The smart gardener's winter prep for Surrey & SW London: less work, better results

Snowy scene

As the days shorten and a chill settles over SW London, a quiet, powerful transformation is happening in our gardens. Winter isn't an end; it's a vital period of rest and preparation. For gardens in Kingston, Richmond, and across our region, a smart winter strategy is the gardener's greatest secret to a spectacular spring.

At Flourish Landscaping, we see winter as the season of intelligent investment. It's not about an endless list of chores, but about targeted actions that build resilience, improve our challenging clay soils, and set the stage for a healthier, more beautiful year ahead. Here are our core principles for a winter prep that works smarter, not harder.

1. See the bones: assess your garden’s structure

Winter offers a unique opportunity that no other season can: a clear, unobstructed view of your garden's structure. With herbaceous plants dormant and trees bare, you can truly assess the layout—its strengths and its weaknesses. Take this unique opportunity to stand at your window and ask:

• Does the garden have year-round interest from evergreens, bark, or seed heads?

• Are the pathways creating an elegant journey, or do they feel awkward?

• Is there a need for more permanent structure, like a pergola, an archway, or a small feature tree?

This is the perfect moment to plan the changes—big or small—that will transform your garden next year.

2. Prune with purpose: shaping for future health

With the leaves gone, the true "bones" of your trees and shrubs are revealed. This is the ideal time for structural pruning, a task that pays huge dividends. Focus on removing the "3 Ds"—any wood that is Dead, Diseased, or Damaged. Then, prune out branches that are crossing or rubbing against each other to improve air circulation and prevent future wounds. This is the perfect time for formative pruning on many deciduous trees and fruit trees, as well as tackling overgrown Wisteria and climbing roses to ensure a spectacular floral display.

Crucially, do not prune spring-flowering shrubs like Forsythia or Magnolias now, as you will be cutting off this spring's flowers. Wait until after they have finished flowering to prune them.

3. Feed your soil: the key to taming clay

The heavy clay soils common in Kingston and Surbiton become wet and compacted in winter. The single best thing you can do is to feed them with well-rotted compost or manure. Instead of battling with a spade, apply a thick layer as a mulch over your borders. Over winter, earthworms and microbes will work this organic matter into the soil for you, dramatically improving its structure and drainage without you having to lift a finger.

4. Protect your investments with style

Protecting your less hardy plants and expensive pots from the damaging freeze-thaw cycle is essential.

• Group for warmth: Cluster potted plants together in a sheltered spot, ideally against a house wall, to create a warmer microclimate.

• Insulate with style: Wrap precious terracotta pots in natural hessian or bubble wrap (disguised with an outer layer of hessian) to insulate the roots.

• The m

  ost important Step: Lift ALL pots onto 'pot feet'. This simple action allows excess water to drain away freely, preventing the soil from becoming a waterlogged, frozen block that can kill roots and crack your precious pots.

  
  

5. Don’t neglect the hard landscaping

Winter is the perfect time to give your patios and paths some attention. A thorough clean removes slippery algae build-up, making surfaces safer. Check that drainage channels are clear of leaves and debris to prevent water from pooling near the house. A little maintenance now ensures that as soon as the first spring day arrives, your garden is ready to be enjoyed.

Conclusion

Winter gardening isn't about fighting the cold; it's about a quiet, intelligent partnership with the season. By feeding your soil, making smart cuts, offering thoughtful protection, and taking time to plan, you are making the most powerful investment in your garden’s future. The result is a garden that’s ready for anything, with less work required in the busy spring.
