Essential Winter Garden Care in South East London: What to Do in December

Updated: Mar 9

December is a quieter month in the garden, but it’s also one of the most important for long-term plant health. The work you do now protects your outdoor space through winter and sets the stage for strong spring growth. As a South East London gardener, here are the key winter garden care tasks I recommend.


1. Protect Plants from Frost


Cold snaps can damage even hardy plants. Use fleece, mulch, or straw around the base of tender shrubs. Raise pots off the ground to help drainage and prevent roots from freezing. If you have palms, tree ferns, or exotics, make sure their crowns are wrapped and protected. Proper frost protection is essential for gardens in South East London and Kent.



2. Tidy Beds and Borders


Clearing dead growth and fallen leaves prevents pests and diseases from overwintering in your borders. Cut back faded herbaceous plants, remove annuals, and finish with mulch to insulate the soil. This simple task is the backbone of effective garden maintenance in December.



3. Light Winter Pruning

December is a great time to shape evergreens and remove dead, diseased, or crossing branches. Proper pruning improves airflow and sets up healthier spring growth. For larger shrubs or trees, professional tree care ensures everything is cut safely and correctly.



4. Care for Your Lawn

A well-kept winter lawn leads to a strong spring lawn. Key December tasks include:

  • Keeping grass clear of leaves

  • Avoiding foot traffic when frozen or waterlogged

  • Light aeration of compacted areas

  • Brushing away moss and debris


If your lawn suffers from standing water, deeper lawn drainage work may be needed — winter is the ideal time to fix this.



5. Check Your Garden for Winter Safety

Storms and strong winds highlight weak branches, leaning fences, and unstable structures. A quick safety check now can prevent damage later. If anything looks unsafe — especially trees or large shrubs — it’s worth getting a professional assessment.



6. Plan Ahead for Spring

December is one of the best months to plan bigger garden projects such as:

  • New planting schemes

  • Turfing or re-turfing

  • Raised beds

  • Complete garden redesigns

  • Seasonal garden clearance


Booking early ensures your garden is ready for the spring rush.



7. The Importance of Soil Health

Soil health is crucial for a thriving garden. In December, take time to assess your soil. Test its pH and nutrient levels. Adding organic matter can improve soil structure and fertility. This will benefit your plants in the coming seasons.


8. Winter Wildlife Care

Winter is tough for wildlife. Consider putting out bird feeders and water sources. This not only helps local birds but also adds life to your garden during the colder months. A thriving ecosystem can enhance your garden's health.


9. Mulching Benefits

Mulching is a great way to protect your garden during winter. It helps retain moisture, suppress weeds, and regulate soil temperature. Choose organic materials like bark or straw. This will break down over time, enriching your soil.
