How often should I water String of Hearts, and what light does it need?
String of hearts drapes delicate silver-marbled heart leaves on trailing vines. Bright indirect light and letting the soil dry between waterings keeps it thriving. Water it every 7–10 days while it is growing and every 14–21 days in winter, always checking the soil first. Give it bright, indirect light. It is non-toxic to cats and dogs — more detail below.

The short version
The one-sentence rule
Water when the soil dries out and the heart-shaped leaves feel softer. The delicate vines look fragile but are surprisingly tough.
Light, made concrete
What bright, indirect light actually means
Bright, indirect light — right beside an east or north window, or a little back from a sunny one, with no direct rays touching the leaves.
Pet safety
Is String of Hearts toxic to cats or dogs?
No — Not listed as toxic to cats and dogs. It is not considered toxic to pets, but any plant can upset a sensitive stomach, so it is still not a salad bar.
