Question: Cambria that does not bloom
I own a cambria orchid that I had taken from the nursery at 1E and it was not too good, I managed to make it grow, the roots are beautiful white and has several speudobulbs. then I decided to divide it because the speudobulbs grew in the air and the roots struggled to reach the ground. so now the two jars are both rich in speudobuldi and leaves and continue to make them, only that I have not yet managed to make them bloom and I do not understand why they are positioned close to the other phal that bloom regularly, they are fertilized by the spring (not very often ) with the fertilizer of the specific composition for orchids are currently at a tem. around 18 ° C but only spudobulbs appear. this time I tried to leave at temperatures around 13 ° C but I realized that the only effect was to do damage to the roots and then I put them back at 15-18 ° C. now I don't know what to try to encourage them to bloom. what should I do? what am I doing wrong?
Answer: Cambria that does not bloom
the orchids of the Cambria genus are hybrids, whose cultivation must be carried out following a little the indications for the species from which they derive, and in particular these orchids have very similar needs to those that the odontoglossum presents.
These orchids are epiphytes, and the fact that the roots come out of the growing medium should not worry us, as even in nature they do not live with the roots immersed in the soil.
I would say that the health of your plants is excellent, and the absence of blooms could be due to a couple of things.
First of all, it often happens that plants that are divided and repotted use their greatest efforts in reconstituting a good root system, in producing new leaves and in enlarging the pseudobulbs; for this reason it may well be that your orchids have taken a kind of pause from the blooms, at least for this year, or that they prepare the flowers in late spring, after the plants have recovered from the repotting.
It may also be that, as you may have guessed, cultivation temperatures are too high; in fact the cambria derive from species of orchids that are accustomed to a climate with a marked difference between the seasons, therefore (as with many other plants) if they are not subjected to a period of a few weeks of cool climate, they do not realize the passing of the seasons, but believe they are in a single long spring, during which they have already bloomed. For this reason in winter it is good to place the cambria in an unheated area of the house, or even in a cold greenhouse (or temperate, with temperatures below 12 ° C). The main problem with this shift is that the plants must be dry before they are moved, so that once they are cold, they do not suffer from excessive water. As with succulents, even Cambria needs less water the colder the place where they are grown; therefore in general it begins in autumn to reduce watering and environmental humidity for these plants, in order to place them in a cool place in a low humidity situation, otherwise the roots will suffer with ease from very harmful rots.
So, on the one hand you should wait, that perhaps repotting will delay flowering; in any case, for the next year remember to move the plants to a cooler place during the winter months, taking care to wet them only sporadically.
