Seasonal Maintenance Guide
- Remove winter protection from roses in late April
- Cut back perennials when new growth appears (late April-May)
- Divide overcrowded perennials like asters and bee balm
- Apply compost and organic fertilizer after soil thaws
- Stake delphiniums and tall perennials before growth accelerates
- Plant summer annuals after Memorial Day (last frost)
- Deadhead roses, delphiniums, and repeat bloomers regularly
- Water deeply during dry spells, especially new plantings
- Monitor for powdery mildew on bee balm, provide air circulation
- Cut back early bloomers like hardy geraniums for rebloom
- Harvest flowers for bouquets to encourage continued flowering
- Watch for Japanese beetles on roses, handpick early morning
- Continue deadheading through September for extended blooms
- Plant spring bulbs in October before ground freezes
- Leave perennial seed heads for winter interest and birds
- Apply mulch after ground freezes to prevent frost heaving
- Cut back disease-prone plants, leave structural perennials standing
- Protect roses with mulch mounds in late November
- Brush heavy snow from evergreens and rose canes
- Monitor rose protection, add mulch if exposed during thaws
- Plan next season improvements and order plants
