Question
My phalenopsis orchids are doing much better since I stopped watering so much.  The new leaves are healthy.

The old leaves are still droopy.  Do I cut them off?

Answer
Marilyn, the droopy leaaves will not recover because the roots serving them are likely dead-- you may cut them off.  Reducinng watering is the second best thing you can do, so, good for you.  However, even better, is to repot your plant in a standard orchid potting mix. Obtain a bag of orchid potting mix and place a quantity in water to soak and the rest set aside for future repotting.  While soaking the new mix, unpot your plant and reinse off the roots.  You will undoubtedly notice some roots that are mushy and have collapsed.  These should be removed before repotting and are the cause of your droopy leaves.  Healthy roots are firm and turn green when wet as they contain chlorophyll.  I recommend that you use a plastic pot with lots of drainage holes in the bottom for drainage and air movement through the potting mix.  Do this in an area where the new potting mix, after being added to the pot, can drain freely.
