We have talked about the affect that the longer daylight days have on your indoor tropical plants' growth..
With the milder temperatures and increased humidity that accompany Spring, how much and how often you water your plants will change.
We are experiencing more days of dampness right now because of quickly melting snow and more rain. Even if you have a well-sealed building, which most aren't, some of that outdoor humidity is making its way indoors. As well, you are not running the furnace as high or as much because of the milder outdoor temperatures. This has the effect of increasing your indoor humidity levels.

With increased humidity, your indoor tropical plants are not giving off as much moisture through transpiration.
The overall result is that your plants, right now, will not need as much water. Check your plants at least once a week and adjust water/feed as required.
