Planting Tips

Where to Plant

Annabelle Hydrangea thrives in locations with partial to full sun, though it benefits from afternoon shade in hotter climates. It’s ideal for planting in garden beds, borders, or as a stand-alone specimen.


This hydrangea variety prefers partial to full sun but can tolerate some shade. In regions with intense sun, protection from harsh afternoon rays is beneficial to prevent wilting.


Annabelle Hydrangea grows best in well-draining, moist soil with a rich organic content. It prefers slightly acidic to neutral soil pH.


Space Annabelle Hydrangeas about 4 to 6 feet apart. Proper spacing allows for adequate air circulation and full growth potential of each plant.

When to Plant

The optimal time for planting Annabelle Hydrangea is in the spring or early fall. Cooler temperatures during these seasons promote root development without the stress of extreme heat.

How to Plant

Dig a hole as deep and twice as wide as the root ball. Place the hydrangea in the hole, fill with soil, and water thoroughly. Ensure the top of the root ball is level with the ground.

Plant Care Tips


Regular watering is essential, especially during the first growing season. Annabelle Hydrangea prefers consistently moist soil but does not tolerate standing water.


Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and abundant flowering.


Prune Annabelle Hydrangea in late winter or early spring. Since it blooms on new wood, pruning stimulates healthy growth and larger flowers.

By Season


Spring Care

In spring, apply mulch to retain moisture and control weeds. Begin regular watering and fertilizing as new growth starts.

Summer Care

During summer, continue consistent watering, especially in dry periods. Monitor for pests and diseases, treating as needed.

Fall Care

Reduce watering in the fall and clean up any fallen leaves. No major care is needed as the plant prepares for dormancy.

Winter Care

Annabelle Hydrangea is dormant in winter. Protect the roots with a layer of mulch, especially in colder climates.
