Seasonal Maintenance Guide
- Cut back ornamental grasses to 4-6 inches in late April or early May
- Remove winter-damaged foliage once new growth appears
- Apply compost to planting beds to maintain soil acidity
- Check drainage systems after spring melt for proper function
- Divide hostas and grasses every 3-4 years in late spring
- Water new plantings during dry spells; established plants rarely need supplemental water
- Remove fern fronds that brown in extreme heat or drought
- Deadhead hosta flowers if desired for cleaner appearance
- Monitor for slugs on hostas and handpick in early morning
- Trim grass seed heads in late summer if ultra-clean look desired
- Plant new trees and shrubs by late September for winter establishment
- Leave ornamental grass plumes intact for winter interest and wildlife
- Cut back perennials only if diseased; otherwise leave for structure
- Apply 2-3 inches of shredded bark mulch around plants
- Drain and winterize irrigation systems before first hard freeze
- Allow natural snow to insulate dormant plants
- Gently brush heavy snow off evergreens to prevent breakage
- Avoid walking on frozen grass or planting beds
- Use calcium chloride ice melt near plants (avoid sodium chloride)
- Enjoy winter structure of grasses, seed heads, and bark
