Winter Burn: Dwarf Alberta Spruce #207699

My dwarf alberta spruce shrubs were hit hard by the long periods of snow and ice last winter. This Spring, they were totally brown. A friend advised to treat the shrubs with Ironite. Sure enough, they started to green up and look 85% better now. I've also applied Miracle Grow about once a month over the summer to feed them. Do you think that the remaining dead patches will fill in and heal?

They may. The DAS (Dearf Alberta Spruce) took a severe hit this last winter surprising many of us in the nursery industry. There are other garden pests that affect DAS as well though. Try spraying your bush with a vigorous spray of water twice over a two week period. The damage might be from spider mites after the winter damage. Don't prune until you have a good assessment of the damage and the plants resilience to it. In fact with DwarfAlberta Spruce you shouldn't prune at all until damage control is finished.
