Flowering Months
Feed and water container grown plants regularly. As plants increase in size they will require repotting into increasingly larger pots. In autumn, apply a mulch of well rotted manure or garden compost to the base of border grown plants. Leave faded hydrangea flower heads in place until new buds swell the following spring. These will help protect the delicate buds from frost damage. Prune stems in spring, removing any rubbing, damaged or diseased stems and reducing stems to maintain a permanent woody framework.
Caution: irritant to skin and eyes, harmful if eaten. When growing hydrangeas, choose a sunny or semi shaded spot that is sheltered from cold winter winds. Plant in borders in rich moist, well drained soil. Add plenty of well rotted manure to improve heavy clay or light sandy soils. Alternatively plant hydrangea in patio containers in soil based compost such as John Innes No. 3.

new for the garden 2013-09-20

Ordered this because I have never grown Hydrangeas before and this particular specimen was very colourfull, it arrived well packed and looks great in the corner of the garden, I planted Pansies in fron of it and it looks splendid.

something different 4 the garden 2012-11-22

ordered one of these for my parents as hydrangeas grow well in there garden they are was pleased with the way the plant was delivered and looked on unpacking they hope to be the talk of the street next year with this coloured plant rather than the pink ones everyone else has.
