String of Pearls Care
The String of Pearls succulent is easy to care for, but it is important to take the right care of your string of Pearls plant to keep it healthy.

String of Pearls Plant Care
String of Pearls Watering Needs
Succulents are fond of decent drainage and any flower will end up dying if it doesn't get enough water. When it comes to watering your string of pearls, it's important to strike the right balance. This hanging succulent is native to arid regions, so it prefers drier conditions. However, String of Pearls does not require too much watering. It cannot survive for a longer period in soggy soils and thus avoiding overwatering works best for this plant.
To meet its watering needs, you'll want to follow a "soak and dry" method. Water these succulents thoroughly during the growing season and reduce watering when they go dormant in summer. Give your string of pearls a thorough watering, allowing the water to completely soak the soil. Make sure to let the soil dry out before watering again. This usually translates to watering every 2-3 weeks, but it can vary depending on factors like temperature and humidity. Remember, it's better to underwater than to overwater your pearl plants.
When watering, make sure to pour the water directly onto the soil and avoid getting the leaves wet. Excess moisture on the string of pearl leaves can lead to rot or damage their shallow root systems. Additionally, using well-drained soil and a pot with ample drainage holes can help prevent water from sitting in the roots.
Observing your string of pearls closely will also help you determine its watering needs. If its leaves start to look shriveled or wrinkled, it's a sign that your pearl plant is thirsty. On the other hand, if the leaves appear plump and healthy, you can hold off on watering for a bit longer. It's all about finding the right balance and giving your string of pearls the care, it needs to thrive.
String of Pearls Light Requirements
When it comes to a string of pearls' light requirements, it thrives in bright, indirect light. Place your pearl plant near a window where it can receive bright, filtered sunlight for at least 4-6 hours each day. This string of pearls plant also thrives in full sun, making it one of the best choices for container gardening. However, be cautious of exposing it to direct sun for extended periods, as it can scorch the delicate leaves. If your hanging string of pearl plants starts to stretch or become leggy, it might be an indication that it needs more light.
If you don't have a spot with bright indirect light, you can also use artificial grow lights to provide the necessary bright light for your string of pearls. LED grow lights are a great option as they emit the right spectrum of light for your succulent plant growth. Place the lights about 6-12 inches above these delicate pearl plants and keep them on for around 12-14 hours a day. This will help mimic natural sunlight and keep your string of pearls happy.
Remember, finding the perfect balance of light is key. Too little light can result in leggy growth and pale leaves, while too much direct sunlight can cause leaf burn. Keep an eye on your string plants and adjust their lighting conditions as needed to ensure they thrive and maintain their beautiful appearance.
String of Pearls Soil & Fertilizer Needs
For the soil, you'll want to use well-draining sandy soil that allows excess water to flow through easily. Use a well-drained specialty soil mix, as this type of potting soil mix has been precisely developed to imitate well-drained desert soils. The commercial succulent mix is affordable and accessible online. Here at Planet Desert, we have a specialty-formulated succulent potting mix that contains 5 natural substrates and organic mycorrhizae to promote the development of a shallow root system that helps your succulent to thrive. An okay alternative is to make your own soil at home, that is if you don't mind getting a bit of dirt on your hands and you are okay with a mediocre succulent soil mix. If so, simply combine healthy natural garden soil with equal parts of sharp sand, coarse sand, or perlite.
As for fertilizing, a string of pearls doesn't require heavy feeding. During the growing season, which is typically spring, you can use a natural NPK fertilizer once a year with an equal mix of 5-10-5. This ensures that you don't overfeed your string of pearl hanging plant, which can lead to salt buildup and other issues. Reduce feeding during dormancy.
Remember, it's always better to under-fertilize than to over-fertilize your string of pearls. These string plants are adapted to survive in nutrient-poor environments, so they don't need a lot of extra nutrients. With the right soil and a light feeding schedule, your string of pearls will be happy and healthy.

2- Do not let the soil lose its moisture. Place a plastic bag around the pot to keep it moist.
