Thank you so much for your advice BigBill, Will C, DaisyL and sallyg. I really do appreciate it. I am trying to tend to it by using the watering method advised here. A few more queries please while I try to understand my Phal better...
It's quite hot these days in the UK, and within one day the moisture seems to disappear from the bark. Should I be watering 2/3 times a week while I am trying to revive it, with the potting mix as is?
I plan to repot the Phal with the right potting mix, as advised. Can I repot the Phal while I'm trying to bring it back to health? Should I snip off the withered roots when I repot?
Wrt an apt position for my Phal, I don't have a North facing window in the house. Would a North-East window work or is that too intense? Also, the flower spike has turned completely brown and dry. Is that ok?
Thank you so much in advance!
