• Bright, indirect light produces tight leaf spacing and strong silver marbling
• An east-facing window or a few feet back from a south or west window is ideal
• Gentle morning sun deepens the purple leaf undersides beautifully
• Too little light causes long, bare stretches of vine between leaves

• Water only when the soil is completely dry (typically every 2-3 weeks)
• Leaves that feel slightly soft or flat are your signal to water
• Water thoroughly, let it drain fully, and never leave the pot sitting in water
• Cut back significantly in winter when growth slows to a near stop

• Low to moderate humidity: 40-50% - average household air suits it perfectly
• Temperature range: 65-80°F (18-27°C) year round
• Keep above 60°F (15°C), as this plant has no cold tolerance
• Protect from cold drafts, open winter windows, and heating vents

• Use a cactus or succulent mix with extra perlite or coarse sand
• Always choose a pot with drainage holes, since the tubers rot in soggy soil
• Feed monthly in spring and summer with a balanced fertilizer at half strength
• Repot every 2-3 years in early spring, keeping it slightly snug in its pot

• Trim vines anywhere along the strand to encourage fuller growth at the top
• Press the small aerial tubers into soil to root brand new plants
• Stem cuttings root easily in water or laid flat on damp soil
• Separate tangled vines gently by hand, never by pulling, to protect the leaves

Wide spacing between leaves almost always means the plant needs more light. Move it closer to a bright window and new growth will come in tighter and more heavily marbled. You can also trim the leggy sections and tuck the cuttings back into the pot to fill it out.

Water only when the soil is completely dry, usually every 2 to 3 weeks. This plant stores water in its leaves and tubers, so underwatering is far safer than overwatering. Soft, flattened leaves are your reliable cue that it is thirsty.

Yellowing leaves usually point to overwatering or a pot without enough drainage. Let the soil dry out completely, check that water moves freely through the pot, and make sure the plant is getting bright light rather than deep shade.

Yes! String of Hearts (Ceropegia woodii) is non-toxic to cats and dogs, making it one of the very few trailing vines that pet-loving households can hang or shelve without worry. Cats do find the dangling strands fun to bat at, so a spot out of easy reach keeps the vines intact.

Those are aerial tubers, sometimes called beads, and they are the reason this plant earned the name Rosary Vine. They are a natural sign of a healthy plant and can be pressed into damp soil to grow entirely new String of Hearts.
