Ragosa Rose in Zone 5: Hardy with Fungus Watch

A zone 5 gardener asks if Ragosa rose survives, pest issues, and sun tolerance.

Yes, It's Hardy

Ragosa (Rosa rugosa) is very hardy to zone 3. Full sun is ideal.

Common Issue: Fungal Leaf Spot

Wet years cause yellow leaves with black spots. Treat:

• Remove affected leaves.
• Spray fungicide every 10 days until controlled.
• Improve air circulation.

Bonus

Rugosa roses have fragrant flowers, large hips (vitamin C), and attractive fall foliage. Very low maintenance once established.
