You have given me an idea on how to hang and feed on vanda when I buy one thank you very much. Yours looks beautiful

Plus I will be hanging mine on a shepherd's hook

Nice vanda's very nice vanda's happy growing

They look wonderful & I have to agree with Libby on your set-up. It has given me some ideas to try out with mine. I live in an area with 30% average humidity & I just can't keep up with twice daily watering / spraying. I've got a couple of those hanging baskets that I planned to use for cymbidiums.

Thanks tropic. They were actually raised in Perth would you believe. Pretty much just out in the yard under shade cloth. Must be tough cultivars.

The terete or semi terete vandas are the most bullet proof orchid I have. They have been exposed to over 100 and down to the high 20's. both in F. They have been buried under hurricane debris for months and found unscathed. Mine climb trees. Up around 30 feet.

I have been misting them daily with kelp extract to help with cold tolerance, though we have been having a very warm winter this year with minimum night temps of 10 or higher and bright sunny days in the low 20s.

kelp is good but i wonder if daily is too much? I give mine maxi-crop, every 2 weeks, a Norwegian seaweed juice. I think similar. 10 is an executable low temp. I heat lower than 10 or 50f. What about summer? what are the highs and lows. And how is your humidity?

Thanks Wikipedia...

Sharing a similar climate to Perth, Mandurah has a typical Mediterranean climate (Köppen classification Csa) with hot dry summers and mild wet winters. During summer (December to February), the average maximum temperature is 27 °C (80 °F) with an average minimum temperature of 19 °C (66 °F). At its extreme it can get very hot, often having a couple of days exceed 40 °C (104 °F) in the latter half of summer. In winter (June to August), the average maximum temperature is 18 °C (64 °F) with an average minimum temperature of 9 °C (48 °F). Mandurah's proximity to the ocean moderates diurnal temperatures somewhat, with temperatures a few kilometres inland often 4 or 5 degrees warmer during summer days (or cooler during winter nights). Frosts are very rare as a result, but do occur annually around suburbs such as Greenfields.

Humidity is generally low, summer is a dry heat. I do spray down my growing area daily in summer and also keep a lot of potted bromeliads/foliage to boost humidity.

By low I mean around 40-50%.....It's dry.

I indicated that I heat my vandas 50 and lower. That does not include my terete vandas. They are way too big to move or heat. They take what comes. Are all of your vandas semi terete? Non terete vandas may not be happy there with your lower humidity. Not sure. I am sure that teretes have a broader range of weather to tolerate.

The two I have outside are semi-terete (actually quarter terete I think).

The ladies I bought them off had lots of Vandas, but they were crosses with coerulea as a parent as well as semi-teretes and V tricolor. The bigger one has a new infloresence which is continuing to grow. Hopefully that's a good sign and not it's last-ditch attempt to procreate before keeling over.

All my others are grown inside on the windowsill in glass jars, though most of them are reportedly "temperature tolerant" as they have V falcata as a parent.

I think you have found an answer of how to grow vandas in a dry environment. #1 is to narrow down which vanda you will grow. Just like you have been doing. I wonder if you tried to grow a typical non terete vanda how it would do. Might be too much of a reach. Regardless it is impressive to see them bloom in your relatively dry climate. Well done!

New spike on JvB x Bangkok Beauty.

Green on the roots is a good sign. When they're all white it means too dry/too little humidity.
