The ‘Hydrangea Enziandom’ is a popular cultivar, valued for its striking blooms and foliage. Offering dependable performance and vibrant color, it’s versatile for borders or focal points. It enhances any outdoor space, appealing to all gardeners.
Key Characteristics of Hydrangea Enziandom
‘Hydrangea Enziandom’ is a compact, deciduous shrub, reaching 3-4 feet (0.9-1.2 meters) tall and wide. Its dark green leaves turn copper-red in autumn. As a mophead Hydrangea macrophylla, it has large, globular sterile florets.
Bloom color depends on soil pH. Acidic soil (pH 5.2-5.5) yields deep blue; alkaline soil (pH 6.5+) deep pink. Showy flower heads emerge July-August, lasting two months.
Planting and Site Selection
Choose a site with balanced sun and protection. ‘Hydrangea Enziandom’ thrives in part shade; afternoon shade prevents scorching. Full sun tolerated with consistent moisture.
It prefers rich, medium-moisture, well-drained soil. Soil pH dictates flower color: 5.2-5.5 (blue), 6.5-7.0 (pink). Incorporate organic matter (compost) to improve soil structure, drainage, and root development.
Dig a hole twice as wide and deep as the root ball. Remove plant, loosen circling roots, position root ball top level with soil. Backfill with amended soil, tamping out air pockets. Water thoroughly to settle soil and hydrate.
Ongoing Care and Maintenance
Water consistently, especially during dry periods and establishment. Requires consistently moist, well-drained soil. Deep watering 2-3 times weekly promotes deeper roots and drought tolerance.
Fertilize for vigorous growth and abundant blooms. For blue blooms, apply a balanced acid-loving fertilizer in spring. For pink blooms, use a high-phosphorus fertilizer. Avoid excessive nitrogen; it reduces flowering.
Mulching benefits ‘Hydrangea Enziandom’. Apply 2-3 inches of organic mulch (shredded bark, compost) to retain moisture, regulate temperature, and suppress weeds. Mulch enriches soil as it breaks down. For blue hydrangeas, acidic mulches (pine needles) help maintain soil pH.
Pruning Hydrangea Enziandom
Proper pruning is key as ‘Hydrangea Enziandom’ blooms on old wood. Incorrect timing removes buds, reducing blooms.
Prune immediately after flowering (late summer/early autumn). This allows new growth and bud set before winter. Deadhead spent flowers to healthy buds or strong side shoots, improving appearance and encouraging blooms.
Perform structural pruning. Remove weak, dead, or winter-damaged stems in late winter/early spring. Annually cut back one-third of oldest stems for vigorous new growth. This rejuvenation pruning maintains shape and promotes health without sacrificing blooms.
Troubleshooting Common Issues
Lack of blooms often results from improper pruning or winter damage. Late pruning (fall/spring) removes flower buds on old wood. Harsh winter temperatures or late frosts damage tender buds. Winter protection (mulching, covering in USDA Zone 5) mitigates this risk.
Leaf discoloration (yellowing/browning) indicates issues. Yellowing leaves with green veins signal iron deficiency in alkaline soils; acidic pH adjustment corrects this. Browning edges or wilting in hot weather indicates insufficient water or excessive sun. Consistent moisture and afternoon shade alleviate symptoms.
‘Hydrangea Enziandom’ is robust but can encounter pests or diseases. Common pests (aphids, spider mites, scale) are managed with horticultural oil or insecticidal soap. Powdery mildew appears in humid conditions; ensure good air circulation and avoid overhead watering to prevent spread.
