I forgot to ask how large is the container you repotted it to? If you plant something with little root system into a large pot, the plant will concentrate on filling the pot with roots before new branch/leaf growth. I always go for a smaller size pot rather than larger.
First though, I need to state that I'm not an expert, far from it in fact! Regarding the frequency of watering; if the soil stays extremely wet it can cause issues with the plants roots and you might end up with root rot; I always lean towards the dry side myself. At this time of year I'd only water lightly every few weeks, letting the tree get established in it's new container but that's just my method. My conditions (even indoors) are probably greatly different from yours. For instance, we still have our air conditioning running, while I'm sure you have the heat going in N.Y. I've heard folks in the north talk about issues they encounter with their plants in winter due to dry air with heating their homes so hopefully others will chime in with some tips.
