Background

Hydrangea can be deciduous or evergreen shrubs, or self-clinging climbers, with flowers in clusters usually comprising both small fertile and more showy sterile flowers; often good autumn colour. Other common names hydrangea ‘Mariesii Perfecta’.

Hydrangeas give their best blue flowers on acidic soils with a pH 5.5. When grown on neutral soil, (with a pH of 7), the flowers will predominantly be pink, although you may also get blue or mauve blooms. If you want to make sure that your Hydrangea has blue-toned flowers, you will need to make sure your pH does not creep above 6.5. To lower the pH on a neutral soil, you can treat it annually with aluminium salts. It’s much harder however to alter the pH of limey (alkaline) soil, so it’s much easier to grow white or pink hydrangeas instead.

Things to Remember

  • Possibly watering with hard tap water might make them go Pink.
  • Hydrangeas do not like to dry out. In dry weather, soak the roots with a hose and the plant will usually recover.
  • Remove faded flowerheads in spring after the danger of frosts, cutting back the flowered stems to a strong pair of buds.
  • Take out misplaced or diseased shoots.
  • Mulch young plants with a well-rotted manure or compost in spring.
  • Once established, remove a quarter to a third of the shoots to the base of the plant.
  • It makes an excellent cut flower.
