Description
Smooth hydrangeas (Hydrangea arborescens) are adored for their huge globe-like blooms that look amazing in hedges and privacy fences. These blooms appear mid-summer and look fabulous in cut-flower arrangements. This North American native blooms on new wood, which means it will create its flower buds only after it starts growing this spring; no flower buds are present on this type in winter.

How to Grow
Light: Part-sun (4-6 hours sun). It especially enjoys morning sun and afternoon shade.
Water: Water to keep soil moist, but not wet. Intolerant of drought, so don't allow the soil to dry out.
Spacing: 4-6 feet
Fertilizing: It is generally unnecessary, but you can fertilize once in spring if soils are deficient or growth is slow.
Winterizing: Remove and destroy any fallen foliage that was infected by powdery mildew. Spread a layer of mulch around the plant for added protection.
Maintenance & pruning: This variety blooms on new wood. In late winter or early spring, cut stems back by about one-third their total height, which builds a strong woody base while also encouraging abundant new growth for lots of flowers and a lush, full look.
Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:
