How to Grow
The best time to plant your Hydrangea arborescens ‘NCHA5’ INVINCIBELLE WEE WHITE is typically in spring or early fall, allowing the root system time to establish before temperature extremes. Aim for locations with average, medium moisture, well-drained soils, prioritizing part shade for the best leaf health. While this Smooth hydrangea is adaptable, be aware that its foliage declines quickly in dry conditions, so consistent moisture is crucial, especially if planted in areas receiving more sun exposure.
Watering should remain consistent, particularly during establishment and dry summer spells. Although adaptable, this plant is intolerant of drought. Pruning offers excellent control over form and vigor; blooming occurs on new wood. Therefore, you can prune Hydrangea arborescens ‘NCHA5’ INVINCIBELLE WEE WHITE back close to the ground in late winter to encourage strong, vigorous new stems and the best shape for the season.
If severe winter conditions cause the stems to die back completely, do not worry; simply remove any damaged or weakened stems in early spring as needed. This robust pruning strategy ensures that you maintain the desirable compact size and heavy flowering typical of this cultivar.
Landscape Uses

Beyond the garden bed, this manageable shrub excels in containers on patios or decks, bringing vertical interest where space is limited.

Potential Problems
Many species of hydrangea, including this Smooth hydrangea, are susceptible to various fungal and pest challenges.

Companion Planting Guide

Ferns, especially Japanese Painted Ferns or Autumn Ferns, provide excellent textural contrast beneath the shrub’s canopy. Hostas are reliable partners, offering bold, cool-toned foliage that complements the bright white blooms of the Smooth hydrangea.
For vibrant summer color that thrives in part shade, pair this shrub with Astilbe or Impatiens. These flowering perennials enjoy the medium moisture levels this Hydrangea prefers, creating a lush, layered look that remains appealing even when the main blooms slow down. Always ensure adequate spacing to allow for good air movement, reducing the risk of mildew.
Seasonal Care Calendar
Late Winter is the prime time for invigorating your Hydrangea arborescens ‘NCHA5’ INVINCIBELLE WEE WHITE. Because this shrub blooms on new wood, pruning the stems back close to the ground encourages the strongest, freshest growth and best stem support for the coming season. If winter damage is severe, a hard cutback will force healthy regrowth.
From Spring through Summer, focus primarily on consistent watering. Avoid letting the soil dry out completely, as the foliage of the Smooth hydrangea quickly shows signs of stress under drought conditions. There is generally no heavy feeding required; an application of balanced, slow-release fertilizer in early spring is often sufficient for this tough plant.
In Fall, allow the foliage to display its natural yellow tones before leaf drop. Unlike some other hydrangeas, deadheading the spent blooms is often unnecessary, as pruning occurs drastically in late winter anyway. Clean up fallen debris promptly to reduce overwintering sites for potential pests or disease spores.
