Rose Garden Promise

Source Gardening resources > Factsheets

So your into self-abuse and want a Rose garden. Some gardeners will say planting and maintaining a Rose garden is easy, to them I say, that’s a damn lie.

Maybe it’s my sometimes harsh weather conditions, but, Roses have never been easy for me to grow. They don’t seem to like my clay based soil nor my hot and often windy spring and summers.

The experts tell me that to be successful I need:
* At least six hours of sunshine, preferably morning sun that will quickly dry.
* To be grown without competition from the roots of large trees.
* To have good drainage, however roses can be grown in a raised bed or on a slope to avoid standing water.
* Protection from hot afternoon sun or forceful wind good quality soil with plenty of organic matter.

  • The ideal pH for roses is between 6.5 and 6.8. The soil can be improved with organic matter such as well rotted manure or compost. Phosphorus should be added at planting time for healthy root growth. Apply fertilizer during the growing season to encourage repeat blooming.

    Proper watering of roses can ward off diseases and insects. Irrigate each rose deeply. The amount of water required by the plant depends on its stage of growth. Roses need more water when they are coming into flower. Water less often if the flowers are being cut, and water sparingly before the new growth starts.

    Mulching with organic matter is a good way to keep roots cool in summer, retain moisture, and control weeds. Apply two to three inches of peat moss, ground bark, or composted leaves. This mulch will also help improve soil structure.

    Pruning in the spring. Remove damaged or dead canes, shaping the plant, and opening up the interior for better air circulation. Prunings canes as well as leaves, may contain dormant fungal structures, cankers, and insect eggs. This debris should be buried deep under ground, burned or sent to the landfill. Pruning low to the ground reduces the probability for pest survival

    Table 3 – Disease Management
    Disease Symptoms Treatment
    Black Spot Circular to irregular shaped black spots on the upper surface of the leaves,
    leaf yellowing, leaf drop, canes with raised purple-red blotches that turn
    black with age.
    Carefully prune and discard or destroy affected plant parts when foliage
    is dry. In autumn, rake and discard or destroy all fallen leaves, fruit
    and branches. Spray with an approved fungicide or with the mixture of baking
    soda and horticultural oil as described in Pest Management Around the Home.
    A multipurpose rose spray may be purchased.
    Botrytis Blight Damage mainly occurs in storage. Damage often found near ends of canes
    from which flowers were cut, small flecks and patches on petals, spotting
    on canes.
    In early spring, remove winterkill branches that may harbor the fungus.
    During the growing season, prune and discard or destroy any plant parts
    with symptoms, avoid crowding. Cultivars that prove particularly susceptible
    should be replaced with resistant varieties. If wet conditions develop,
    apply fungicide according to recommendations in the publication Pest Management
    Around the Home.
    Crown Gall Proliferation of tissue forms overgrowth or galls usually located near
    the soil line or around the crown region.
    Remove and discard or destroy infected plants and soil immediately surrounding
    the plants. Consider planting other species of plants in sites where rose
    crown gall infection is severe. Treat new bare root plants according to
    recommendations in the publication Pest Management Around the Home.
    Powdery Mildew Powdery white growth covering the leaves upper surface, leaves may become
    distorted.
    Avoid crowding, prune to thin plants and plantings to improve air circulation.
    In autumn, rake and discard or destroy all fallen leaves, fruit and branches.
    If disease appears apply fungicide according to recommendations in the publication
    Pest Management Around the Home.
    Rust Orange powdery spores are usually confined to the lower leaf surfaces,
    later in the season upper leaf surfaces have orange/brown spots, young stems
    and sepals may become infected, distorted growth.
    Avoid crowding, prune to thin plants and plantings to improve air circulation.
    When rust pustules are first seen on lower leaf surfaces, apply fungicide
    according to recommendations in the publication Pest Management Around the
    Home.

    3. Lots of good information. One of my favorite roses is the antique Pierre Auguste Renoir. It gets tons of flowers, they almost fully open then BAM! They turn brown. What causes this?

      • Mmmm … Sounds like a bad aphid or spider mite problem.
        It may be helpful, starting ‘before’ bud set, to start a insect control program. There are many insecticides that work well. [follow instructions very carefully.]
        If your more into organic control, One natural method of aphid/spider mite control is spraying the infested rose leaves and flowers with a strong jet of ‘Blue Dawn’ soap water from a hose end sprayer. This knocks the aphids off of your roses and onto the ground. Soap water spraying may need to be done weekly until your Roses are no longer blooming. Hint: Spray in the morning hours to allow your rose plants to dry before sun set.

        Good luck and Hopping you have a insect free rose garden.
