet, so I'm just patiently waiting. If it spreads any further, I'll have lost the plant, . But se la vi...

Oh wow, NewGuy. You sound like me. But I am curious about Ranchnanny's response about the Listerine...does the (reg.) mean the original listerine, not the flavored stuff? Good luck NewGuy.

[Ranchnanny]

Louez, yes use the regular listerine not the flavored. Use it full strength.

Thank you for the clarification. I'll pick up some.
