There are several things to be aware of for your tropical plants spending the winter indoors. First is good light.

I can provide most of my plants with very good light since I have both a sunroom and a greenhouse. However, for most folks getting adequate light to plants in the house during winter is difficult. Less light and generally dry conditions from our heating systems place stress on these plants.

Depending on the plant and its size, artificial light can sometimes be provided to help indoor plants by using florescent or other light fixtures. This often takes quite a bit of room and is something that many people cannot or do not want to do. Rotating plants to a bright window can help including in the garage if it is warm enough.

For most plants, too little water is better than too much.

Weakened plants under stress are more susceptible to problems. The three most common pests I confront inside are fungus gnats, whiteflies, and
