It's been a good year for the roses down at the Royal Horticultural Society’s garden in Surrey.
Just take a look at these magnificent blooms, which have grown to twice their normal size.
The secret? Well, the hot weather has certainly helped, but the key ingredient might come as a surprise to many.
Experts at the society’s gardens in Wisley have been using concentrated essence of garlic to help the roses thrive.
The Royal Horticultural Society’s garden in Surrey have experienced a good year for roses, with growth of up to twice their normal size because of a special ingredient
While in legend it is used to ward off vampires, in the garden the pungent cooking ingredient – nicknamed the ‘stinking rose’ – wards off the bane of many a rose-grower’s life: Black spot.
The fungal disease is the rose’s most feared enemy because left unchecked it will stunt the plant’s growth and leave it looking a sorry sight.
Ben Warren, garden team leader at RHS Wisley, said: ‘This year has been a good year for roses due to the weather.
‘The rose Sally Holmes is a good example. This year it has grown twice the size it has ever been.’
While typically the blooms are up to three-and-a-half inches in diameter, this year many are double the size. He added: ‘At Wisley we fumigate the roses with a concentrate of garlic to create a barrier against black spot.’
Experts at the society’s gardens in Wisley have been using concentrated essence of garlic to help the roses thrive.
The garlic spray is a commercially available mixture called Garshield, which the maker says leaves no taints or flavours and is odourless within minutes of being applied. Some gardeners make their own mixture by putting three garlic bulbs in a food processor, whizzing it up with water, straining it and spraying it on plants.
The rose Sally Holmes is described in the David Austin catalogue as a strong-growing shrub with plentiful, creamy white, semidouble flowers held in large bunches. It is nearly always in bloom, and lightly scented, ideal for attracting bees, and good in all soil types.
n Britain’s rose gardens are at risk from a foreign virus which has caused devastation in the US and Canada, plant scientists have warned.
The rose rosette virus causes distorted leaf growth and deformed stems and flowers.
All varieties of roses are considered to be vulnerable to the virus, which is carried by a mite called an eriophyid which can be blown by the wind.
The Department for the Environment, Food and Rural Affairs has ruled that all rose plants and cut flowers imported from Canada, India, Mexico or the US must be accompanied by a certificate confirming that they were grown in an area free from the virus.
