Half My Hedge Turned Brown Overnight—and the Cause Was Right Under My Feet

I walked out one June morning and half my boxwood hedge looked like it had been torched overnight.

The left side was green and glossy, exactly as it had been the day before. The right side—twelve feet of it—had turned a dull, papery brown. Not a gradual fade. Not a few branches here and there. A hard line, as if someone had drawn it with a ruler.

I’d watered the whole hedge the same way. Same sun, same soil, same plants from the same nursery eighteen months earlier. There’d been no frost, no dogs, no chemical spills I could remember.

But something had clearly changed, and it had changed fast.

You expect a plant to decline evenly if it’s sick—bug damage on new growth, fungus creeping from one end, maybe drought stress hitting the sunniest spots first. You don’t expect a perfectly vertical split, green on one side and dead on the other, like two different time zones.

I pressed my thumb into the brown foliage. Brittle. Completely dry.

So I grabbed a spade and started digging where the green stopped and the brown began.
