Whilst all hydrangeas require fairly damp soil conditions they can be grown satisfactorily in drier soil (as at Southern Comfort), provided they are given the occasional bucket of water during dry spells. This blue lacecap (probably Hydrangea macrophylla 'Blue Wave' syn. 'Mariesii Perfecta') requires acid soil to give its best blue. Proprietary colorants or sequestered iron products can be used in other cases. Before growth starts in the following season all hydrangea branches should be pruned back to a healthy vigorous bud. Another good blue lacecap is the almost indistinguishable Hydrangea serrata 'Bluebird'.
