Traditional hydrangea macrocarpa are ideal to plant now so that they settle in nicely and flower in their new home as an established plant. They like protection from midday and afternoon sun so are great on the southern or eastern side of the house or in moist shade. Hydrangeas flower in late spring and early summer and should be pruned reasonably hard between Christmas and Australia Day to ensure early flowering the following year.
They love a rich, Zoogro improved soil or are great in tubs with high-quality potting mix. Water hydrangeas frequently coming into and during flowering for spectacular results. A feed twice in spring and once in autumn with a high potassium fertiliser increases flower formation and duration. White hydrangeas are always white but the other colours can vary slightly due to soil pH.
