Care Guidelines

Now that you’re acquainted with the String of Frogs, let’s explore how to care for this charming houseplant.


String of Frogs thrives in partially diffused light. Prolonged exposure to direct sunlight can lead to leaf scorching and necrosis. Outdoors, it fares well under the canopy of trees, where it receives filtered light. Indoors, place it near east or north-facing windowsills or provide artificial grow lights to ensure it receives adequate light without becoming deficient.


Maintaining an optimal temperature range of 20 to 30 degrees Celsius is crucial for the well-being of your String of Frogs. As a tropical plant, it can tolerate temperatures as low as 10 degrees Celsius and as high as 35 degrees Celsius. Ensuring a cool, humid environment within this temperature range is key to its success.


This plant thrives in well-draining, loamy or sandy loamy soil with a neutral pH. Due to its delicate roots, it’s essential to avoid soil that retains excess moisture, as this can lead to root rot. Enhance the soil’s drainage by incorporating materials such as perlite, pumice, sphagnum moss, small pebbles, and organic matter.


String of Frogs requires moderate watering. Allow the top 2 inches of soil to dry out before watering, which typically translates to once a week. Adjust the watering frequency in response to extreme temperature fluctuations, increasing it during hot spells and reducing it to once every two weeks during winter. Always ensure that the soil remains moist but not waterlogged.

Pro Tip: Test soil moisture by inserting a finger 2 cm into the soil. If the soil adheres to your finger, it doesn’t require watering. If your finger emerges clean, it’s time to water the plant, taking care to water at the root level without putting pressure on the stem.


String of Frogs thrives in a cool, humid environment, with an ideal humidity range of 60% to 80%. This elevated humidity contributes to its glossy leaf appearance. You can maintain humidity by misting the plant, using a humidifier, or employing the pebble tray method, especially in areas with lower humidity levels.


While not mandatory, fertilizing your plant once a month can promote healthy growth. Use a diluted liquid fertilizer, preferably during the summer and spring months when the plant experiences faster growth.

Potting and Repotting

When potting your String of Frogs, select a pot size that accommodates its growth and the available space in your environment. Opt for earthen pots with drainage holes to facilitate proper drainage. Add a well-draining soil mix to the pot, insert the rooted plant, and maintain soil moisture in a shaded area.

Repotting is typically necessary every 2 to 3 years as soil nutrients become depleted. Select a larger pot during repotting, ensuring the new soil is nutrient-rich.

Training and Pruning

Prune diseased or dead twigs as needed. Training can be conducted annually or semi-annually to achieve the desired size and shape. The plant’s growth rate accelerates after training and pruning.
