Question
I have two orchid plants, one is large and the other a mini version. The smaller one is dying i think, the last few flowers are wilting and there is no sign of new life, the plant is a vibrant green though and sits in the living room away from the window but still manages to get light. Do you know why its not re-flowering? will it re-flower or is it dying? i did notice my mother over watered it the other month and it was water clogged, started to smell weird but i dried the roots, but could this of caused the flowers to die so many months later...?
And now my larger orchid. I tried to save it when i bought it. its was winter and the cold had got to it, there were still some flowers but they died after. i keep it by the window in the living room, i cut some stem back to an eye where it looked like it may grow again, on one stem there is no grow but now on the other stem there is some but it has been this way for about 4 months now. The leaves are becoming floppy and one large one is pale green with spots where there is lack of green on it. i think this leaf has been there since i bought it, but the smaller leaf that is becoming floppy is new... I repotted it a few months ago to a larger pot thinking it may help with the leaves and the new growth, but there hasn't been much change. is there anything else i can do? what do you think i should do for both plants.. please help i'd hate to loose them.

Answer
Aleshia, I'm sure you recognize that here may be a difference between the wilting of the flowers and overall plant health.  Phalaenopsis flowers last 3-4 weeks.  A plants may actually be in flower for a couple of months because flowers don't emerge at the same time and new buds may form as old flowers fall.

Most phalaenopsis plants flower annually at about the same time each year-- if the plant is healthy and gets sufficient light. A reason that a plant doesn't reflower when it should can be insufficient light.  A vibrant color may make for a good looking plant but may reflect insufficient light for flowering. Leaves need some brighter light during part of the day and this will result in the leaves being more yellow-green.  Place your finger or another object between the source of light and a leaf.  You should be able to make out a shadow on the leaf.

You indicated that you had repotted.  You should have used a plastic pot with lots of holes in the bottom and a standard orchid potting mix.  Also, an important function of repotting is to check the health of the roots.  Mushy or stringy roots are dead or dying roots while firm roots that turn green when wet are healthy.  Remove the unhealthy roots prior to repotting.  Unhealthy roots will cause floppy leasves and leaves that turn yellow and fall off the plant. If you have healthy roots and repot to the proper pot and potting mix, it will take 3-6 months to generate new roots and the new leaf(s) that arise from them.  

I hope this gives you enough to go on.  If not, feel free to clarify or ask for clarification.   Thanks
