Pollination Info for Climbing Hydrangea (Hydrangea anomala subsp. petiolaris)

Climbing hydrangea is a self-fertile plant, meaning that it is capable of pollinating itself.

However, the climbing hydrangea is known to attract bees, butterflies, and other pollinating insects with its showy white flowers, which are rich in nectar and pollen.

In the wild, climbing hydrangea is pollinated by bees and other insects that are attracted to its flowers. These insects transfer pollen from flower to flower as they feed on nectar and collect pollen.

If you are growing climbing hydrangea in your garden, you can help promote pollination by planting other types of plants that attract pollinators or by providing nesting habitats for bees and other insects.

Planting:

Climbing hydrangeas prefer well-draining soil, but can tolerate a range of soil types. Choose a spot with partial to full shade, as the plant does not thrive in direct sunlight. Dig a hole twice the size of the root ball and backfill with organic compost or topsoil. Water thoroughly after planting.

Care:

Water regularly, especially during hot, dry weather. Climbing hydrangeas do not require much pruning, but can be trimmed after flowering to shape the plant or control its size. Fertilize in the spring with a slow-release fertilizer or compost. Mulch around the base of the plant to retain moisture and suppress weeds.

Climbing hydrangeas attach themselves to surfaces with aerial roots, but may need some initial support when first planted. They can grow up to 80 feet tall, so make sure to plant them near a structure or tree that can support their weight.
