Hi, I planted my yarrow last summer in zone 3 (Calgary, AB). It seemed to be doing fine, and it popped up this spring, but then it stopped growing and the leaves started dying before it got very high. They just kind of turned brown and wilted away. Any idea what's causing this? I see no sign of bugs.
