PLANT ROSES
Roses were at their
most popular about fifty years ago. No garden was complete without a few roses,
and Dundee Parks department propagated them by the thousands every year for
brightening up the parks, town centre and outdoor landscapes. They were also
functional used to deter trespass with varieties like Rosa omeiensis
pteracantha with
spectacular thorns totally covering the stems. As air
pollution improved over the years rose diseases gained a foothold as the
pollution had acted as a mild fungicide. Unfortunately so many varieties
suffered severe loss of leaves from blackspot, rust and mildew that they were
not worth growing. Rose breeders
were left with the task of finding new
varieties with strong disease resistant foliage while still having attractive
flowers and a scent where ever possible. I have grown hundreds of different
varieties over the years, and discarded very many, but there is still a good
roses well worth growing and every year new varieties appear in nurseries and garden
centers to try out.

Roses come in many
forms from miniature to bush (floribundas and hybrid teas) then shrubs,
climbers and ramblers, so you can choose a plant to suit any occasion. Always
buy from a reputable source and keep your receipt and the label. I have had
several purchases where the plant did not reflect the label. One lovely red
bush rose turned out to be a disease prone pink rose, and a dazzling yellow
Julie Goodyear from a local garden centre does not seem to exist except in my
garden.

Roses can be grown
against walls, fences, up pergolas, or in borders as miniatures, bushes or if
you have plenty of room free standing shrubs. Make sure you read about the
ultimate size as some can be quite enormous. My climbing Mme Alfred Carrier
wrecked my six foot fence then stretched well over twenty feet in every
direction. However it is such a beauty that I cut it back to young shoots about
six feet long so it can have another lease of life for a few more years.
I grow a deep red
Dublin Bay on my south wall of the house and it flowers all summer from ground
to twelve feet tall making a spectacular show, but unfortunately it has no
scent. Another shrub rose I converted to a climber is the pink scented Gertrude
Jekyll which never lets you down. It gets a wee bit of mildew, but nothing
severe and greenfly can be a problem, but a couple of insecticide sprays sorts
them out. It is a real show stopper on the house wall on
our patio.

Another of my favourite
shrub roses, Ispahan has quite disease free foliage and is a mass of old
English pink flowers in summer, but it can grow ten feet tall so either keep it
pruned or if you have the space let it grow naturally.
Bush varieties are
numerous in all colours and dependable varieties include the pinks Dearest and
Myriam, the red scented E H Morse,
the bicolors Piccadilly and Rose Gaujard,
the golden yellow Arthur Bell and Julie Goodyear (if it exists), and my best
orange is Dawn Chorus.

Roses are propagated
commercially by budding, but the home gardener can propagate roses with hardwood
cuttings about 9 inches long, taken in the dormant season and lined out six
inches apart with half the cutting buried in the soil. They should be ready for
replanting the following winter.
Cultivation
Roses grow best on fertile clay soil provided it is well drained. Always dig deep and add plenty of compost as the bushes will last ten or more years. Plant about eighteen inches apart and add some fertilizer in spring to give growth a boost.

Amaryllis just potted up |
Wee jobs to do this week
Amaryllis bulbs can
be potted up now for flowering 7 to 10 weeks later. Pot them up in pots just
slightly larger than the bulb using good potting compost. Leave one third of
the bulb above the compost surface. Keep in a light warm spot and do not over
water. The strong flower spike arrives before the leaves. After flowering keep
the plant watered and fed to build up bulb strength so it can flower the next
year, but it needs a good two months dormant period so slowly dry off in
September. It can spend the summer months outdoors in a sheltered spot.
