Hydrangea Cityline® Mars is a must have shrub with its huge blooms, compact habit and mildew free foliage.

Hydrangeas have long been a staple for the summer garden and nothing is more showy than the big, billowy blooms of macrophylla Cityline® Mars.

Cityline® Mars is super compact!  At only 36" tall. They are an ideal fit for smaller spaces or even container gardening!

Cityline® Mars forms a nice mounded habit. They begin their flower show in summer with distinctive two-tone blooms ranging from deep indigo-blue to magenta-pink (depending on soil type), and mature to a pleasing green by fall.

Garden design enthusiasts are also appreciating the usefulness of this hybrid whether as a low growing hedge plant, single specimen, or even a foundation plant up near the house!

Hydrangeas are continuing to take the flowering shrub world by storm. They are widely adaptable to both clay and sandy soil provided they are given copious amounts of water during the prolonged summer dry spells. Almost all Hydrangeas thrive under morning sun with protection from the intense afternoon sun. This queen of the flowering shrubs allows for a multitude of uses in garden designs including: solitary specimen, mass plantings, or even container gardens. They even make long-lasting cut flowers!

Soil: Best grown in organically rich, medium moisture, well-drained soils.  Generally, a soil pH below 5.0 results in deep, vivid blues, and as the pH rises, the flowers range from blue to lavender to mauve to a vivid deep pink at pH 7.0 (neutral). The pH determines the availability of aluminum in the soil; this element is more readily available in acid soils, and this availability results in the blue flower color. Since phosphorus ties up aluminum in soils, using a fertilizer low in this nutrient will aid in attaining blue flowers. If pink flowers are desired and your soil is acid, simply add lime to raise the pH and use a balanced fertilizer. Aluminum sulfate will lower pH if blue flowers are desired.
Light: Most varieties tolerate full sun in the North, but benefit from afternoon shade. Tolerates 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. Mulch to conserve moisture and buffer soil temperatures, keeping mulch a few inches away from main stems to avoid rot.
Spacing:  3 feet
Fertilizing:  Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15).
Winterizing: Remove and destroy any fallen foliage that was infected by powdery mildew. You may wrap with burlap or other protective covering to help preserve flower buds through a cold winter.
Maintenance & Pruning:  This variety blooms on old wood. Any pruning should be done before August (to be safe). Due to its compact habit, it rarely needs much in the way of shaping. You can remove some of the oldest stems at ground level to thin out the shrub as needed. In spring, only prune out dead wood once the new growth has emerged. Young plants may be transplanted when dormant in early spring.
