How to Grow and Care for Lacecap Hydrangea

Lacecap hydrangeas (Hydrangea macrophylla) are beloved for their stunning, delicate blooms and lush foliage, making them a popular choice for gardens in Gisborne, New Zealand. With proper care, these beautiful shrubs can thrive in Gisborne’s temperate climate, adding a touch of elegance to any landscape. Here’s how to grow and care for lacecap hydrangeas in Gisborne:

1. Choosing the Right Location:

• Lacecap hydrangeas thrive in partially shaded locations with morning sun and afternoon shade. Avoid planting them in full sun, as this can cause the delicate blooms to wilt.
• Select a site with well-draining soil that is rich in organic matter. Hydrangeas prefer slightly acidic soil with a pH between 5.5 and 6.5.

2. Planting:

• Plant lacecap hydrangeas in the spring or fall, when temperatures are mild and soil is workable.
• Dig a hole that is two to three times wider than the root ball and of equal depth. Backfill with amended soil and water thoroughly after planting.
• Space multiple hydrangea plants at least three to four feet apart to allow for proper air circulation and room to grow.

3. Watering:

• Keep the soil consistently moist, but not waterlogged. Hydrangeas prefer regular watering, especially during periods of dry weather.
• Mulch around the base of the plant to help retain moisture and regulate soil temperature.

4. Fertilizing:

• Apply a balanced, slow-release fertilizer formulated for acid-loving plants in the spring, just as new growth begins. Follow package instructions for application rates.
• Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.

5. Pruning:

• Lacecap hydrangeas bloom on old wood, so avoid heavy pruning in late summer or fall, as this can remove next year’s flower buds.
• Instead, prune lightly in late winter or early spring to remove dead or damaged branches and shape the plant as desired.

6. Managing Flower Color:

• The flower color of lacecap hydrangeas can be influenced by soil pH. Acidic soil (pH below 6.0) typically produces blue flowers, while alkaline soil (pH above 6.0) produces pink flowers.
• To encourage blue blooms, amend the soil with aluminum sulfate. To encourage pink blooms, add lime to the soil.

7. Winter Protection:

• In Gisborne’s mild climate, lacecap hydrangeas generally do not require winter protection. However, if temperatures drop below freezing, consider covering plants with a layer of mulch or burlap to insulate them from cold temperatures.
