New Cattleyas; Aloha Case & Hazel Boyd

[SADE2020]

Hello!

Anyone could give some feedback or advice on culture for these two Catts, please!

[Roberta]

once the weather warms up, Hazel Boyd will be very happy outside. (That's where I grow mine)

C Aloha Case is Mini Purple x walkeriana, making it 3/4 walkeriana. So I'd suspect that C. walkeriana culture would be your target.

Nice plants! No specific experience here

Hey Roberta, a newbie here, would you recommend putting it outside in the weather of Córdoba, Spain.
I'll try to upload a pic with the weather from last year (In Celsius)

Thanks!

Wait until spring, when nights are reliably above 12 deg C (55 deg F).Then it can acclimate through the full temperature cycle - next fall, when it gets cool, you can leave it out at least until temperatures go down to 4-5 deg C,, short times lower OK. If it is rainy and cold, keep dry - a dry orchid can tolerate much lower temperatures than a wet one. But acclimating it to the low temperatures is important... if you put it outside now, the shock would be severe. (That is what I do when I acquire plants in fall and winter that I know can tolerate cold, unless I know that they have already experienced it. I protect them until spring, then put them outside where they can stay)

Oh thanks!
Right now I have it inside with daylight + led light.
I was wondering more towards summer, would it tolerate the extreme heat? We have days with 45-47°C
Sorry if it's a super newbie question, I only have phals until now hehe

I think that with shade it will be OK with the high temperature. Again, it will have had time to acclimate.
Actually, an excellent question - that is HOT. But as long as it doesn't receive direct sun at those temperatures, I think it should be OK. (Direct sun is the enemy... it can make the local leaf temperature high enough to burn. Catts are tougher than Phals, but everything has its limit) If it gets that hot, do observe the plants carefully... you may have to intervene. I can't advise from experience since it never gets that hot where I live - the record here was 42 deg C (109 deg F) ... and I had no damage, even to much more fragile plants such as Pleurothallids from cloud forest. I did water 2 or 3 times a day when it got that hot. That helps too.

Ok, thanks a lot! I will try to grow it outside since its a relative large plant, and see how it goes when the weather is a little better at night.
