Adam's Needle Yucca Yellowing: Water Investigation

Likely Cause: Excess Moisture

One yucca yellowing while neighbor thrives suggests localized overwatering. Check:

• Sprinkler hitting one more than other.
• Low spot collecting water.
• Soil drainage difference.
• Recent heavy rain in your area.

Action

Divert water from affected plant. Yuccas need sharp drainage and dry periods. No fertilizer until recovered.
