I had purchased a Hilda Niblett Azalea in Spring. I had planted in a larger pot because I was told it will not survive our Wisconsin winters. It is growing beautifully in the pot and I would like to know how I should overwinter it. Can it be put in a garage over the winter or should I bring it indoors. I believe that I am in zone 4 or 5 (Wisconsin 53207). Wish I could have planted in the ground, have a perfect spot for it that gets the perfect amount needed , but I do not want to lose it to our winters if possible.
