Odm. grande pseudobulb

pikevi · #1 (**permalink**) 05-26-2007, 05:57 PM

I picked up an Odm. grande. It has only one ps. bulb which is green and hard. And 'species orchids' are so hard to come by!

I have not repotted it yet.

Is it saveable? If it is , are there any special steps I should take to ensure its survival?

Would it be better to leave it alone for now and consider re-potting sometime in the future?

Any advice, please?

A photo is attached.

Thanks.

pikevi

what i would do with the Odm pseudobulb is pot it up into spaghnum moss.

I strike all my back bulbs in spagh.

I hope this helps

Thanks fred.

I will do that tomorrow. I will also keep it in a low light but warm area.

I hope it survives.

Couple of questions:

1) does it have roots?
2) exactly what is written on the tag?

kmarch, I am not sure if there are roots. As per fred's suggestion I was planning to repot in sphagnum tomorrow at which time I would know if there are roots or not

I took a snapshot of the ID-tag.

I found a tonne of cultural info on the plant.

I think the official abbreviation for Odontoglossum is Odont.

Thank you, kmarch.

I got the abbreviation from the 'net!!. (source: http://home.satx.rr.com/vandas/abb.htm

I will use Odont. from now on.

I will check out the URL you have given.

When you unpot it, if it has good roots I would be inclined to put it back in regular mix. If no roots, try the sphag&bag and a bit of rooting hormone.

pikevi can you please keep us updated with the bulb as its a good way to start of an orchid.

I have also found over the years alot of growers will give you a back bulb to get you srarted they take time to strike and grow but well worth it if you have plenty of time.

Last year i was given a back bulb of Leopard Lady Mary Smith a cym now it has 2 new growths on the back bulb.

Grown in spagh.

I think this time next year i will have my first flower spike.

It is a slow way to grow orchids but whats the hurry

Sure , I will.

Thanks for the advice

I re-potted the bulb today. It had a fair number of roots , although some were dead or dying.

Cleaned it up and potted it with sphagnum and small coconut husk chips.

Since there were roots I took both kmarch' s and fred's advice.

I hope it is not planted too deeply

I find this sort of thing to be a challenge because if it is too deep the new sprouts will rot off from the moisture yet it is difficult to stabalize the plant in a pot when there are minimal roots and only one bulb. Having said that it does look a little deep to me. I dunno, because I find it tricky, I dont' do much of this sort of thing. What do others think?

I agree with you kevin.

I would lift the bulb and have the bulb so it just sits on the top

Sometime it can be good to put it in a plastic bag with some damp spag and seal it up.

I think its also Rossioglossum grande now.

Cory's right. The RHS has recognized Rossioglossum as the genus for this plant and hybrids.

Thanks _cor, kmarch

I will change the records again

Hi All,

Just took a couple of quick pics of my plant of grande. It has just opened in the last week. It was a bit of a fog this morning, so im not to sure how clear they will be.

Thanks _cor for the nice photos. I did not know the flowers were that beautiful when I got the bulb. Subsequent to getting it I checked on the 'net.

In the pictures ,your outside looks gorgeous

. I like trees, cool misty environment.
