Planting & Care

Where to Plant

  • Sunlight: This mountain hydrangea thrives with at least 4 to 6 hours of morning sun followed by dappled afternoon shade. While it can handle more sun in cooler climates, providing afternoon relief prevents the delicate, double lacecap blooms from wilting in the summer heat.
  • Soil: Aim for rich, well drained soil that stays consistently moist but never soggy. If you have heavy clay, mix in some organic compost to improve drainage, or plant in a slight mound to keep the roots from sitting in stagnant water.

Watering Requirements

During the first year, water your hydrangea deeply two to three times a week to help the root system reach deep into the soil. Once established, it is more drought tolerant than many Bigleaf varieties, but you should still provide supplemental water during dry spells to maintain the vibrant flower color and lush foliage. Inconsistent moisture often leads to scorched leaf edges and smaller flower clusters.

Pruning Tips

Because Tuff Stuff Ah-Ha® blooms on both old and new wood, you have a lot of flexibility, but the best time to prune is immediately after the first flush of flowers fades. Simply "deadhead" by cutting the spent stems back to the first set of large leaves to encourage a second wave of blooms later in the season. Avoid heavy pruning in late fall or early spring, as you might accidentally remove the flower buds already set for the coming year.

Fertilizer Needs

Apply a balanced, slow release fertilizer designed for woody shrubs in early spring just as new growth begins to emerge. Avoid high nitrogen fertilizers late in the summer, as this encourages soft, leafy growth that can be easily damaged by the first frost. If you want to influence the bloom color, use soil acidifiers for blue tones or garden lime for pinker hues.

Need a petite pop of color to polish up your undemanding landscaping plan? The answer is... always!

No matter how big or small your space might be, you'll find room for the outstanding flowers of the Proven Winners® ColorChoice® Tuff Stuff Ah-Ha® Hydrangea bush (Hydrangea serrata TUFF STUFF Ah Ha® 'SMNHSDD') will constantly show blooms from late spring into fall! This Mountain Hydrangea is a prolific producer of enormous, flat-topped blooms composed of many double florets. Just one lacecap cluster will nearly fill your hand and grace a bouquet!

These delicate double blooms look just like painted porcelain! Use them as spectacular cut flowers, or enjoy them in your garden setting as they fill with butterflies. Thick, bold foliage is dark green and features finely serrated edges. Its steady strength makes a marvelous contrast to the delicacy of the blooms. And you’ll enjoy wave after wave of bloom as these develop on both new and old wood! Even when not in bloom, you'll be delighted with these compact shrubs! Gain a brilliant fall color display when the leaves turn burgundy-red-purple in autumn.

Like other Mountain Hydrangeas, the color of the florets is determined by your soil pH. You can have bright pastel-pink, rich sky-blue, or any color on the spectrum between the two, depending on your soil. Change the pH to change the flower color. Hydrangea is also surprisingly versatile in many garden applications. You'll get charming season-long color, great form, and outstanding fall color. This high-impact small plant is a wonderful value! Even beginners will have success with this field-tested selection from Proven Winners®.

How To Use Tuff Stuff Ah-Ha® Hydrangea in the Landscape

Although they will tolerate full sun in Northern climates, Ah-Ha® needs partial shade everywhere else. Try them on the east side of your house, or skirting taller trees and shrubs as facer plants. Add a long border that emboldens your foundation with impressive color! You'll pump up your curb appeal in a single step! For a continuous ribbon of blooms, plant them 18 to 24 inches apart on center. You'll measure from the center of one to the center of the next.

These tidy mounding shrubs look incredible in front of larger Hydrangea varieties, too. Mix and match your favorites from all of our extensive options for a grand, easy-care landscape. Incorporate Ah-Ha® into your mixed borders, or create a low, informal hedge. You can even place them in large outdoor containers if you want to elevate the lovely blooms closer to eye level. Try a pair of containers flanking either side of your front door. Pop one under an old evergreen tree to boost the color saturation.

Look for opportunities to make your guests smile. Could you use one or more at your garden gate? Or tuck it behind a fun garden sculpture to heighten the impact. Oh, and by the way...this desirable shrub makes a perfect gift for a plant lover!

#ProPlantTips for Care

Plant Tuff Stuff Hydrangeas in full sun in cooler climates, but give them partial shade where summers get hot. They require at least four hours of direct sunlight a day, and the morning sun is preferred. Be prepared to give them a consistent schedule of even moisture during summer heat too. Place a three-inch layer of mulch over the roots to keep the plant nice and cool. There is blessedly no need to trim the stems. However, you can easily deadhead the spent blooms just below the large flower heads, for a trim and tidy look.

They need well-drained soil but are adaptable to either acidic or slightly alkaline soil. You can expect to see bluer blossoms in the lower pH of acidic soil, and pink in the higher pH of neutral to alkaline. Color changes can occur due to the soil pH over time using garden Sulphur for blue. Try garden lime for pink blooms. Be patient with your experiment, and get an inexpensive soil tester to ensure you don't overdo it.
