Trouble with Doritonaeopsis - Orchid Board

Tindomul · #1 06-01-2006, 04:49 PM

I got this Doritonaeopsis Luchia Roseherz x Dtps Sogo Toshibaone in the April Orchid show At Rockefellar Center, NYC. It has lost all its blooms and the spike has been turning yellow from the apex towards the base. Right now it is yellow up to the first bloom. Now that doesnt make sence to me. Why would the oldest bloom be the last to die??
The plant is in Sphag. moss and recently has been getting alot of morning sunshine. My east window get more and more sun as we get closer to June 21/22. Could too much sun be killin it? Or could it be rotting??

Here is a pic of it when I first got it.

Still awaiting an answer. The plant is doing great, new leaves, big fat aerial roots, but no spikes.

This plant is now known as a Phal...they changed the name and grouped the Dtps plants with the Phal alliance.

My phals (including 1 Dtps) are in a pretty shaded area. Not total shade but not in direct light at all. Try moving it, see what happens.

Thanks Sue. But remember I gave you the news that these are now Phals? In anycase, I will still need your help to rename it. But the big question is, what would make the youngest blooms die off first?

Actually, I didn't know where I learned that! Thanks

I don't have a clue about why that happened...maybe somebody that knows what they're doing will chime in

In the Phalaenopsis Alliance, a hybrid with (any combination of) Phalaenopsis and Doritis is properly known as Doritaenopsis - Dtps. RHS does not list a hybrid named Sogo Toshibaone. It does recognize Phal. Sogo Toshi. Sogo Toshi's parents are both Phalaenopsis, hence this is a Phalaenopsis hybrid. Perhaps this is the name change to which Susanne refers. If 'baone' is part of the name on the label, this could mean that the Sogo Toshi parent is a mericlone named 'baone' or 'A-One' etc.; labelling is not perfect. So far, Dtps. Luchia Roseherz x Phal. Sogo Toshi is an unregistered Doritaenopsis.

As to why the youngest flowers were the first to go, from Tindo's description, I'd guess damaged roots. I've been taught to repot every new plant so that you can inspect the whole plant - a difficult choice to make when flowers are present, but better to sacrifice the flowers and save the plant.

Hope to see photos of this season's blooms.

I agree with cneos about repotting all plants when you get them. You really don't know what's hiding in there. I have repotted every plant I've gotten the day it comes home with me. Many of them have been in spike, bud or bloom. As long as you handle the plant gently so you don't break one of them off, all should be fine.

I agree as well. One of my best Oncidiums was stuck in sphagnum and NO roots when I got it at Lowe's! I removed the blooming spike and babied it. It is in spike right now (3 spikes on two parts of the plant) for the second year.

cneo seems to be correct here but my thought is that when a plant is in bloom it takes a lot from the adult plant to keep the blooms blooming as well as keeping itself healthy to support it's babies. I am just wondering if it is not getting the right nutrients to help along the younger blooms, being they consume more of the plants energies to go into full bloom duration making the older blooms the weaker on the nurishment scale using less nurishment to keep them in full bloom. Just a thought

Tindo has this happened to any other chids? Thinking it might be reflecting on a previous post of mine about fertilizing!!

Dtps. Luchia Roseherz is a legitimate parent name; not so with Dtps. Sogo Toshibaone. As I mentioned in a separate post, RHS only has a registration listing for Phal. Sogo Toshi. When you confirm the parentage, you can seek permission of the hybridizer to register (name) your plant Doritaenopsis Tindomul1of9 or whatever you choose. Registering with RHS is similar to a birth certificate - parents are listed, dates of first flowering recorded (with photos), and the offspring is named. This name will be the same for every hybrid with the same two parents, regardless of how many there are or where they are in the world.

Visit Royal Horticultural Society - Plants: Registration of Orchids for more information on registering.
