Harvesting & Soil Preparation — December Tasks for Your Edible Garden in the Pacific Northwest
Even though the days are shorter and cooler in December, your edible garden in the Pacific Northwest still has worthwhile tasks. This month is ideal for harvesting, protecting crops, and prepping soil so you’ll be ahead when the new growing season starts.
- Harvest and Protect Winter Greens
- Vegetables like kale, collards, Brussels sprouts, cabbage, and winter chard can still be productive this month. Harvest what’s ready and enjoy being outdoors even in cooler weather.
- Mulch generously around these crops to protect roots from freeze-thaw cycles and to preserve soil moisture through winter.
- Bare-Root Planting & Dormant Transplants
- December can be a good time to plant trees and shrubs if the soil is not frozen or overly saturated.
- Consider bare-root fruit trees, berry canes, shrubs, or vines so roots can establish while top-growth remains dormant.
- When planting now, choose a well-drained site and mulch the root zone to suppress weeds and retain moisture.
- Soil Amendment & Bed Preparation
Get a jump on spring by improving your soil now:
- Apply 2–4 inches of compost or well-rotted manure to garden beds. Winter rains will help integrate nutrients into the soil.
- Remove deep-rooted perennial weeds so they don’t re-emerge in spring.
- For areas you won’t plant until later, apply mulch or wood chips to suppress weeds and protect soil structure.
- Start Planning & Protect Vulnerable Plants
- Order seeds, starts, or bare-root stock early before spring demand peaks.
- Watch for vole or rodent damage around root crops or young plants—mulch helps, but some areas may need protection.
- Shelter tender crops or potted edibles during freezing nights.
- Minimal Maintenance, Maximum Return
- Clean up spent plants where needed, but don’t over-tidy—leaving some organic matter protects soil and provides habitat.
- Avoid stepping on saturated beds to prevent compaction.
- Use the downtime to review garden notes and plan crop rotation or bed improvements for spring.
Takeaway: December isn’t a dormant period for the edible garden—it’s a chance to nourish and prepare. With winter greens harvested, compost applied, and next year’s plans underway, you’re giving your garden a healthy head start for spring.
