Orchids 2023

Justin, your forest of flowering P. rothschildianum is a gorgeous sight .... but I see some leaves which are partial or complete rotten or at least brown. Do you know what caused it, maybe fungus ? And why don't you remove them to avoid health problems of you plants ?

I asked about that before, Rudolf.

Hi! Every year in spring and fall, some leaves on a few of my roths turn brown at the tips and die back. It is definitely cultural, either from low humidity in my growing conditions, or some kind of nutritional imbalance.

It is also a seasonal occurrence, and I don't have a lot of problems the rest of the year. The plants continue to grow so I don't worry about it too much. I see it as just one of many compromises with growing this species indoors.

I've had similar issues with leaf dieback that have greatly improved after treating for Glomerella with a rotation of Cleary's (Thiophanate-methyl) and Heritage (Azoxystrobin).

 

[Justin]

Thanks, I will have to check that out.

Glomerella is a species of fungus....

Glomerella is a species of fungus....

Yeah, I have had some fungal problems affecting some other plants, but I was always a little lazy about it.

So I think I will get more aggressive about treating this now.

Thank you all for the advice!

Holy crow. Wow.

I was also lazy about it...because I hate using chemicals, carry that one step further and I hated using chemicals in the house....
Love your "Roth Jungle"!

 

[My Green Pets]

Damn!

Holy crow. Wow.

Don't be angry BrucherT, but is it not usually a holy cow Maybe you could say rather holy raven (the tale of King Arthur). But it doesn't rhyme. Sorry!

Incredible! Indeed a sight any Bornean would cry with happiness!

Hope you breed some of them together for the continuation of this valuable species for the future.

Yes this year I crossed Canadian Club x Borneo. Later this summer I plan to do MM x CC.

 

[Tony]

I used some CC pollen on one of my Giant Wings x X-Hot too.

The symptoms on the leaves are a massive potassium deficiency. It can go eventually much worse when they spike/bloom or just after they flower. It is nothing fungal or whatever.

 

[NEslipper]

Quite a sight, and no small feat for an indoor grower, congratulations!

 

[Justin]

Another first blooming 'Rex Jr' x 'MM Best'



'Charles E.' FCC/AOS--I have three plants all in low bud.

 

[annica.jarvela]

Looking really good and beautiful, Justin. Nice red pouch. Interestid to see how the Charles E FCC/AOS is going to look like. Great job and healthy plants.

How often does your Charles E FCC clone bloom??

Well, last time was when I bought it in spike in 2012.

It is a healthy clone but a slow grower. Over the years the clump I bought separated into three plants, all of which are now finally ready to bloom again.
