I planted 5 Monet Weigela last spring. They did OK last summer, but have not started to show any life yet (mid April). I am in Colorado, zone 4 or 5. Is it too early to be worried, or do you think they are dead?
It is a bit too early to be worried; weigela does not emerge in early spring. Mine did fine even through those awful polar vortex winters of several years ago.
