Watering at a glance

Base rhythm	When the top 1-2 cm (top inch) of soil is dry, often 1-2x per week in spring/summer
Spring / summer	Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around when the soil tells you it is time.
Autumn	Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
Winter	Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.
Light	Bright indirect light (just back from a sunny window)

About String of Frogs

Ficus pumila 'Quercifolia' · also called String of Frogs, Miniature Oakleaf Fig · houseplant

String of Frogs is a dwarf cultivar of creeping fig (Ficus pumila) with tiny, oak-leaf-shaped foliage on dainty trailing stems, prized for hanging baskets and terrariums. It wants bright indirect light, steadily moist soil and humidity above 50 percent. As a true Ficus, it is toxic to cats and dogs.

Ideal humidity: 50% or higher; thrives at 60-80%

Watch for — 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.

The watering schedule, season by season

String of Frogs stores water in its thick leaves and stems, so when in doubt, wait — it survives drought far better than soggy soil. The base rhythm for string of frogs is when the top 1-2 cm (top inch) of soil is dry, often 1-2x per week in spring/summer, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around when the soil tells you it is time.
Autumn (slowing down): Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
Winter (rest / dormancy): Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.

Keep the mix lightly and evenly moist; this cultivar is not drought-tolerant and the thin leaves crisp quickly if it dries out, yet soggy roots cause rot. Water thoroughly until it drains, then let the surface dry slightly. Cut back in autumn and winter as growth slows.

How to tell string of frogs needs water

A calendar is the worst way to water string of frogs. Check the plant and the soil instead — for this species, look for these signals in order:

The lower or oldest leaves feel slightly soft or look a touch wrinkled.
The pot is noticeably light when lifted.
Soil is dry several centimetres down, not just at the surface.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering string of frogs for a day is almost always safer than over-watering it.

Overwatering vs underwatering string of frogs

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For string of frogs specifically:

Signs you are overwatering

Leaves turn translucent, yellow, soft and mushy — classic overwatering.
Lower stem darkens or goes squishy at soil level.
Whole rosettes or sections drop at the lightest touch.

Signs you are underwatering

Leaves pucker, wrinkle or curl inward — a harmless thirst signal that reverses fast after a soak.
Older leaves dry crisp from the tips first.

Overwatering is the number-one killer of string of frogs. The thick leaves are a water tank — a slightly thirsty plant recovers in a day; a waterlogged one rots from the roots up.

Water quality notes

Tap water is generally fine for string of frogs; the soak-and-dry rhythm matters far more than water type.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For string of frogs, the levers that matter most are:

A gritty, free-draining mix is essential — ordinary potting soil holds too much water for this plant.
Terracotta dries faster and is more forgiving than plastic or glazed ceramic.
More light and warmth speed drying, so the interval shortens in peak summer — always check, never assume.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of string of frogs.
