Hmm... not sure if this is Erwinia or not but my Paph mentor -- Faan Kruger -- told me to take a pin, heat sterilize it and then puncture the spot to allow air in and that would stop the spread. Worked every time. I now do one better, and after puncturing the whole spray the plants down with 3%...

Expertly grown! Well done. I envy your skill.

I was using sphagnum in a basket. It didn't really like that either but it absolutely hated the lava rock and died.

If I understand your question correctly, the nitrogen concentration is what you would have if you followed the instructions on the fertilizer bottle. For instance, take K-lite. If you dissolved 1 teaspoon of K-Lite into 1 gallon you would have 150 ppm nitrogen. If your water source has N already...

Sadly, my jubilation was premature. The *******s came back. I eventually tossed out or let die the infected plants. I am now fanatical about quarantining plants.

A lovely flower on a neat little plant. I hope both traits carry over to its progeny.

There are tricks to increase ambient humidity around the plant without putting it in a bag. Option 1: Get a large plastic tub or jar, put some gravel at the bottom and place the plant pot on that. Put water in the bottom of the tub/jar. To keep fungus at bay, mist the setup with some 3%...

Kudos on the resurrection. I am spraying my Disa with normal Miracle Grow once a week (the things hate fertilizer) and it is going well. I got the suggestion and info from John Marcotte: 1 mL scoop per 1 Liter of water with 1 mL scoop of Epson salts. Spray the plants once a week and then flush...

Can you please give us a whole plant photo? Put something next to it for a size reference -- a small car or elephant perhaps?

Manganese deficiency? "Manganese (Mn) deficiency is a plant disorder that is often confused with, and occurs with, iron deficiency. Most common in poorly drained soils, also where organic matter levels are high. Manganese may be unavailable to plants where pH is high." From Wikipedia. Perhaps...

For those not in the know, the flowers appear as a horizontal rosettes. The flower isn't upside down.

Yes, of course, first bloom is upside down...

I would buy if something came up I was interested in.

That is a very good looking flower. Self it!

Very nice. Can we get a better photo of the growth habit of the plant? I wonder if crossing some nice whites onto tampensis could produce something like this but with nice sprays of white flowers?

Hello, Good news, the seller has offered a replacement plant at no cost. Anyone know of a source for Mefenoxam which doesn't involve buying a whole gallon? I don't have big collection and would rather purchase a small volume of pesticide I am going to use completely than store stuff that then...

Sponge rock, perlite, pumice, lava rock... they are all largely the same thing. Lava rock just has a higher mineral content while sponge rock is principally silicon. I am have excellent results with lava rock so far. Papsh (even seedlings), Catts, Restrepia, Masdevallia, Ansellia, Oncidiums are...

Lovely! What is the growth habit? Are the pseudobulbs close together and mostly up-right or does this plant sprawl out with floppy pseudobulbs?

I like your soda bottle idea. I am also using the 500mL tall narrow bottles for my small plants. I don't drink enough soda to have the big bottles so I use yogurt tubs instead. It's a very practical way to recycle -- even up-cycle -- the bottles. Well grown plants.

Awesome plant. I must get one!
