Pollination Information for Moonrock Hydrangea (Hydrangea paniculata ‘Kolmakilima’)

Moonrock Hydrangea is a deciduous shrub that produces large, cone-shaped flower heads. These flower heads are made up of small, fertile flowers in the center and larger, sterile flowers on the outer edges. The sterile flowers serve to attract pollinators, while the fertile flowers produce the plant's seeds.

The primary pollinators for Moonrock Hydrangea are bees, particularly bumblebees and honeybees. Butterflies and other insects may also visit the flowers for nectar, but they are less effective at transferring pollen from flower to flower.

Moonrock Hydrangea is self-fertile, meaning that it can produce seeds without the need for cross-pollination with another plant. However, cross-pollination with another Moonrock Hydrangea or a different cultivar of Hydrangea paniculata can result in greater genetic diversity and potentially stronger, more disease-resistant plants.

In general, Moonrock Hydrangea is a low-maintenance plant and does not require any special attention to its pollination needs. However, providing a habitat for pollinators in the surrounding area can help to increase the number of pollinators visiting the plant and improve overall seed production.

Planting & Care for Moonrock Hydrangea

Planting

Moonrock Hydrangea thrives in well-draining soils with good organic content, and it needs full sun or partial shade to grow properly.

• Dig a hole that is twice as wide and just as deep as the root ball.
• Add compost to the soil before planting to improve drainage and soil quality.
• Place the hydrangea in the hole and backfill with soil, pressing firmly to prevent air pockets.
• Water generously, and mulch to retain moisture and prevent weeds.

Care

Moonrock Hydrangea is relatively low-maintenance, but there are a few things you can do to encourage healthy growth and beautiful blooms.

• Water regularly, especially during hot, dry weather. Hydrangeas are thirsty plants and need plenty of water to thrive.
• Fertilize once a year with a balanced fertilizer, such as a 10-10-10 or 20-20-20 blend. Apply in early spring, before new growth appears.
• Prune in late winter or early spring to remove dead or damaged wood, and to shape the plant if necessary. Deadheading spent blooms can also encourage more flowers.
• Protect against pests and diseases, such as spider mites, powdery mildew, and anthracnose, by keeping the plant well-watered and providing good air circulation.
