tolumnia care

Hubby got me an early Valentine gift yesterday: an adorable tolumnia in a 1" pot! Reading about it online says that it needs to be completely dry at the end of the day. I'm not sure how to translate that into daily or weekly care. Do I pull it out of its tiny pot to check that it's dry and then water in the morning? Should I spritz it or not? I'm not interested in growing it on a mount. It's in about 1/2" of bark right now! Any tips greatly appreciated.

For my 2 in 4" clay pots, I mist almost daily and water weekly. Very course/chunky well draining mix and lot's of light (catt)...

One is currently blooming, the other just sits there :-(

Good luck,

I have about 350 of the little babies. Most are in tiny pots with enlarged drainage holes in the bottom.
Do not know how you would grow them in Zone 4 but the fundamental is that the ancestors of the hybrids are twig epiphytes and they must dry between waterings. So I only water in the morning on a day that promises to be sunny.
Cold and wet in winter is a disaster waiting to happen.

I never mist them but they are in a glass-house where the humidity lifts at night and they dry out during the day. a fan gives gentle air movement 24/7 and a heater runs in the early morning in winter months so that the day temps lift a little bit.

Not much help really, but find a few versions of the culture notes and read up . Look at those leaves, they tell the story of not always lush and wet and maybe those channels funnel sparse dew to the base of the plant.

Here is another picture. The little beauties are in tiny pots.
Sorry, I no longer have an inches ruler, but i think on average the pots about 2inches deep and 1.7 inches wide.
I reduced the size of plastic pots.

They grow well on tree-fern mounts but I prefer pots for convenience at division time.

I know that they are regarded as difficult, but worth a try if you are space challenged. Cattleyas are grown on the benches below.
