December Gardening Chores
Planting
- Plant bare-root trees and shrubs (if the ground is not frozen).
- Plant spring-flowering bulbs (if not done in fall and the ground is still workable).
- Sow seeds indoors for crops that need a long growing season (e.g., onions, early spring flowers).
Maintenance
- Continue to water evergreen plants, especially if the weather is dry.
- Apply a fresh layer of mulch around plants for insulation against cold temperatures.
- Protect sensitive plants from frost by covering them with row covers or blankets.
- Drain and store hoses and turn off outdoor water spigots to prevent freezing.
- Clean and sharpen garden tools before putting them away for winter.
- Check stored tubers, bulbs, and corms (like dahlias and gladiolus) for mold or rot.
- Ensure good air circulation for plants in cold frames or greenhouses.
Harvesting
- Harvest cold-tolerant crops such as kale, collards, and Brussels sprouts.
- Continue to harvest winter herbs that can tolerate the cold.
Planning
- Review seed and plant catalogs for new varieties to try next spring.
- Order seeds and gardening supplies early for the best selection.
- Draw up next year’s garden plan, rotating crops and planning new beds.
- Take soil samples for testing to prepare for spring amendments.
