Transplanted Fir Mortality: Proper Technique for Future Success

2-year firs transplanted, now completely brown/red. Mulch, watered every other day, compost added. Owner asks if dead and if watering helps.

Conifers don't resprout from brown crowns. Every-other-day watering likely drowned roots (same symptoms as drought).

Timing: fall (≥6 wks before freeze) or spring (≤4 wks after deciduous leaf-out).
Root ball: 9–12″ width/inch caliper, 6″ depth/inch.
Protect roots: moist burlap, minimize exposure.
Hole: 2× ball, backfill topsoil, mulch 3″.

Water weekly 1″, not daily. Conifers need oxygen at roots.
