The Philodendron may be in some shock from broken roots and re-potting.
What size pot was it is in before? What size pot is it in now?
You only want to go up an inch larger with good draining soil, or the soil can stay too wet (too much soil) smothering the roots, thus causing rot.

Try cutting off some of the top growth to compensate for the loss of roots. These cuttings can easily be put in the pot with the adult plant to help fill it out quicker or put in a smaller pot to root then put in the big pot. There aren't enough roots to take care of the growth it has so it is dropping leaves. I'd also bake sure the pot is not too large and the soil does not stay too moist. Also put it in less light for about a week or so to adjust to the chopping. GL

Thanks for the suggestions, there isn't a lot of "top growth" it was pretty much stretching out in just one direction. The pot it was in was very small, and I think the one we're in now is about double it's size. I'll trim back the two "shoots", hold off on watering for a week or so and see if we have any luck. Thank you!

We have a huge philodendrun at work and I've been taking care of this plant for about 2 years. I've noticed recently that the leaves are wilting. I watered it about 6 weeks ago, with Miracle Grow and gave it a "haircut". At first I thought it wasn't getting enough sunlight. That was one week ago and I noticed yesterday the leaves are wilting more. So, I closed the blinds in just a little. I'm hoping that will solve the problem. Can you shed some insight on this?
Thanks.
