In spring, the light in front of a south- or west-facing window becomes more intense and abundant daily and also starts to extend beyond what our houseplants, which are tropical plants accustomed to 12 hours of daily sunshine, receive in their native lands. And behind glass, there is not much air circulation. Thus, heat can easily increase to a point where the plants become damaged.
In this season, therefore, it is wise to keep an eye on your houseplants, either moving them back from south- or west-facing windows or placing them in rooms where the light is less intense. Start when you notice any signs of distress, like foliage wilting, curling or turning pale on one side only, that closest to the window.
