About the Mountain Hydrangea
Gorgeous shrubs that form full, lacey-centered blooms add fantastic shades of pink, blue, or purple to the summer landscape over big, waxy, medium to dark green leaves. Blue and pink flowering types colors can be changed by adjusting soil pH, (see care instructions). Mountain hydrangeas are known for their increased winter hardiness, compact growth habits and the capacity to repeat bloom, producing buds and flowers on old and new wood. Their blooms make stunning additions to fresh and dried arrangements. They grow best in protected, partial shade near homes, in a landscape border, as a specimen, or as a hedge.

Care Notes
Plant in well-drained to moist, amended soil. Water well after planting; maintain 1” of water once a week the first year. Prune down to uppermost growth in spring. Remove dead, winter damaged stems and silver, older wood at this time. Deadhead in summer through fall. Feed early spring and mid-summer with a slow release fertilizer. For blue flowers use Aluminum Sulfate or Garden Sulfur; for pink apply Garden Lime. Use Triple Phosphate to help force blooms. Follow label instructions. Mulch 2″ to suppress weeds, retain moisture and protect against extremes of soil temperature. Benefits from winter protection.
