December is the garden’s rest month — and the gardener’s too. Most of the work is done, the soil is mulched, and tools are in order. This isn’t a time for passive waiting, but for planning, learning, and a few small but important winter tasks.
Is there anything to do in the December garden?
Less than any other time of year — but yes, there is. Mainly observation, care, and planning.
- ❄️ Check frost-tolerant crops: kale, leeks, winter lettuce — protect with fleece if needed
- 🐦 Fill bird feeders: winter birds will be valuable allies against pests next summer
- 🌱 Germination testing: if you sprout seeds indoors in winter (e.g. microgreens), this is a great winter activity
- 🪴 Container plants: protect frost-sensitive potted plants or bring them under cover
Plan for next season
December is the best month to plan the coming year — this year’s experience is still fresh, and there’s time to think through changes.
- 📋 What goes where next year? Crop rotation decisions made now mean the right plant in the right place come spring
- 🌱 What new species or varieties would you try? December is the time to browse seed catalogues
- 💧 Is there anything to improve in the irrigation setup or bed layout?
Sort your seed collection
If you collected seeds during the season (beans, peas, lettuce, tomato), December is a good moment to reorganise, label, and germination-test them.
- 🏷️ Label every seed with variety and year
- 🧪 Germination test: lay 10 seeds on damp paper towel — in a week you’ll know the germination rate
- 📦 Store cool, dark, dry — a well-sealed glass jar or paper envelope is better than plastic
Rest — but don’t forget next spring
The gardener deserves winter too. December is the month of balance: rest, but keep a small connection with the garden — review this year’s notes, plan, and if you need inspiration, a moon calendar can even help you think through the winter sowing rhythm.
Summary
December is the well-deserved rest month for garden and gardener alike — but not one of complete inactivity. Monitoring frost-tolerant crops, filling bird feeders, sorting the seed collection, and planning next year can all be done without standing outside in the cold. Plan well in December, and spring will start with intention and preparation.
❓ Frequently Asked Questions
Why do winter bird feeders help against next summer’s pests? Winter birds that stay near a feeding site keep foraging there year-round, and from spring onward they hunt insects, larvae, and eggs in the garden — a significant share of an overwintering pest population gets eaten before it can multiply, so winter feeding builds a long-term, natural biological defense.
Why does the germination test work on a damp paper towel? A seed needs moisture, oxygen, and the right temperature to germinate — the damp towel supplies water that activates the seed’s enzymes, while the paper’s porous structure lets enough air through; within a week, the germination rate reliably shows how much viable seed is in the batch.
Why is it better to store seeds in glass or paper rather than plastic? Plastic seals airtight but doesn’t regulate humidity — if a seed goes in slightly damp, the trapped moisture can trigger mold, while glass or a breathable paper bag lets moisture equalize more evenly.
Why does row cover help frost-tolerant plants if the fabric itself doesn’t heat anything? Row cover traps a thin layer of air between the plant and the open air, reducing heat loss and dampening overnight radiative cooling — heat absorbed from the soil during the day stays around the plant longer, softening the overnight minimum by a few degrees, which can be enough to avoid frost damage in an already frost-tolerant species.
