How to Grow a Shreveport Grandiflora Rose in Canada
The Shreveport Grandiflora rose is one of the most extravagantly fragrant rose bushes in the genus Rosa. The Shreveport was originally introduced as a patented hybrid rose in 1981. You can grow a Shreveport Grandiflora rose bush outdoors in Canada if you live in a temperate zone that rarely falls below 32 degrees Fahrenheit in winter. If you live in a colder region, then you'll need to arrange a suitable indoor growing space for your bush. Does this Spark an idea?

1
Navigate to the Canadian government's Agriculture and Agri-Food website to determine whether your local climate is suitable for growing a Shreveport Grandiflora Rose in the outdoors (see Resources).
-
2
Determine the color on the map that corresponds to the locale in which you live. The Shreveport Grandiflora can be grown in climate zones in which the lowest wintertime temperature is no colder than 32 degrees Fahrenheit; this corresponds to plant hardiness zones 7a and higher. If your region is colored warm orange, pink, or lavender, then you may grow your Shreveport Grandiflora outdoors. These zones correspond primarily to areas in western British Columbia, southern Ontario, and coastal Nova Scotia and Newfoundland.

Arrange for indoor growing if you live in a plant hardiness zone that is rated 6b or colder. You'll need to find an indoor location that does not drop below 32 degrees Fahrenheit and receives at least six hours of sunlight per day. The container in which you plant the pot should allow for free drainage and should provide at least 18 inches of space for the bush's roots.
-
4
Determine the acidity of the soil in which you plan on planting the bush. Roses prefer a soil that is mildly acidic; a soil pH between 5.5 and 7.0 is ideal for rose growing. You can determine the acidity of the soil using a basic pH testing strips that you can purchase at any nursery or store with a gardening department.
-
5
Modify the acidity of your soil if it falls outside the 5.5 to 7.0 range. Add elemental sulfur to the soil if the pH is too high; add lime to the soil if the pH is too low. See Resources for information on the amount of sulfur or lime that you'll need to use to achieve the desired pH.
-
6
Plant your Shreveport Grandflora rose bush. If you are planting multiple bushes in an arrangement, be sure to leave 24 to 36 inches between each bush.
-
7
Fertilize your roses at the beginning of the spring growing season and in summer after the first round of blooms is complete.
-
8
Prune your rose bush on a regular basis. Cut out any dead canes immediately, and remove any stems that are thinner than a pencil. Removing these inactive areas will allow the rose to use its resources and energy to produce blooms on the healthier portions of the bush.
