About Ruby Necklace
Othonna capensis · also called Ruby Necklace, String of Rubies · houseplant
Ruby Necklace (Othonna capensis, syn. Crassothonna capensis) is a trailing South African succulent with bean-shaped leaves on purple stems that flush ruby-red in bright light, plus tiny yellow daisy flowers. Give it bright light, gritty fast-draining soil and sparing water. It is not ASPCA-listed; treat as mildly toxic and verify with a vet.
Ideal humidity: Average to low (around 30-50 percent)
Watch for — Mushy, translucent stems / root rot: The most common problem, caused by overwatering or soil that holds moisture. Let the mix dry out fully between waterings, use a gritty fast-draining medium and a pot with drainage holes, and cut back hard on water in winter.
The watering schedule, season by season
Ruby Necklace 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 ruby necklace is roughly every 1-3 weeks; let the soil dry out completely between waterings, 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 1-3 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.
Treat it as a true succulent and water with the soak-and-dry method: drench thoroughly, let all excess drain, then wait until the mix is bone dry before watering again. Water more in spring and summer growth, much less in winter. The leaves plump up when hydrated and soften slightly when thirsty. Overwatering is the number-one killer, causing mushy, translucent stems and root rot.

How to tell ruby necklace needs water
A calendar is the worst way to water ruby necklace. 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 ruby necklace for a day is almost always safer than over-watering it.
Overwatering vs underwatering ruby necklace
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For ruby necklace 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 ruby necklace. 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 ruby necklace; 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 ruby necklace, 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 ruby necklace.
