Troubleshooting
String of Frogs problems — and how to fix them
String of Frogs (Ficus pumila 'Quercifolia') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown, crispy leaf tips and edges
The number-one issue: air that is too dry. Raise humidity above 50% with a humidifier, pebble tray or enclosed terrarium, and don't let the soil fully dry out.
Sudden leaf drop
Triggered by shock — cold drafts, hot air from heating/AC vents, or inconsistent watering. Keep it away from vents and doors and maintain steady moisture and temperature.
Wilting or shrivelling from underwatering
This cultivar is not drought-tolerant; if the whole plant droops and the mix is bone dry, water thoroughly and consider checking it more often. Persistent dryness kills the fine foliage fast.
Yellowing leaves and mushy stems from overwatering
Soggy, poorly drained soil causes root rot. Use a well-draining mix, empty saucers, and let the top of the soil dry slightly between waterings.
Sap-sucking pests (spider mites, scale, mealybugs, aphids, thrips)
Most likely on stressed or low-humidity indoor plants. Inspect regularly; treat with a firm rinse, insecticidal soap or horticultural oil and isolate affected plants.
Leggy, sparse growth
Caused by too little light or over-fertilising. Move to brighter indirect light, feed only in the growing season at reduced strength, and pinch back stems to encourage bushier growth.
