Cymbidium 'Starman' newest leaf on new growth browning from tip down
Default Cymbidium 'Starman' newest leaf on new growth browning from tip down

Hello! 1st time reaching out on this sort of thing, so here goes..

As of June 8th all my of my orchids were put outdoors, in dappled shade. I live in Connecticut. It has been pretty hot, quite humid and rain at least once every day, just about. I noticed the newest leaf on this new growth on my Cymbidium 'Starman' was turning brown, starting at the tip and working down, about a week ago. I used sterilized shears and cut it away, that's why the tip is gone, thinking whatever is happening maybe could be stopped. Well it hasn't stopped. I'm very concerned. Any ideas what is happening to the leaf here? I just took these pictures. Thank you!!

hey yon, really not sure if I'm the right person to help as I'm not really sure what is going on with your plant.
I'm a firm believer that most problems start in the root zone.
You've sterlized an cut away the bit that was dying on the leaf but it is continuing which indicates the plant is more likely severely stressed.

Daily rain can lead to the substrate staying too wet which would be my first thing to investigate.

Any roots that are mushy should be removed if that is the cause. Then rinse the plant and repot it into new fresh substrate.

Adding airy substrates like lava stone, lecca or charcoal can help drain the pots during heavy rains but in turn they need to be watered more when it doesn't rain. That's a decision a grower needs to make whichever suits best.

How large is the plant? What the potting material? How large is the pot?

I believe it's a type of brown rot; in cymbidiums it usually occurs when water stagnates in new growths--established growths are typically not affected. You will usually see the central leaf of the growth begin to brown from the tip and proceed down to the bulb, about 50% of the time subsequent leaves will begin to do the same thing. If you gently grab the affected leaf and give it a tug, it should completely come free from the developing pseudobulb. The upside to this is I've never known it to be fatal (at least on any plant in my collection) as it's easily cured by cultural means--ie when watering: a. Don't water overhead unless you do so early in the day [ie before 8am]; rather flood the pots with water by watering directly at media level & b. Some species and hybrids are more prone to this condition than others--in my collection, anything with a large percentage of pumilum in it is suspect--so be proactive and flag those pots so you pay extra attention to them [side note, I've found hanging them helps, as there's typically higher airflow [ie things dry faster] 5+ feet off the ground]
Hope this helps,
AP
