Tubers on string of hearts

string of hearts with tubers

What's Happening

Aerial tubers are the primary survival and propagation mechanism for Ceropegia woodii. These modified stems store water and carbohydrates, allowing rapid rooting when they contact soil. Tubers form at leaf nodes during active growth as insurance against drought or stem damage.

How to Fix It

  1. 1

    Locate aerial tubers—they appear as small white/pink swellings at nodes along stems

  2. 2

    Tubers indicate propagation-readiness: nodes with tubers root 3x faster than without

  3. 3

    For maximum tuber formation: maintain 40-60% humidity and fertilize with diluted balanced fertilizer (10-10-10 at 1/4 strength) monthly during spring-summer

  4. 4

    Tuber viability test: firm and opaque tubers are healthy; shriveled or translucent tubers indicate dehydration or damage

  5. 5

    When propagating, prioritize nodes with largest, firmest tubers for highest success rate

How to Prevent It

Encourage tuber development by providing 12-16 hours bright indirect light during growing season (spring-summer). Avoid prolonged underwatering that forces tuber depletion.
