Watering at a glance

Base rhythm	When soil is fully dry, roughly every 10-14 days 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 10-14 days.
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 Fishhooks

Curio radicans 'Fishhook' · also called Fishhook Senecio · houseplant

String of Fishhooks is a trailing succulent, Curio radicans, with curved blue-green leaves shaped like tiny hooks along long, fast-growing stems. Tougher and more forgiving than string of pearls, it stores water in its leaves and produces small white, cinnamon-scented flowers. Give it bright light, gritty soil, and infrequent deep watering.

Ideal humidity: 30-50%

Watch for — Shrivelled hooks: Indicates underwatering. A deep soak usually re-plumps the leaves; check that the mix had dried fully first.

The watering schedule, season by season

String of Fishhooks 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 fishhooks is when soil is fully dry, roughly every 10-14 days 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 10-14 days.
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.

Drought-tolerant; water deeply then let the mix dry out completely. The fleshy hooks shrivel when very thirsty. Reduce to about monthly in winter to avoid rot.

How to tell string of fishhooks needs water

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

Overwatering vs underwatering string of fishhooks

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