Plant of the Week: Hydrangea

Plant of the Week: Hydrangea

Hydrangeas are among the best-loved of summer shrubs, their showy flowers making an eagerly anticipated spectacle from late July onwards.

They're well known for their curious habit of changing their flower colour in different gardens, and we're often asked why this is. It's a tendency most often seen in mophead and lacecap varieties of Hydrangea macrophylla, which produce blue flowers when soil is acid and pink if it's alkaline.

You can influence this by watering with rainwater, which is more acidic than tap water, and by taking steps to lower your soil's pH using aluminium sulphate 'blueing agents'. Alternatively, grow your hydrangeas in roomy containers of ericaceous (acidic) compost.

Mulch Trees

Mulch established trees now with a good layer of well rotted manure, leaf mould or garden compost, but make sure that the mulch does not touch the trunk this is to prevent pests and diseases harming the bark. Best done after rain so moisture is trapped.
