Plant of the Week: Hydrangeas

Everyone’s favorite show stopper! Their massive flower clusters come in a variety of eye-catching colors like pink, blue, purple, red and white. Primarily shade loving, these deciduous shrubs add color, beauty and interest to wooded areas and shady garden beds.

Heights vary with dwarf varieties averaging 3’-4’ and full-sized varieties reaching between 8’ and 10’. Hydrangea Petiolaris is a climbing hydrangea that can reach more than 30’. 

Care

Most hydrangeas prefer morning sun and afternoon shade, or filter/dappled light throughout the day. However, some varieties, like the Limelight, prefer full sun.

They do best in moist, well-draining soil with a pH between 5.5 and 6.5. Some varieties, like Nikko Blue, will bloom blue in acidic soils and pink in alkaline soils.

Pruning hydrangeas depends on when they bloom. Hydrangeas that begin to bloom in spring should be pruned immediately after blooming and hydrangeas that begin to bloom in summer should be pruned during winter while the shrub is dormant.

Fertilize Hydrangeas beginning in spring with an acidic fertilizer, like HollyTone, or a fertilizer for blooming shrubs, like Dr Earth Total Advantage

Spray with a deer repellant, like Liquid Fence, to keep away hungry deer.
