10 Essential Tasks for Expert Gardeners: December gardening jobs are all about quiet efficiency – the kind that keeps your mature garden resilient through winter and ready for spring. With just 7–8 hours of daylight, average temps of 2–7°C and 80–100mm of rain, the focus is on protection, planning and subtle renewal. These 10 tasks are field-tested by gardeners in their 40s–60s who know that December is less about doing and more about doing it right.
Sharpen and Oil Tools
Rust sets in fast in damp December air. Clean secateurs, loppers and spades with warm soapy water, then wipe metal with Organic Neem Oil (£16.50). It prevents corrosion and keeps blades slick for clean cuts come spring.
Fleece Tender Plants
Borderline hardy plants like agapanthus and cordyline need insulation. Wrap crowns with Eco-Friendly Garden Fleece – secure loosely with twine to allow airflow. Check weekly on mild days to prevent rot.
Mulch Beds and Borders
A 5–7cm layer of mulch locks in moisture and shields roots from freeze-thaw cycles. Use Coir Mulch Mats around perennials and shrubs – they suppress weeds and break down slowly into the soil.
Force Bulbs for Christmas
Hyacinths, paperwhites and amaryllis bring scent and colour indoors. Plant prepared hyacinths in Coir Pots with Peat-Free Compost. Keep in a cool, dark spot (8–10°C) for 10 weeks, then move to light – blooms by Christmas.
Feed the Birds
Winter is tough on wildlife. Hang Natural Suet Feeders filled with high-energy fat balls. Position near cover but away from windows to avoid collisions.
Compost Festive Kitchen Waste
Peels, cores and cardboard don’t belong in landfill. Add them to your heap and speed breakdown with Compost Plus – microbial boost turns waste into gold by spring.
Test and Plan Soil Nutrition
December is audit season. Take samples from key beds and test with a Soil Testing Kit. Use results to plan 2026 rotations – follow brassicas with legumes, not nightshades.
Prune Dormant Fruit Trees
Apples and pears can take light pruning now. Remove dead, diseased, or crossing branches with clean, sharp Eco-Friendly Secateurs. Avoid heavy cuts – save shaping for summer.
Treat Timber Structures
Gales and wet weather rot wood fast. Brush LifeTime Wood Treatment onto fences, pergolas and shed doors. One coat now lasts years.
Journal Your Garden’s Year
The most underrated of December gardening jobs. Log what worked, what failed and what you’ll change. Sketch next year’s layout. Include pest patterns, yield notes and one bold rewilding goal – like a new Wildflower Seed Mix edge.
