Answer: Based on your description and now knowing that you are gardening in New Jersey, it is quite possible that your azaleas are a deciduous variety and have naturally turned their fall color and dropped their foliage for the winter. If this is the case, all you need to do is make sure they have several inches of organic mulch over the root area. Pine bark or pine fines or similar material should be in a flat layer about two to three inches thick; spread it out beneath the plants and do not allow it to touch the stem/trunk. Do not fertilize them until spring. Good luck with your azaleas!
