Question
Hi Wayne,
I bought this orchid from a hardware/garden store and have had it for about 7 months. It was gorgeous when I bought it but since then has lost it's flowers, and doesn't have the healthy leaves it had before - they're droopy, one of the top ones has a split down the middle and the under-ones are a much lighter shade of green.
It was my understanding when I bought it that they're difficult to take care of, or that I at least had to be mindful of it's watering schedule and what not, but I need to bring this thing back to life! I've just been feeding it water and it's medium is moss and bark.

Thanks for anything - really,
Katie

Answer
Katie, most important of all at this time is to repot the plant in a fir-bark based orchid potting mix and a plastic pot that has lots of drainage holes.  You should be able to locate a hobby bag of it-- perhaps where you got the orchid or at some other garden store.  When you have the potting mix,soak it for at least a half hour while you are unpotting your plant.  Rinse the plant's roots and you will notice some that are mushy and/or stringy.  These need to be removed as they are dead and the reason your plant is looking sick. Hopefully, you have some healthy roots (they are firm and turn green when wet).  Place the healthy roots into the pot and add fresh potting mix, tapping the side of the pot to settle it about the roots.  Add the potting mix until it is just below the leaves and about one inch below the top of the pot. Depending upon the extent of the root damage, the droopy leaves may eventually turn yellow and fall off.  You are now concentrating on growing new leaves and roots in this fresh potting mix.  

Of all the factors that make for happy phalaenopsis orchids the most important is the right kind of potting mix.  Phalaenopsis orchids should be repotted after each flowering.  Grow it in an east facing window, if you have one, and be patient.  As house plants, phalaenopsis orchids do best when they grow in an environment similar to their wild tropical environment.  In nature, they grow in, or on, trees where their roots are exposed to air as well as moisture.  Thus, unlike with other house plants,  they need to have a special potting mix that allows for good drainage and air flow to the roots.  Unfortunately, as sold, orchid plants are in a potting mix that has already started to break down, causing varying degrees of unseen root damage. Water your repotted plant once per week thoroughly.
