Multiple Roses Dying One Cane at a Time in Tacoma, WA

Many roses around house: one stem drops leaves, dies, then another. Tacoma, WA (Zone 8).

Systemic Cause Affecting All Roses

Since many roses affected, it's something applied to all:

• Herbicide drift (lawn weed killer) → curls leaves, kills canes, then plant. Even "no wind" drifts.
• Chemical fertilizer/foliar feed in heat → root burn.
• Cane borer (enters pruning cuts) → hollows cane → leaves die.
• Soil issue if all newly planted.
