How to Grow and Care for String of Frogs

The String of Frogs, or Ficus pumila ‘Quercifolia’, is a trailing plant that has captured the attention of houseplant enthusiasts. Its common name derives from the unique shape of its small leaves, which are lobed like miniature oak leaves, creating the impression of tiny frogs climbing its delicate vines. This plant is a cultivated variety of the creeping fig, originating from East Asia. Its fine texture and cascading growth make it a popular choice for hanging baskets, terrariums, or as a spiller in mixed containers.

String of Frogs Care Guide

Light

This plant performs best in medium to bright, indirect sunlight. An ideal placement is near an east or west-facing window, but direct, intense sun should be avoided as it can scorch the foliage. While the plant tolerates lower light, its growth may become slower and less dense.

Soil

String of Frogs requires a potting mix that is well-draining yet rich in organic matter. A standard peat-based potting mix amended with perlite or orchid bark works well to improve aeration and prevent the soil from becoming waterlogged. Good drainage is important, as the plant’s fine roots are susceptible to rot if they sit in overly wet conditions.

Water

Consistent watering is needed to keep this plant thriving, as it prefers evenly moist soil. The String of Frogs is not particularly drought-tolerant and should not be allowed to dry out completely. Check the soil every few days and water thoroughly when the top 10 to 25 percent of the potting mix feels dry.

Temperature and Humidity

As a plant of tropical origin, the String of Frogs flourishes in warm and humid conditions. It is comfortable in average household temperatures but should be kept in environments above 55°F. The plant has a strong preference for above-average humidity, so in drier homes you may need to mist it daily, place it on a pebble tray, or use a humidifier.

Fertilizer

During the spring and summer growing season, feed the plant every four to six weeks. Use a balanced, all-purpose liquid fertilizer diluted to half-strength. It is not necessary to fertilize during the fall and winter when the plant’s growth naturally slows.

Propagating String of Frogs

This plant is easily propagated through stem cuttings. Using clean scissors, take a cutting several inches long that includes a few leaves and several leaf nodes (the small bumps on the stem where leaves emerge).

You have two primary options for rooting them. For water propagation, place the cuttings in a jar of water, ensuring the nodes are submerged while the leaves remain above the water. Place the jar in bright, indirect light, change the water every few days, and transfer to soil once roots form.

Alternatively, you can root cuttings directly in soil. Dip the cut end in rooting hormone (optional) and insert it into a pot with moist, well-draining potting mix, making sure at least one node is buried. Covering the pot with a clear plastic bag creates a humid micro-environment to help it establish.

Solving Common Problems

Even with attentive care, you might encounter some common issues.

• Crispy, browning leaf edges or leaves dropping from the vine are often indicators of insufficient humidity or inconsistent watering. The plant’s leaves will show stress if the air is too dry or if the soil becomes bone-dry.
• Yellowing leaves are a frequent sign of overwatering. If you notice the foliage turning yellow, check the soil moisture and allow it to dry out more between waterings. Ensure the pot has adequate drainage to prevent root rot.
• Leggy growth, characterized by long, bare stems with sparse leaves, is a direct result of inadequate light. To fix this, move the plant to a brighter location and prune the leggy stems back to encourage fuller growth.
• Pests like spider mites can be an issue. Inspect the undersides of leaves for fine webbing and treat any infestation with an insecticidal soap.

Pruning and Shaping

Pruning is a simple maintenance task that helps keep your String of Frogs looking full and lush. The primary purpose of trimming this plant is to encourage bushier growth and manage its trailing habit, as vines can become long and sparse without it.

Using clean scissors, you can trim back any vines that have become too long, leggy, or bare. It is best to make your cuts just above a leaf node, as this is where new growth will emerge. These trimmings can also be used for propagation.

You can prune your String of Frogs at any time of year, but light trimming is most effective during the growing season in spring and summer. Regular, light pruning is more beneficial than infrequent, heavy cutting for maintaining the desired shape.
