BellaOnline Forums Home and Garden Orchids Phalaenopsis orchid leaf turning yellow

I am looking after some plants for a friend. One of the leaves on her Phalaenopsis ochrid is starting to turn yellow.
I was told not to give it too much water so I wait until the soil is dry ( about 8 to 10 days). It is in the same spot it always has been with same heat and light. The blooms look fine in fact another bud is starting to come out. Any suggestions what I can do or not do???
Thanks
ps. she won't be back for another 2 weeks. Will it die before then?

Phals do lose leaves as the leaf matures and dies. The other reason the leaves turn yellow would be crown rot and that is a serious problem. See if your friend has some Physan 20 or Consan 20 spray for her orchids and spray the orchid with this mixture. It contains a fungicide. It will not hurt the plant if there's nothing wrong.

Thanks, I will try that

Is it a lower leaf? Phals tend to lose a leaf or two on the underside when they mature. Don't get to stressed about it. It of natures way of 'out with the old and in with the new.
