String of Pearls - 4"
Either grown indoors or outdoors, String of Pearls plants need to be placed in a spot where it can get at least 6 to 8 hours of bright, indirect sunlight per day. But again, you have to find a partially shaded spot to grow this plant outdoors.
If kept indoors, place your String of Pearls in a spot where it can receive plenty of strong natural light, like near an east-facing window. Growing it near a South or West-facing window will also do, as long as you place the plant about 5 to 10-inches away from the window, especially if you live in a hot, desert-like area to prevent it from getting sunburnt. In darker, cooler months, consider moving them to a brighter spot or closer to the window to make sure they get all the light they need per day.
String of Pearls are very sensitive to overwatering, so make sure that you give them just enough water. Recommended amount is once every two weeks. One tip to make sure you don't overwater your plant is to check if the soil is half an inch (1.2cm) dry before the next water. During winter time, cut back watering to once per month.
