Hydrangea macrophylla; perhaps one of the best known garden plants. Originally from Japan these robust and reliable plants produce a truly amazing display in summer and autumn. Blue Wave is an unusually strong and hardy grower; this distinctive plant will bloom with beautifully shaped blue flowers in acid soils. Numerous large ray flowers circle the tiny center flowers amongst the supporting dark green foliage. When grown in light shade there are few flowering shrubs of any kind which can equal the beauty of Blue Wave. If you have a slightly alkaline soil treatment with Hydrangea bluing agent may help ensure the flower colour. If the soil is very alkaline you should grow in a pot with ericaceous compost or create a bed with acidic soil.  Very easy to grow; it can be grown in the garden or in a pot or container. In containers use a good quality John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade; become too packed and choke the roots. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 8-9 month applied in the early spring. One application gives all the nutrients the plant requires for the whole year. John Innes is a soils based compost.  A vigorous grower that will need pruning. After flowering prune back to close to the old wood. If the plant becomes too large a more drastic pruning can be undertaken!
