Planting & Care

Where to Plant

  • Sunlight: Aim for about 4 to 6 hours of direct sun to ensure the best bloom color and stem strength. In hotter climates, provide protection from the intense afternoon sun to prevent wilting, while gardeners in cooler zones can plant in full sun.
  • Soil: Plant in rich, well-draining soil that stays evenly moist without becoming waterlogged. If your soil is heavy clay or very sandy, mix in compost or peat moss to improve texture and hold the right amount of moisture.

Watering Requirements

Give this shrub consistent moisture throughout its first year to help the shallow root system establish. While it becomes more resilient once settled, inconsistent watering often leads to wilting leaves and significantly fewer flowers during the rebloom cycle.

Pruning Tips

Since this variety blooms on both old and new wood, avoid cutting it back hard or you will lose the first flush of flowers. Simply trim off any dead wood or winter-damaged stems in early spring to tidy up the plant and encourage vigorous new growth.

Fertilizer Needs

Apply a slow-release granular fertilizer formulated for flowering shrubs or roses in early spring just as new leaves emerge. Avoid high-nitrogen fertilizers late in the summer, as this encourages soft growth that will not survive the winter cold.

#ProPlantTips for Care:

Plant Hydrangea shrubs in well-drained soil that is organically enriched in any full sun or partial shade location. Appreciating afternoon shade in hotter climates, Hydrangea also needs a good layer of arborist mulch over the root system to insulate them and keep moisture in the soil more consistently.

Considered an "everbloomer" you really need to see Tuff Stuff™ Hydrangeas to understand their sheer flower power. Since it blooms on old AND new wood, it is an almost non-stop bloomer from early summer and well into fall! Prune your shrub only to remove dead wood in spring, after the new growth begins to emerge. Because these bloom on old and new wood, pruning too much will remove the new flowers! Renewal pruning is best to keep them blooming by removing only one-third of the oldest, fattest stems every 3-5 years, leaving the youngest stems to bloom abundantly.

Mountain Hydrangeas are slightly dependent on soil pH and their pink blooms may take on more of a blue to purple hue. Play with this to your advantage and tweak these shrubs to match them to your garden's décor.

Tuff Stuff™ Hydrangea love moisture and sun but are wonderfully adaptable and mix and match beautifully with each other! Mix Top Fun™ with Ah-Ha® or Tuff Stuff™ Red for a range of flower colors!
