I only have to look at orchids and they die...
Hope the cat is better soon.
The cat is not a well child, let's just leave it at that. Hyperthyroidism, old age.....I give him lotsa love and as good a life as I can possibly provide.
As I said before, Orchids purchased anywhere, whether it be the supermarket or at a fancy plant store, are all "churned out" of a nursery like on an assembly line. Lord only knows what industry secrets they employ, but they're not good from what I've observed.
The best thing to do when you get an orchid plant home is to cut off the bloom stem and enjoy the flowers in a vase.
Now comes the nightmare, take the plant out of the container and carefully assess the condition of the roots and the rest of the plant.
Phalaenopsis are always touted as "popular" and "easy to grow", which is BS. They're popular but far from easy, especially if the roots are rotted which is more often the case than not.
Examine the entire plant and check for algae growth, fungal infections, insect infestations, and other unpleasantries.
Cut off the rotted roots and disinfect the entire plant and remaining roots liberally with 3% Hydrogen Peroxide.
Actually, even before all that, you have to remove the hideous rotted coco coir (coconut husk fibers) from the root system.
Coco Coir is very popular now for almost ALL plants because it's so cheap, but it essentially chokes and suffocates the plant's root system and makes a mess of everything.
I've spent hours soaking the stuff off in buckets of water and dumping it down the toilet, repeat, repeat until you get as much as you can off.
The Orchid plant will then go into deep shock, after having all the rotted roots removed and only a few viable ones left.
At this juncture, you have to begin attempting to coax the plant into growing new roots, that's first and foremost.
Don't pack (expensive) sphagnum moss and bark around whatever roots remain because 9 out 10 times, the remaining roots will rot because the Velmen membrane that envelops the roots is already weak and prone to rot.
I spent months soaking the plants in water mixed with orchid food and rooting hormone, once a week.
Some pants survived, some didn't....most did actually.
The plants were then left in open-air containers and I finally began to witness fairly robust root growth.
I'll take pictures of some of these plants with the new root growth so you can see.
Phalaenopsis are rather touchy about aeration and hydration, they do better on the drier side and prefer lots of air circulation.
I even made my own planters out of plastic coffee cake containers from Trader Joe's and just punched tons of holes all around.
The Oncidium likes lots of moisture, so it has done remarkably well, sphagnum moss and all.
Class dismissed, there will be a short exam. Attendance is required.
