How to Plant Hydrangea ‘Groundbreaker Blush’

1. Choose a spot – sheltered, lightly shaded, with space to spread.
2. Prepare soil – dig in compost or well-rotted manure.
3. Planting depth – place at the same level as in its pot.
4. Backfill and firm – gently press soil around the base.
5. Water well – soak the rootball thoroughly.
6. Mulch – apply bark or compost around the base.

Feeding

• Spring: Balanced slow-release fertiliser.
• Summer: A potassium-rich feed (like tomato fertiliser) for flowers.
• Avoid excessive nitrogen, which encourages leaves over blooms.

Pruning Hydrangea ‘Groundbreaker Blush’

• When to prune: In spring (April), after frost danger has passed.
• How:
  • Cut back faded flower heads to just above a strong bud.

  • Avoid cutting too hard, as this removes future blooms.

Seasonal Interest

• Spring: Fresh green leaves emerge.
• Summer: Abundant pink mophead blooms dominate.
• Autumn: Flowers fade to antique shades; foliage turns golden.
• Winter: Dried flower heads provide frost protection and interest.
