There is to be a bumper berry haul this month predicts the Royal Horticultural Society.

A warm and dry start to the year followed by July and August rains have contributed to many berry-yielding plants, including spindle bushes (euonymus), firethorn (pyracantha), and crab apples, ripening early.

As a result, they are less susceptible to the autumn rots and moulds that blight many in the later weeks of autumn and so are likely to give a longer than average display of seasonal colour.

The bountiful showing of reds, blacks, yellows and purples contrasts the plight of apples, whose flowers were stifled by a spring frost in some regions. With ornamental berries flowering later and their smaller fruits ripening more quickly than apples, gardeners will find some consolation this autumn.

Guy Barter, chief horticulturist at the RHS, said: “The public should revel in the wealth of colour that will dot gardens this month, while plant centres are likely to see a surge in sales of those plants now displaying their beautiful berry wares.

“Edible varieties feature less at this time of year but autumn raspberries are yielding lavishly and mulberries are still producing their luscious fruits. All of the berries will mature in the predicted warm spells this September and contrast gloriously with autumn colour from October, before being consumed by birds including blackbirds, finches, starlings, fieldfares and redwings and other wildlife.”
