Rose Growing Guide
Crop Rotation Group
Rich, well-drained soil with compost dug in. A slightly acidic pH of 6 to 6.5 is preferred.
Full sun to partial shade.
Some roses are hardy to -40C (-40F), but most popular cultivars can be badly injured by temperatures below -23C (-10F). Choose varieties that are known to grow well in your area.
Fertilise in spring by spreading a 1-inch (2.5 cm) layer of composted manure over the root zones of the plants. Feed plants again in early summer, just after the first big flush of blooms. A final feeding in late summer is needed in warmer areas where many roses rebloom heavily in the autumn.
Single Plants: 90cm (2' 11") each way (minimum)
Rows: 60cm (1' 11") with 1.50m (4' 11") row gap (minimum)
Sow and Plant
Plant bare-root roses while dormant during Autumn and Winter. Container-grown plants can be set out year round in most areas ifcare is taken to provide extra water in warmer conditions. Mulch after planting to keep the soil moist, and to limit splashing of soil onto the leaves.

Disease-resistant shrub roses need no spraying and rebloom several times during the season. Trim back all roses after they bloom to reduce problems with disease. In some areas, a deep winter mulch is needed to protect grafts and dormant buds from winter injury.
Many roses produce fleshy berries, called rosehips, that make a nutritious and flavorful addition to teas. Harvest them for drying when they turn from green to orange or red.
Aphids are common on new growth in spring, but numerous natural enemies usually control them. Rose black spot, powdery mildew, and other diseases can be serious, and are best prevented by growing resistant varieties.
