Welcome to the Jungle!!!!
Generally in our zones when you and I bring our plants in for the winter you will see notice in Jan, Feb, March that your plants are screaming(like little kids)that they want to go outside to the brighter sun and natural warmth.
In this three month span my plants will start to show yellow/brown leaves and a general decline in the vigorous healthy growth they had outside. Some of them will lose all their leaves, however they all will grow back.
It is human nature to overwater you plant once it shows any kind of problem.
The previous posts pretty much sum it up.
