Choosing the right position

• Prefers full sun to partial shade

• Suitable for borders, woodland-style planting, or as a feature shrub
• Choose a sheltered location, protected from strong winds

• Prefers fertile, humus-rich soil
• Tolerates a range of soil types, including clay if well improved
• Performs best in neutral to slightly acidic soil
• Improve soil with compost or well-rotted organic matter before planting

How to plant in the ground

• Dig a hole twice as wide as the root ball and the same depth
• Soak the root ball thoroughly before planting
• Position the plant so the top of the root ball is level with the soil surface
• Backfill with soil mixed with organic matter and firm gently
• Water well after planting to settle the soil
• Apply a mulch around the base to retain moisture

Planting in containers

• Choose a large pot with good drainage holes

• Water thoroughly after planting and allow excess water to drain
• Place in a position with some shelter from strong sun and wind

Ongoing Care and Maintenance

Hydrangea ‘Pink Annabelle’® is easy to grow and provides reliable flowering with the right care.

Watering

• Keep soil consistently moist, especially during the growing season
• Water deeply during dry spells
• Container-grown plants require frequent watering
• Avoid allowing the soil to dry out completely
• Ensure good drainage to prevent waterlogging

Feeding

• Apply a balanced fertiliser in spring to encourage strong growth
• A second feed in early summer can support flowering
• Container plants benefit from regular liquid feeding
• Avoid excessive feeding, which can result in soft growth

Pruning

• Prune hard in late winter or early spring
• Cut stems back to around 15–30cm above ground level
• Flowers are produced on new growth, so pruning encourages larger blooms
• Remove any weak or damaged stems
• Regular pruning helps maintain a compact, tidy shape

Mulching

• Apply a thick layer of organic mulch in spring
• Helps retain moisture and suppress weeds
• Improves soil structure and fertility
• Keep mulch away from direct contact with stems
