Hydrangea macrophylla

Hydrangeas like part shade and cool, rather acidic soil. Planted in spring or autumn, they flower June to September. The March prune must stay light: they bloom on last year's wood.

The tips that matter

  • Remove only dead wood and spent heads (above the first fat bud): hard pruning costs a full year of bloom.
  • Pink in chalky soil, blue in acid soil: to blue them, add crushed slate or aluminium sulphate.
  • Leaves scorching in afternoon sun mean a wrong spot — light afternoon shade is a must.
