If you think moving to a new home means trauma for you, consider what it means for your houseplants.
Typical is the Denverite who moved to a home with vaulted ceilings and tall southeast-facing windows. Come mid-winter, the room was warm and flooded with sunlight. What more could a houseplant ask?
A lot more if those particular houseplants do not like sunlight. When you move your houseplants, consider the microclimate to which they have been accustomed, as well as that to which they will move. Plants that thrived in a cool room "back home" will need similar circumstances in their new surroundings. While people can adapt to the changes a move will bring, houseplants can't.
A lot of factors contribute to the health of indoor plants, including humidity, duration and intensity of sun exposure. Even within a room, these factors can vary. Some plants are temperature-sensitive, requiring steady warmth or coolness. Others may require a drop in nighttime temperatures. Still others may require a winter rest, with a constant thermal environment of 45 to 50 degrees from late fall through early spring. Your assignment is to know the conditions under which your plants will thrive.
When you buy plants, ask about their needs. Be realistic. If you can't provide for those needs, look for another type of houseplant that fits your situation. Here is a list of houseplants and their preferred microclimates to get you started:
Warm and sunny (direct sunlight, near a south, east, or west-facing window--60-70 degrees all year.
Warm, filtered sun (same exposure and temperature; light filtered by a leafy tree or translucent curtain)
Warm, shady (same temperature but no direct sun exposure; near north-facing window or to the side of a sunny window)
Cool, sunny (50-60 degrees all year, direct sun)
Cool, filtered sun (50-60 degrees, bright but filtered light)
