Question
I have a Phalaenopsis that my husband gave to me on our wedding anniversary. It was very healthy, has flowers and buds and has dark green, long leaves. I have experienced taking care of dendrobiums so i assume it should have the same care. I wrongly put it on direct sunlight and watered it everyday. I did not put any fertilizers because I am taking care of my baby (worrying i might poison my baby). After the last bud was gone, all the leaves turned yellow and died.  I tried to save it by putting it to shade and transfer it to a new pot (since ants have attacked it's roots). After the trauma, right now, it has 2 pieces of one-inch-long leaves and 1 piece 2-inch-long deformed leaf (looks like it was bitten by an insect or something). The roots are dried on the end and i do not notice new roots coming out. I want to save my Phalaenopsis, please help me! Thank you so much for your help.

Answer
May, it sounds like you have overwatered your plant leading to root rot.  It is great that you have some new leaf growth-- that means you do have a chance of saving the plant.  First thing to do is reduce waterinmg to once per week.  Next, I recommend that you locate a small bag of orchid potting mix to repot your plant.  When you have done the latter, soak a pot-size portion of the mix in water and, while it is soaking, unpot you plant and clean all old potting mix from the roots.  Then examine the roots for signs of root rot.  Rotted roots are "mushy" while health roots are firm.  Remove all mushy roots as they contribute nothing to the plant.  Having performed those two steps, locate a plastic pot that will accommodate the remaining roots and place the plant's roots well down into the pot before adding the new damp mix. Tamp the bottom of the pot on a hard surface to help settle the potting mix about the roots as you add mix.  When you have finished repotting, set the plant aside in an east window if you have one.

Phalaenopsis do not do well under dendrobium conditions.  They like temperatures 65-85 degrees. They tolerate morning sun or dappled sun.  If you summered them out you will need to carefully monitor them to be sure the temperature range is OK and they don't get too much light. Phalaenopsis are, basically, houseplants and prefer the well controlled conditions of growing in the window or under lights.  They prefer a weekly feeding of a weak fertilizer (ie 1/4 tsp per gallon of water).  Remember weekly weakly.

Be sure to discard the old potting mix as there may be critters hiding there that may reinfect your plant.  You can see that another problem with summering the plant out is to pick up critters that like to live in the potting mix and take an occassional snack on plant leaves and roots.
