Repotting a cymbidium

I like this cymbidium a lot. Here it is at its peak. The compact size can be misleading - cymbidiums have a lot of roots compared to other orchids. They're like Clivias or Daylilies in the shape of the leaves and the mass of roots compared to their tops. I have one cymbidium in the state of almost-rebloom, so I hope that means I'm able to grow them and they're worth the effort.

Here is was just before repotting. I thought about leaving it until the bitter end, but instead of being fresh and joyful, it looks sad now. Time to accept that and clean it up.

It came out of the pot easily. This was about a 1 quart pot. The original mix looks like a medium grade bark.

I love the mass of roots, like a handful of night crawlers. Massive amount of roots. At this point I also cut off the old flower spikes, to get them out of the way, and trimmed off any dead or broken looking roots with a sharp sterile pruner. There were not many bad or damaged roots. At the center was a tightly packed mass of sphagnum - probably what the plant was started in. I removed it. My theory is that it can be a source of rot when the plant is in my hands, as opposed to in a tiny starting pot in the hands of the original grower.

I wanted to use a pot about the same size, but with so much root mass, I moved it up instead. Some authors recommend cutting off the roots. I don't know what's best, but this is how I did the last one and it did very well and is about to rebloom soon.

Here's the mix I've been using for all of my orchids. Medium grade fir bark, some perlite, some oyster shell calcium.

Now I've added the bark medium, with lots of tapping and shaking and holding the plant in place. It was interesting that even with the mass of roots, when I poured the old medium back into the old pot, it filled it to within 2 inches of the top. The dead leaf tips are also pruned back. I sprayed it with neem oil, which I hope makes it more disease and insect resistant, and also gives the leaves a nice shine.

Before potting, I wrote a description of the plant and the date on the inside rim, using a Sharpie. That way I know what's what, but in an unobtrusive way.

Maudii closer.... closer....

Paphiopedilum Maudii.... So close! Audrey is that you?

Ready for "Little Shop of Horrors II" I think. Audrey is waiting. ALMOST fully open. Lovely! And the first Pahiopedilum that I have grown from a new start to bloom. Awesome!

Dendrobium nobile buds and bloom

I treated this Yamamoto-type Dendrobium nobile to outdoor chill for more than one month. It's pictured in other posts. NOw it's produced a bud at every node. What a treat! Now need to treat it nicely until blooms result.

I think this one is Dendrobium Spring Dream "Apollon". Purchased plant in bloom. It will replace another that responded to cold by developing rot at the top. This variety is reported on the Yamamoto website as warmth tolerant, so may not need the cold treatment.

Cymbidium

For the past month, I've been hoping to see the new Cymbidiums at Fred Meyer and Trader Joe's. And now, there they are. Last year's Cymbidium grew nicely, and a nice green one would be a perfect addition. On seeing this one, relatively compact and lavish blooms, plus fragrance, I lost my resolve to buy only the green one and added this. Getting it home, I noted tiny grey spots that wash off easily - mildew? or something from the air? Washed them off, and drenched with neem. We'll see if there is something to worry about.

This was the first one I saw, and added it before the others. Didn't buy it, went back to the store the next day then the next. So here it is. A little buyers' remorse here. Beautiful, big, fragrant flowers. I don't really "need" it. If "need" is the right word. Still, they are not a lot of trouble, outside spring through fall, including now. Only when freeze threatens do I need to bring them back inside.

That green one. This isn't the green one I had in mind. It's better. The flowers are more unusual.

The entire plant, flowers included, is much more compact. Better for a windowsill grower. Smaller ones are reported as less dependent on cool weather to bloom. Not sure that's an issue for me. They are always an experiment. There are too many beautiful orchids.

The brown-flowered Cymbidium from last year. She torments me with her slow, gradual unfolding. The two buds are larger than a month ago. I need to wait two weeks between looks, to see change. I discovered it had been knocked over and off its perch. No obvious harm. Outdoor orchids are looking a little borderline as far as mold and threatened rot, so I sprayed with neem. It's still in a sheltered spot, out of rain but on south side of house. With gloomy rainy days, I hesitate to call this full sun.
