Garden Maintenance Checklist Before 2026

Start the New Year with a Healthy, Organized Garden

As 2025 draws to a close, it's the perfect time to give your garden the attention it needs to thrive in the coming year. A comprehensive end-of-year maintenance routine ensures your plants stay healthy through winter and are ready to burst into life when spring arrives. This checklist will help you tackle essential tasks before 2026, setting your garden up for success in the new year.

Why Year-End Garden Maintenance Matters

Taking time for garden maintenance before the new year offers multiple benefits:

• Prevents winter damage: Proper preparation protects plants from harsh weather
• Reduces spring workload: Tasks completed now mean less to do when growing season begins
• Improves plant health: Clean, well-maintained gardens have fewer pest and disease issues
• Extends tool life: Proper cleaning and storage prevents rust and damage
• Provides planning time: Assess what worked and what didn't for better planning
• Fresh start: Begin the new year with an organized, ready-to-grow garden
