Mounting orchids for the first time

im in!

are you orienting it vertically? i am unclear by what a flat log is, forgive me

[davidg]

No, I had a round log - a cylinder about a foot long, but thick, with corky bark. I attached it in the middle. Right now I have so it is on one side, facing the light, with the log horizontal. I can rotate it so that the plant hangs vertically - I figured it should have a chance to attach a few roots first?

Remember, this species wants to grow vertically, with leaves hanging downward. (The stem is floppy because it doesn't need to be rigid in that configuration, why waste energy with growing hard tissue?) Also, it can produce new roots at nodes where it appears to branch - so those should be in contact with the mount as well. Water daily, and I think you'll find that it roots nicely, and very possibly at more than one point.

Thanks for that. I did notice a root coming from a node on one stem, which is why I left it vertical, until that root took hold. I could add an extra tie and hold that node down - I'll do that. Water every day for sure. The next weeks have highs about 15 to 17, so we should see some growth, and on the others that I am steadily getting mounted. The Cattleya bowringiana is a bigger plant, so I decided to put it right on the tree. When I took it out of the pot it had lots of root activity at the growing end, so it should take hold fast - I really tied it down tight in a slight hollow on the trunk, to accommodate the big mass of older, intertwined roots from potting, with some sphagnum over the roots.

It was a picture of it blooming in Kirsten Llamas' book, 'Tropical Flowering Plants' that got me going in this direction. She has a beautiful picture of D.lindleyi too, and D. bigibbum, which unfortunately I haven't been able to source yet. All growing right on the trunks of trees.

Thanks again for all your great advice, and take care out there!

I have it on the side right now, and it is very secure, (I did bonsai back in the 60s as a teenager), but I was also concerned about light. But I think I will put a hanger on it and put it up higher, with the plant hanging down - thanks for the guidance (and enjoy the pickles!)

i almost never mount things on the top of a horizontal branch. this is somewhat aesthetic but also because they never grow that way in nature, always slightly off to the side or underneath a horizontal branch or on a vertical face.

your method of attachment should be strong enough to hold the plant in the orientation you want to be in, think a little bit of bonsai culture.

if you are concerned about the plant being steady in a vertical orientation, i would lash it on tighter

Hi, David -
First, that's great news about the plants that are rooting to your tree. With regard to the C. bowringiana... until it starts root growth, it doesn't matter much what you do... the plant is running on reserves. I just looked at one of my C. bowringiana plants - just now starting new growth, I don't see roots yet. So this is very likely the right time to get it mounted. The dead roots aren't hurting anything, especially in the air where you don't have to worry about rot. You could clean off the old velamin and leave the stringy core of the root - which can help to hold the plant in place, and may be able to provide a little hydration too. But if you can get it mounted now, the new roots are the ones that will grab the tree. (The older good ones will continue to to do their job, but won't grow onto the tree) So the problem may just be timing - these typically root once a year, so you just have to wait until it is ready to grow, and that time is very likely now.

Thanks, I will do all that and we shall see!

[DirtyCoconuts]

stand outside holding the plant in one hand and the mounting method in the other....do not sleep....the second you see that root you DIVE onto the tree and strap it on!!!


HAHHAHA, id do exactly what Roberta said...generally new growth leads to new roots and that is the time to mount.
