Rose Care Guide for BC 

How to Grow Beautiful, Healthy Roses in South Coastal BC 

Roses reward gardeners with months of spectacular blooms, fragrance, and pollinator activity. With the right planting location, soil preparation, and seasonal care, roses thrive in our mild coastal climate. 

 

Choosing the Right Rose 

There’s a rose for every garden style: 

• Hybrid Tea Roses – Large, classic blooms on long stems 

• Floribunda Roses – Clusters of continuous colour 

• Shrub Roses – Hardy, low-maintenance landscape performers 

• Climbing Roses – Perfect for trellises, fences, and arches 

• Groundcover Roses – Spreading habit for borders and slopes

How to Plant Roses 

Proper planting sets your rose up for long-term success. 

Location 

• Minimum 6 hours of full sun daily 

• Good air circulation helps prevent disease 

• Avoid low spots where water collects 

Soil 

• Rich, well-drained soil 

• Amend with compost – we reccomend Sea Soil, Gardenworks Composted Mushroom Manure or Gardenworks Composted Cattle Manure  

• Roses prefer slightly acidic to neutral soil (pH 6.0–6.5) 

Planting Steps 

1. Dig a hole twice as wide as the root ball. 

2. Mix compost into the removed soil. 

3. Plant at the same depth as it was in the pot (graft just above soil level) . 

4. Water thoroughly with Gardenworks Transplanting Fertilizer 5-15-5 to encourage root development. 

5. Apply mulch to retain moisture and suppress weeds. 

 

Watering Roses 

Roses prefer deep, consistent watering. 

• Water deeply 1–2 times per week (depending on weather). 

• Avoid overhead watering to reduce disease. 

• Water early in the day so foliage dries quickly. 

• Newly planted roses require more frequent watering during establishment. 

In South Coastal BC, increase watering during dry summer periods. 

 

Feeding & Fertilizing Roses 

Roses are heavy feeders and bloom best with regular nutrition. 

• Apply a balanced rose fertilizer in early spring as new growth appears such as Gardenworks Rose Food 6-12-16. 

• Feed again after the first flush of blooms. 

• Stop fertilizing by late summer to allow plants to prepare for winter. 

• Top-dress annually with compost for improved soil health. 

Ask in store about the best fertilizers available at GARDENWORKS for your specific rose type. 

 

Pruning Roses 

Pruning encourages healthy growth and abundant blooms. 

When to Prune in Coastal BC: 
Late February to early March, just as buds begin to swell. 

Basic Pruning Tips 

• Remove dead, damaged, or crossing branches. 

• Cut just above an outward-facing bud. 

• Open the centre of the plant for airflow. 

• Deadhead spent blooms during the growing season to encourage repeat flowering. 

• Hardy Shrub Roses generally do not require much pruning 

Climbing roses require lighter structural pruning — ask us for guidance. 

 

Common Rose Problems & Solutions 

Our coastal climate is ideal for roses, but moisture can increase disease pressure. 

Black Spot 

• Improve air circulation. 

• Remove affected leaves promptly. 

• Avoid overhead watering. 

Powdery Mildew 

• Ensure good sunlight and airflow. 

• Avoid overcrowding. 

Aphids 

• Spray off with water. 

• Use an organic based insect control such as Safer’s End-All  

• Encourage beneficial insects like ladybugs.

Growing Roses in Penticton & the Okanagan 

Gardening conditions in Penticton are significantly different from South Coastal BC. The Okanagan has hotter, drier summers and colder winters, which means rose care requires a few adjustments. 

Climate Considerations 

• Hot, dry summers 

• Lower humidity (fewer fungal disease issues) 

• Colder winter temperatures 

• Greater temperature swings 

 

Sun Exposure in Penticton 

While roses love full sun, extreme afternoon heat can stress some varieties. 

• Full sun is still ideal 

• In very hot, exposed sites, light afternoon shade can reduce stress 

• Ensure consistent watering during heat waves 

 

Watering in the Okanagan 

Roses in Penticton require more frequent watering than coastal locations. 

• Deep water 1–2 times per week during summer 

• During heat waves, monitor soil moisture closely 

• Mulch heavily (2–3 inches) to retain moisture 

• Consider drip irrigation for consistent watering 

Avoid shallow watering — deep soaking encourages strong root systems. 

 

Soil in Penticton 

Many Okanagan soils are sandy or rocky and drain quickly. 

• Incorporate generous amounts of compost when planting 

• Improve water retention with organic matter 

• Monitor soil moisture more frequently than coastal gardens 

 

Winter Protection 

Colder winter temperatures mean extra protection may be needed. 

• Stop fertilizing by late summer 

• In late fall, mound soil or compost around the base of grafted roses 

• Mulch root zones for insulation 

• Avoid fall pruning — wait until early spring 

Hardy shrub roses tend to perform especially well in the Okanagan. 

 

Disease & Pest Differences 

Lower humidity means: 

• Less black spot and fungal disease pressure 

However: 

• Spider mites can be more common in hot, dry conditions 

• Monitor plants during extended dry heat 

 

Best Rose Types for Penticton 

• Hardy shrub roses 

• Landscape roses 

• Many Canadian-bred varieties 

• Heat-tolerant hybrid teas and floribundas
