Arachnis Flos-Aeris

[DavidK]

Hello Again ,

Here I am going mad again buying orchids that I like but don't know much about , this time it's the Arachnis (Scorpion Orchid) , I had been looking for one for ages and managed to get a cutting after bidding on ebay , the plant arrived , with good aerial roots & good color BUT ! now the bottom leaves are starting to turn yellow to almost half way up the plant , it's about 24 inches long .

I know the plant likes full sun & high humidity but it seems to be failing .

I do spray everyday with rain water which I collect in a large bucket which I use for watering my other orchids because I heard somewhere it's best .

As I spray the velamen turns green so I know it's absorbing the water OK .

I have the plant tied to a fiber pole in a Vanda basket , just because it didn't look right just hanging there .

This is the first "cutting" of an orchid I have tried to bring on , is there anything I'm missing doing ? or should I do something "extra" ? I promise I will try to find out more about what I'm buying next time ops:

Thanks for any tips on this one

As Always ... David
