Gray Water Irrigation May Harm Shrubs Due to Phosphate Buildup

Household Wash Water Can Be Toxic

Watering your Golden Box Honeysuckle with gray (wash) water likely introduced phosphates and other chemicals that accumulated to toxic levels in the soil, causing the branch-by-branch dieback.

Switch Water Sources

• Use municipal tap water or collected rainwater.
• Flush the root zone with several deep waterings to leach excess salts.

Gray water is fine for lawns or ornamental beds with high salt tolerance, but sensitive shrubs often decline.
