Yucca Root Rot in Hydroculture: Trunk Firmness Test, Dry-Out Protocol

Hydroculture Risk

Constant moisture + organic media = rot city for desert-adapted Yuccas. Water meter "dry" may not reflect root zone.

Trunk Test

Press trunk at soil line:

• Soft: Dead — replace.
• Firm: Proceed with dry-out.

Dry-Out Protocol

1. Remove from hydroculture; wash all media off roots.
2. Trim all black/mushy roots.
3. Pot in gritty cactus mix (terra cotta).
4. No water 2 weeks.
5. Then water only when dry 2 inches deep.
6. Superthrive monthly ×3.

Future Care

Yuccas in Singapore humidity need exceptional drainage and bright light. Hydroculture unsuitable.
