Thuja Green Giant Top Wilting: New Growth Not Hardened Off

Why Green Giant Arborvitae Leaders Lean Over

Two-year-old, 9-ft Thuja ‘Green Giant’ tops are bending like wilt, but foliage is green and healthy. Other trees nearby are upright.

Diagnosis

Fast-growing conifers often produce tender, succulent new growth that hasn’t lignified (hardened) yet. The soft tips simply can’t support their own weight—especially after a flush triggered by rain or quick-release fertilizer (Miracle-Gro).

Corrections

Stop quick-release fertilizer. Use slow-release tree fertilizer in early spring only.
Water only during drought. Thujas hate wet feet.
Wait. Tips will stiffen in a few weeks and straighten naturally.

No disease or permanent damage—just adolescent growing pains.
