Thanks All for your advice, unfortunatly I live in the UK where
temperatures are cooler, so the orchid is on my kitchen windowsill. I
has some buds coming, but it has lost 2 leaves & another 1 is wilting.
I read it could have rotting roots. Should I water from the top or
bottom ? I have only been giving it a cup a week, pouring the water
away at the end of the day & the medium has looked dry each week
before watering. Should I repot it now or when it has finished
flowering ?

Please help

Thanks Leonie
