Cattleya Laurie Lynn Westenberger

A rescue may or may not sprout. A backbulb division will likely sprout and will often skip that survival mode year that yesterday's Lc needed.

The Cattleya Laurie Lynn Westenberger in the Sonoma collection is a good example. Eight months ago I divided a fairly healthy plant and got two lead divisions and three backbulb divisions. All of the backbulb divisions sprouted this spring and one of them is ready to be moved out of backbulb status.

The new growth is well developed and it has strong roots.All the old roots and the older backbulb have been removed.This was a two-pseudobulb division in rock. Both were in good condition but with no live roots. I cut the dead roots to a length of a little over an inch to help hold the plant in place. It is important that the plant not move around in the pot.

Once I had removed the dead roots from before, I decided to also remove the oldest pseudobulb. There were no live roots and the leaf was broken. The new roots were strong but it might be better to have the new energy go into new growth. Mouse-over the picture to see what went into the pot. Always mouse-over pictures, lots of them have a pop-up.

Is that light spot at the base an eye? I'm hoping it is.All that remains is the question of what to do with the oldest backbulb. With no leaf and no roots it is not a hopeful sight. The easy answer is to toss it. While this is not a rare plant, being registered in 1958 makes it historically interesting. And the flower can compete with any modern hybrid.

I might be imagining an eye at the base of that pseudobulb. No matter, I am going to try for a second sprout. It is going back into a pot of rocks where it will remain until it sprouts or it turns brown.

  1. Is a pseudobulb with no roots any more likely to root if there is a leaf present? i.e. I'm trying to decide whether its beneficial to leave or remove old beat up, split, leaves.

  2. Looks like an eye to me as well,Richard. Hope it sprouts!

  3. I usually leave a leaf on if it is not broken. It may reduce the "sproutability" a little, but I let the plant decide. They will often drop the leaf themselves.

    In this case, it was broken and already weakened by the first sprouting. This pseudobulb will remain part of the sprouted plant any longer than absolutely necessary.
