String of Rubies Care Tips

The string of rubies is an easy-to-grow succulent that produces delicate yellow flowers for most of the year when properly cared for. Here are some essential care tips for ensuring that your string of rubies thrives:

Light

Indoor Lighting: Place your string of rubies in a bright, sunny, south-facing window that receives at least six hours of direct sunlight each day. If you don’t have enough natural light, consider using strong grow lights to supplement.
Outdoor Lighting: When grown outdoors, string of rubies does best in full sun to partial shade conditions. Direct sunlight will cause the leaves to turn a vibrant ruby red, while low light conditions may result in greener leaves.

Soil

Well-Draining Soil: The string of rubies succulent thrives in well-draining, acidic soil with a pH between 6.0 and 6.5. You can use commercially available cactus and succulent soil mixes or create your own mixture with perlite, sand, and/or pumice for optimal drainage.

Water

Drought-Tolerant: Allow the soil to dry out completely between waterings to prevent root rot. String of rubies is considered drought-tolerant and does not require frequent watering.
Proper Drainage: Ensure that the pot has good drainage to prevent water from pooling at the bottom.

Temperature and Humidity

Warm Temperatures: String of rubies thrives in warm temperatures and should not be exposed to temperatures below 50 degrees Fahrenheit (10 degrees Celsius) for extended periods.
Household Conditions: When grown indoors, maintain typical household temperature and humidity levels for the best results.

Fertilizer

Low-Nitrogen Fertilizer: While string of rubies is not a heavy feeder, you can fertilize it a couple of times during the spring and summer months to support new growth. Opt for a fertilizer that is low in nitrogen for best results.
