Transplant Shock in Weeping Norway Spruce and Branch Viability Test for Tiger Eye Sumac

Transplant Shock in Weeping Norway Spruce and Branch Viability Test for Tiger Eye Sumac

Weeping Norway spruce bought in poor condition (bare side, brown needles). After planting, wind storm caused needle drop. Tiger eye sumac (3 yrs, 4 ft, 3 branches) has one branch not sprouting.

Spruce: Transplant Shock

• Container/B&B plants suffer root disturbance.
• Needle drop after wind = stress response.
• Water thoroughly at planting, then wait 3–4 days. Overwatering causes anaerobic soil.
• If branches become brittle and needles drop extensively → may not recover.

Sumac: Branch Viability Test

1. Scratch bark with thumbnail on suspect branch (2–3 spots).
2. Green under bark = alive. Brown = dead.
3. Flexible twig = good sign.

Action

• Spruce: Patience, minimal watering, monitor.
• Sumac: If branch is dead, prune it out next spring. If alive, it may just be delayed.

Both plants need time to reveal their fate.
