Seasonal Maintenance Guide
Spring
- Cut back prairie grasses to 6 inches in late April or early May
- Remove winter-damaged foliage once new growth emerges
- Check drainage systems after spring snowmelt for proper function
- Apply 2 inches of shredded bark mulch to planting beds
- Divide coneflowers and other perennials every 3-4 years if overcrowded
Summer
- Water new plantings weekly during establishment year
- Established native plants rarely need supplemental irrigation
- Deadhead coneflowers if desired, or leave for seed heads
- Monitor for Japanese beetles on susceptible plants
- Weed minimally as native plants establish and outcompete weeds
Fall
- Plant new trees and shrubs by late September for winter establishment
- Leave all ornamental grass plumes intact for winter interest and wildlife
- Cut back perennials only if diseased; otherwise leave for structure
- Apply slow-release fertilizer to evergreens in early fall
- Drain and winterize irrigation systems before first hard freeze
Winter
- Allow natural snow to insulate dormant plants
- Gently brush heavy wet snow off evergreens to prevent breakage
- Avoid walking on frozen grass or planting beds
- Use pet-safe ice melt near plants (avoid sodium chloride)
- Enjoy winter structure of grasses, seed heads, and white birch bark
