Phrag. Schroederae browning

[parasocks]

Hi All

Hope you well

A few months back I purchased a Phrag Schroederae. I recently noticed that the plant has some brown spots on the stems and some leaves and new growths. I have smelt it and it has no smell, I assume its related to bad culture on my part, I have been growing them outdoors and watering every 6 days or so. The media is moist but on the dry side. The temps are around 4-20 degrees C at the moment and its in bright indirect sun (we in winter here, heading into spring).

I am not sure if this is Rot and if i should remove the buds and leaves? It does not seem to be spreading but I am not sure. The Phragmipedium Paul Eugene Conray that I bought at the same time seems fine, no issues.

Any help will be appreciated.

Thanks

I'm only guessing, but I suspect the following: not enough watering and/or
getting water down into the leaves. Perhaps you might move the moss away
from the plant growths at the base of the leaves.

Thanks i will try that. Is it fine to grow them in a shallow tray of water?

Looks a bit like a pseudomonas infection to me, but it's hard to say for sure. I'd consider a copper-based treatment. They are typically sold as fungicides, but are pretty good bactericides, too.

Get some Dragon's Blood, sap of Croton lechleri.

Don't get the amazon Dragon's Blood. It is very poor quality.

I am with Ray subgestion. I have also observed same situation on my Phrags. To get rid of this problem I treated with FloridaMix (a mix of Aliette and Dithane).
But as these materials are difficult to buy Bordeaux mixture is a good alternative. Copper concentration must be around 500 mgr/liter.
