What are the care requirements for Nikko Blue Hydrangea?
The Nikko Blue Hydrangea requires regular watering, especially during the first year after planting. It thrives in well-drained, slightly acidic soil with a pH of 5.5 to 6.5.

Where is the best place to plant a Nikko Blue Hydrangea?

How often should I water my Nikko Blue Hydrangea?
Water your Nikko Blue Hydrangea regularly, especially during dry spells. The soil should remain consistently moist but not soggy.

Prune your Nikko Blue Hydrangea in early spring before new growth begins. Remove any dead, damaged, or crossing branches to encourage better air circulation and more blooms. If you want to shape the plant, prune lightly, as hydrangeas bloom on old wood, and too much pruning can reduce the number of flowers.

Just ensure they receive the right amount of sunlight, water, and have acidic, well-draining soil for optimal growth.

The typical lifespan of a Nikko Blue Hydrangea is around 40 years with proper care, including watering, pruning, and fertilizing.
Can Nikko Blue Hydrangea be grown in cold climates?

How long do the blooms of Nikko Blue Hydrangea last?
The blooms of a Nikko Blue Hydrangea typically last from late spring to early fall, offering long-lasting color throughout the growing season. Deadheading spent blooms can help improve the plant's appearance and encourage more blooms.
Are there any pests or diseases that affect Nikko Blue Hydrangea?
While Nikko Blue Hydrangeas are generally resistant to pests, they may be susceptible to aphids, spider mites, and mildew. Regularly check for signs of infestation and treat accordingly.
