Hydrangea Care


Hydrangeas are  deciduous shrubs or small trees. They are grown for their beautiful domed or flattened flowers which appear in mid-summer for a month.

The flowers normally consist of a mass of fertile flowers surrounded by infertile flowers which give the hydrangea its large flower heads. Some varieties however have almost all sterile flowers.

Hydrangea arborescens and quercifolia are natives of North America, Hydrangea serratifolia is native to South America. The remainder of hydrangeas are natives East Asia.

Recommended for the amateur and experienced gardener.

Message: Last year I bought and planted 3 Mophead Hydrangeas (in flower at the time). When the flowers were dead and gone brown I cut the plants down nearly to the ground. They have now doubled in size and look very healthy but..... they have no flowers! I realise now that I shouldn't have cut them down but my question is :- if I leave them alone, will they flower next year?

Message: Have been growing white hydrangeas for 5 years in my garden; these were previously in my parents' garden for some 30 years. This year they are being attacked by micro sized brownish bugs which travel up the veins of leaves. We also have blue and pink hydrangeas but these seem to be immune from the bugs.
