Why Green Giant Arborvitae Die: The Wire Basket Mistake

The Fatal Error: Leaving the Wire Cage On

A homeowner planted 18 Green Giant arborvitae (8–10 ft) in November. One died by April; the rest show yellowing needles near the trunk. The landscaper left the metal wire basket around the root ball intact—and that's almost certainly why the tree died.

Why Wire Baskets Kill Trees

The wire cage prevents roots from expanding into the surrounding soil. They circle inside the basket, become girdled, and can't access water or nutrients. Even if the burlap rots, the wire persists for decades, effectively strangling the tree.

What to Do Now

• Confront the landscaper: this is a planting error, not a watering issue.
• For surviving trees, there's no fix—the damage is done at planting.
• Future plantings: always remove wire baskets, burlap, and twine before backfilling.

The landscaper's "1-month warranty unless on drip irrigation" is a red herring. Proper planting technique matters far more than irrigation method.
