Watering at a glance

Base rhythm	When the soil is fully dry, roughly every 2-3 weeks in growth
Spring / summer	Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 2-3 weeks.
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 Tears

Curio herreianus · also called string of tears, string of watermelons · houseplant

String of tears is a trailing succulent (formerly Senecio herreianus) whose plump, tear- or watermelon-shaped beads are striped with darker translucent lines that act as light windows. Closely related to string of pearls, it wants bright light, very sparing water, and gritty soil. It cascades attractively from a hanging pot but resents wet feet.

Ideal humidity: 30-50%

Watch for — Shrivelled, deflated beads: Usually underwatering or, paradoxically, root rot from overwatering. Check the roots: firm roots mean give water; mushy roots mean dry out and re-root healthy stems.

The watering schedule, season by season

String of Tears 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 tears is when the soil is fully dry, roughly every 2-3 weeks in growth, 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 every 2-3 weeks.
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.

Water deeply then allow the mix to dry out completely. The beads store water, so underwatering is far safer than over. In winter water only enough to keep beads from shrivelling, perhaps monthly.

How to tell string of tears needs water

A calendar is the worst way to water string of tears. 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 tears for a day is almost always safer than over-watering it.

Overwatering vs underwatering string of tears

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

String of Tears watering — frequently asked questions

How often should I water string of tears?

Water string of tears when the soil is fully dry, roughly every 2-3 weeks in growth.

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 single most reliable test for string of tears is the first signal on that list — checking the soil or the plant directly always beats watering by the calendar.
