Sudden Death of Established Rugosa Hedge: Diagnostic Checklist

Sudden Death of Established Rugosa Hedge: Diagnostic Checklist

10-year-old Rugosa hedge dying suddenly in Westchester County requires investigation:

• Leaf color/twist? (Herbicide drift).
• Black canes? (Waterlogged root rot).
• Recent sprays? (Rugosas hate chemicals).
• Fertilizer/chemicals at base? (Extreme sensitivity).
• Rose canker? (Growths on canes).
• Root knots? (Black nodes).
• Neighbor spraying?

Action

Dig up a plant; take to Dept. of Agriculture. Leaves hold the key clue.
