How to Grow
Light: Most varieties tolerate full sun in the North, but benefit from afternoon shade. They tolerate full sun only if grown with consistent moisture. In the South, plants require afternoon shade. Intolerant of drought, with foliage tending to decline considerably in dry conditions
Water : Water to keep soil moist, but not wet.
Spacing: 2-3 feet
Fertilizing: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15).
Winterizing: Remove any fallen foliage. The roots are shallow, so apply an extra 2-3" layer of mulch for insulation before winter.
Maintenance & pruning:Bloom on old wood, which means they have their flower buds for the following season all through winter, so they should not be cut back. Avoid pruning your mountain hydrangea except for dead wood in the spring.
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:
