Dealing With a Waterlogged Garden
Why Gardens Flood
- Heavy clay soil that does not drain well
- High water table
- Runoff from neighbouring properties or roads
- Blocked or broken land drains
- Compacted soil from foot traffic or construction
Drainage Solutions
- French drains: Gravel-filled trenches with perforated pipe directing water to a soakaway
- Soakaways: Underground chambers that allow water to slowly soak into the ground
- Land drains: Perforated pipes laid in a herringbone pattern beneath the lawn
- Raised beds: Elevate planting areas above the waterlogged ground
- Gravel areas: Replace hard paving with permeable gravel
SuDS for Gardens
- Rain gardens: Shallow, planted depressions that collect roof and patio runoff
- Water butts: Collect rainwater for garden use
- Permeable paving: Replace concrete patios with permeable alternatives
- Green roofs on sheds/garages: Absorb rainfall at source
- Wildlife ponds: Attractive water storage that supports biodiversity
Planting for Wet Gardens
- Trees: Willow, alder, birch, swamp cypress
- Shrubs: Dogwood, elderberry, guelder rose
- Perennials: Iris, astilbe, ligularia, marsh marigold
- Grasses: Miscanthus, reed canary grass
