Imported catasetums acclimatation

[david68]

Hello,

I receive a lot of catasetums (young plants and divisions) imported from brasil last week and repotted them this WE.
Due to low temperatures and travel most of them losts their leaves and seem to be in a kind of rest period.
It's the first time i receive imported plants and i want to know what is the bests practices to acclimate them to my culture conditions (warm greenhouse)

Thanks

Hi david,

that's cool.. I am also a big Catasetum fan, and living close to each other where did you get your plants from? (Vitorino?) I will get some plants from Brasil in two weeks too (I will get them in Merlimont and bring them home with me).

so, as for acclimatation of Catasetum. what I have done in the past, is to keep the plants letting me know what they want (well, more or less ) Important is not to let them dry out too much. If they do not have new growth now, just try to keep them under relative high humidity. If they have started growing, water carefully until they re-start the growing. (if you have pictures of your plants, that would help a lot to provide more accurate advice!).

It is possible that the plants show some king of regression during the first year due to the change (specially if they are young!). However, they will get over that very quickly in the second year.

just curious, which species/hybrids have you received?

Hi Ramon,

Thanks for your help.
That's great to find a neighbour here (and bonus : a catasetum fan ).

Yes they come from vitorino and some come from preuflora. Vitorino was in France just before the Vaucelle show last week.
I've make a very large order to vitorino (60 plants). (I took the opportunity with his fantastic list).
I take a lot of catasetums (barbatum, cernuum, cirrhaheoides+escuro, cristatum, denticulatum, galeritum, gladiatorium, longifolium and macrocarpum) and some mormodes (elegans, rosea, speciosa, warszewiczii) clowesia(amazonica) and cycnoches (cooperi, lehmanii, pentadactilum)
The longifolium is a large division and the leaves are very impressive - 70/80 cm)
I also take a lot of rupicolous laelias, pseudolaelias and catts.
I was just a little bit disappointed by some plants which were very young or small divisions (1 or 2 PBs). And the low T° doesn't help. The leaves became yellow and fall, roots were dry and the new grows rot( I remove them and use some Physan). I pot them in sphagnum with a little bit of cork.
I have a good humidity level (70/80%) all year round in the greenhouse (hydrofogger).

By the way I think (and hope so) they will start again
The peruflora plants were more healthy.

PS : I also work in clinical research

LOL 60 plants!! you are worst than me.. :-))))) I've also placed a pretty large order, but will never come to that number!! 11 Catasetum, 1 Clowesia, 1 Mormodes, 2 Encyclias... at the same time, also some 2 Catasetum and 1 Mormodes from Mundiflora (I'll get them in two days) and some more from Peruflora (Yverdon) I did not order Cstm longifolium (even though I love it!) because at the time I was thinking of my limited space (growing indoors).. When I decided to buy a house and build a greenhouse (all of a sudden) it was to late already to change my order with Vitorino...

also in clinical research? don't tell me you are one of the 3 Davids I know here, and I did not know your orchids passion!!
