Sundancer Poplar

Populus x canadensis 'Sundancer'

Sundancer Poplar is a fast-growing, columnar hybrid poplar that is well-suited to prairie landscapes. It is highly cold-hardy (Zone 2), drought-tolerant, and disease-resistant, making it a great choice for windbreaks, shelterbelts, or as a vertical accent tree. Unlike some poplars, it has stronger wood, fewer suckers, and less aggressive roots, making it a better option for urban and residential plantings.

Planting & Location

• Hardiness Zone: 2-6 (ideal for Southwest Saskatchewan)
• Mature Size: 40-50 feet tall, 10-15 feet wide
• Growth Rate: Fast (3-6 feet per year under ideal conditions)
• Sunlight Needs: Full sun (at least 6 hours of direct light per day)
• Soil Preference:
  • Adaptable to a wide range of soils (loam, clay, sandy).
  • Prefers moist, well-drained soil but tolerates some dryness.
  • Can handle alkaline and slightly acidic soils.
• Spacing: 10-12 feet apart for a hedge or windbreak, 15+ feet apart for individual plantings.

Watering

• Young Trees (First 2-3 Years): Deep water 1-2 times per week to help root establishment.
• Established Trees: Drought-tolerant, but benefits from deep watering every 2-3 weeks in hot, dry weather.
• Avoid Overwatering: Poplars don’t like soggy roots—ensure proper drainage.

Fertilizing

• First Year: No fertilizer needed—focus on root growth.
• Mature Trees:
  • Apply a balanced slow-release fertilizer (10-10-10) in early spring to boost growth.
  • Organic options: Compost or well-rotted manure in spring as mulch.

Pruning & Maintenance

• Best Time to Prune: Late winter to early spring before new growth starts.
• How to Prune:
  • Remove dead, damaged, or crossing branches for a strong structure.
  • Maintain a single central leader for a strong, upright form.
  • Minimal pruning needed—this poplar maintains its shape naturally.
• Suckering: Less suckering than other poplars, but remove any that appear.

Pest & Disease Management

Common Pests:

• Aphids – Can cause curled leaves and sticky honeydew.
  • Solution: Encourage natural predators (ladybugs) or spray with insecticidal soap.
• Leaf Beetles – Can chew leaves in summer.
  • Solution: Handpick or use insecticidal soap if severe.

Common Diseases:

• Canker Diseases (e.g., Cytospora Canker) – Can cause branch dieback.
  • Solution: Prune out affected branches and ensure proper watering.
• Rust (Melampsora spp.) – Causes orange spores on leaves.
  • Solution: Rake and remove fallen leaves; apply fungicide if severe.
• Leaf Spot (Marssonina spp.) – Causes small black spots on leaves.
  • Solution: Improve air circulation and remove infected leaves.

Winter Protection

• Young Trees: Protect trunks with tree wrap or guards to prevent sunscald and frost cracks.
• Mulching: Apply 2-4 inches of mulch around the base (but not touching the trunk) to insulate roots.
• Deer & Rodent Protection: Use tree guards if browsing is an issue.

Landscape Uses

Fast-growing windbreak or shelterbelt
Great privacy screen with narrow, upright form
Cold-hardy & drought-resistant once established
Less aggressive roots & minimal suckering compared to other poplars
Strong wood—less prone to breakage than other hybrid poplars
Low-maintenance

Additional Notes:

• Sundancer Poplar is a superior hybrid poplar compared to traditional poplars due to its disease resistance, strong structure, and non-invasive root system.
• It is an excellent choice for prairie conditions, where wind and drought can be challenging for other trees.
• Lifespan: 30-50 years—longer than most fast-growing poplars.
