A GOOD YEAR FOR ROSES
Climbing rose Morning Jewel |
Rose growers could not have
asked for better weather. Provided the rose beds and borders got some
irrigation, plant growth has been strong and very healthy, responding to our
recent near tropical weather. However, just when the first heat wave was ending
and rain returned, so did the strong gales and damaged any long shoots on both
bush and climbing rose. Then the tropical weather returned and plants again
just loved it.

I had thought that my tall
climbing rose Dublin
Bay was a goner as the
gales broke off a lot of flowering shoots, but there was still plenty unopened
buds ready to replace the losses. Similarly my shrub rose Gertrude Jekyll,
which I train as a climber lost a lot of flowers, but still put on a great
show. It suffered a lot of greenfly infestations during May, but these got
washed off while watering the garden and putting on a high pressure spray,
carefully. Roses have always created the main floral impact in summer, as I
grow shrubs, climbers and bush types, though they may have lost the popularity
they once held when in my youth. They were a symbol of wealth for both
gardeners, home owners and Leisure
departments of towns. Both Dundee and Aberdeen and many other towns grew and
planted them by the thousand, but sadly today most have all vanished. My early gardening experience in my training
years, was to buy 100 Rosa canina rootstocks
then with a broken pen knife, I budded them in summer and got over 80 bushes
for my garden. Several years later while studying at college in Chelmsford I
did a project researching rose breeding and came across another rootstock, Rosa
multiflora. It was said to give far superior results, so I purchased another
100 and budded these. Commercially this rootstock would not be acceptable in
the trade as the neck between roots and stem is too small making budding
difficult and slowing down the budders, but my bushes were fantastic. Each bush
had more flowering shoots than normal, and each shoot had more flowers than
normal. My garden was a mass of colour. Today growers prefer to use Rosa laxa
as this does not sucker as much as Rosa canina. Roses may not be so popular,
but they are in my blood, so my garden would be empty without them.

Ispahan |
Over the years the large
number of rose varieties has been whittled down as any bush liable to infection
from the common rose diseases would get discarded as chemicals used for their
control have just about all been withdrawn. There is still a few chemicals
available for diseases of roses, but I tend to only grow those with strong
healthy foliage able to withstand attacks of fungi.
Shrub roses now include
Ispahan,
Lavander Lassie, Wisley, Gertrude Jekyll and Rosa Mundi, though the
recent gales blew Rosa Mundi over just as it was coming into flower.

Climbers able to stand up to
diseases include Mme Alfred Carrier, Dublin Bay, Iceberg, Ena Harkness and the
pink Morning Jewel. Climbing Ena Harkness is a sport of the bush variety and
suffers the same weak neck which can’t hold up the large deep red and scented
flowers, but in the climbing form this is an advantage. The flowers bend down
so you can see them.
Gertrude Jekyll |
My favourite bush roses
include, the yellow Arthur Bell, the red E H Morse, the white Iceberg and
Margaret Merril, and pink Congratulations, Miriam and Dearest, and Piccadilly
is a great bicolour as is Rose Gaujard.
For the perfect red rose
bloom, National Trust almost fits the bill, but sadly it is not scented,
whereas Fragrant Cloud has a great scent. Super Star may have been the first
orange rose way back in the sixties, but now Alexander and Dawn Chorus are the
popular choices. For the best scented rose try Wendy Cussons, a deep pink
hybrid tea type, which won the Clay Vase for fragrance.
Anna dead heads the sweet peas |
Wee jobs to do this week
Dead head rhododendron and azaleas, bedding plants in tubs and borders,
herbaceous plants, roses, and sweet peas. This encourages the plant to continue
growing and producing more flowers rather than setting seeds.
Spray an insecticide on Rhododendrons and Camellias against scale growing
on the underside of the leaves to prevent a build up of sooty mould.
