Nikko Blue Hydrangea Bush

Our Nikko Blue Hydrangea Plant is considered one of the most consistently blue-colored hydrangeas; Nikko will change color with the pH of your soil, as do most, though the color-change will not be quite as dramatic as some. Maintaining its blue coloration in a variety of soils, more neutral or alkaline conditions will result in a purplish-blue coloration, while acidic soils will result in brilliantly sky-blue mophead blossoms. Sunlight will not change the color, which makes these ideal for brightening up shaded areas; in coastal areas, these moderately salt-tolerant shrubs just need a little protection from direct salt spray. They dry beautifully as well!

Planting Instructions:

• - Can be planted anytime the soil temps are 60F

Soil Preparation:

• - Ideal soil pH: 6.0-7.0, though varies by species
• - Prefers well-drained soil with organic matter for most bush varieties

Watering Specifics:

• - Water thoroughly when first planted, allowing soil to dry slightly between waterings
• - Once established, most bushes are drought-tolerant but benefit from regular watering during dry spells

Fertilizer Type:

• - Apply a balanced fertilizer in early spring to promote healthy growth
• - Avoid over-fertilizing, as this can promote excessive foliage growth at the expense of blooms

Pruning and Training:

• - Prune in late summer after the flowers fade, never in the spring
• - Up to one-third of the stems length can be pruned back

Additional Pest Management:

• - Most bushes are pest-resistant, though monitor for aphids, mites, or scale insects depending on the species
• - Ensure good air circulation to prevent fungal issues in dense growth

Temperature Tolerance:

• - Tolerates heat and cold once established
