#ProPlantTips For Care
Magical® Ruby Red is hardy in USDA growing zones 5 through 9. In the cooler zones, it tolerates full sun, while in warmer climates afternoon or part shade is appreciated to help the plant remain well hydrated and not wilt.
Ruby Red Hydrangea prefers consistently moist, cool soil. Though not particular on soil type, they won't do well in soggy soil or in conditions that dry out for long periods of time.
Hydrangea grows in about any type of clay, sand or loamy soils however, they do their absolute best in rich, organic, humusy soil, even tolerating salty conditions.
A generous layer of mulch helps retain consistent soil moisture as well as insulate the root system from both the heat and winter's chill.
No pests or disease issues, these are a spectacular variety of a hardy US native Hydrangea. With little worry about damage from deer, these woodlands edge plants won't mind being planted in out-of-the-way areas.
Pruning is best done only in late winter and early spring before you see new growth and only if needed. This way you will not inadvertently remove any of the glorious blooms!
Take care when applying lawn fertilizers near flowering shrubs. These high nitrogen formulas are designed to produce foliage, but will not support flower development. Instead, apply an all-purpose fertilizer for blooming plants in early spring. Reapply in mid-summer, following label directions for application rates.
Ruby Red Hydrangea's bloom color won't change much depending on your soil pH however, in acidic conditions, you may see more of a purple to a blue hue. Adding garden lime will help maintain an alkaline pH for the deepest color saturation possible!
Your garden will become your favorite setting with the Magical® Ruby Red Hydrangea as its crown jewel! Call to order your landscape gems from Nature Hills Nursery today!
