Sustainable garden design in the UK and Ireland is shifting from “add a few wildlife-friendly plants” to a whole-system approach: build soil, manage water naturally, design for biodiversity, and choose materials that reduce carbon and maintenance. Below are the most important trends we’re seeing right now—plus practical ways to apply them in real gardens.
1. Peat-free is becoming the default (and designers are planning around it)
Peatlands are major carbon stores and wildlife habitats, so the move away from peat is now central to sustainable practice.
Beyond habitat protection, peat extraction releases significant amounts of stored carbon, directly linking soil choice to climate action. For this reason, peat-free specification is increasingly seen as a baseline rather than a niche option.
The RHS continues to push “bogs not bags” and provides detailed guidance on making peat-free composts work well in containers and beds.
In England, the government announced that sales of peat to amateur gardeners would be banned (originally targeted for 2024), which has accelerated consumer awareness even where policy timing has been debated.
How to use this trend in design
-
Specify peat-free growing media at the design stage (especially for container-heavy schemes).
-
Peat-free mixes can behave differently from traditional composts and may require more frequent watering in the first year, until soil structure and biology improve. This should be reflected in irrigation design and maintenance schedules.
-
Build in mulches and moisture management (peat-free can behave differently, so irrigation + mulching choices matter).
-
For clients: position peat-free as a quality choice, not a compromise—better soil biology planning makes gardens more resilient.
2. Biodiversity-first gardens: pollinators, “messy corners,” and living edges
Across both markets, wildlife-friendly gardens are evolving from an aesthetic preference into a set of measurable design features. The focus is shifting towards year-round nectar and pollen sources, layered habitats, and ecological connectivity—turning private gardens into active contributors to local ecosystems rather than isolated green spaces.
-
The RHS highlights practical, high-impact actions like letting some lawn grow longer, planting nectar-rich flowers, and creating ponds.
-
In Ireland, the All-Ireland Pollinator Plan provides clear guidance on pollinator-friendly planting and resources (including planting lists).
How to use this trend in design
-
Design planting in three layers: canopy/small trees, shrubs/hedges, herbaceous/ground layer—then add deadwood/stone/log habitat.
-
Create “nectar continuity”: ensure something is flowering from early spring to late autumn.
-
Use living boundaries (hedges, climbers on fences) to increase habitat and reduce the “sealed box” feeling of urban gardens.
-
Leave autumn leaves in planting beds, install bee hotels, and add bird baths or shallow water sources to support a wider range of species.
3. Rain gardens, SuDS, and “slow the flow” landscapes
With heavier downpours and surface-water flooding risk in many areas, sustainable drainage is now a mainstream garden design topic.
-
Dublin City Council’s SuDS guidance frames sustainable drainage as mimicking natural processes.
-
South Dublin County Council even provides a householder guide that includes designing a rain garden.
-
In the UK, front garden permeability has long been embedded in planning guidance: permeable surfacing can avoid planning permission in many cases.
“Rain gardens and permeable surfaces are a turning point for residential design. Instead of hiding drainage, we now design it as part of the landscape – and clients are starting to see how elegant that can be.” - Renata Ferriera, Garden Design Tutor
How to use this trend in design
-
Replace hard runoff routes with a water journey: roof → water butt → rill/swale → rain garden → soakaway/permeable area.
-
Specify permeable paving and design planting pockets that can take episodic saturation.
-
Turn drainage into a feature: rain gardens can be beautiful, seasonal planting moments, not “engineering.”
4. Meadow lawns and “rewilded” textures (managed wild, not neglect)
Naturalistic planting—meadows, prairie-inspired borders, and relaxed structure—remains popular because it’s both beautiful and ecologically useful. In Irish trend commentary, sustainability and pollinator planting are explicitly called out as key directions.
The RHS also predicts urban spaces (including front gardens) being reimagined for a greener future.
Not all meadows function—or perform—equally, and specifying the right type at design stage is essential:
-
Annual wildflower meadows
Striking, colourful displays created using fast-growing (often non-native) species such as poppies and cornflowers. These are well suited to seasonal schemes, temporary installations or border areas where a short-term visual impact is desired. They require annual re-sowing and higher levels of intervention. -
Perennial grassland meadows
More ecological and long-term in nature, these are dominated by native grasses with wildflowers such as oxeye daisy, knapweed and buttercup woven throughout. Best suited to low-fertility soils, they form permanent, resilient habitats with strong biodiversity value and lower long-term input once established.
How to use this trend in design
-
Replace some lawn with meadow strips (edges, banks, difficult-to-mow areas).
-
Make it legible: add a mown path, crisp edging, or a seating “moment” so it looks designed.
-
Plan maintenance honestly: meadow isn’t “no maintenance,” it’s different maintenance (cut timings, removal of arisings, selective weeding).
5. Climate-resilient planting: drought, wind, salt, and flood tolerance
Designers are increasingly selecting plants for toughness, not just aesthetics, especially for exposed coastal areas, free-draining urban soils, and gardens that swing between wet winters and dry spells.
How to use this trend in design
-
Choose plants that tolerate local stressors (wind/salt near coasts; drought on gravelly soils; saturation in low points).
-
Build resilience with diversity: mixed species planting is less likely to fail catastrophically.
-
Incorporate shade and shelter using small trees/hedges to reduce evapotranspiration and create microclimates.
6. Permeable, low-carbon materials and circular construction
Hard landscaping is a big part of garden footprint. The sustainable shift is toward:
-
Permeable surfaces (better for water + often required/encouraged in front gardens)
-
Reused and reclaimed materials (stone, brick, sleepers—where appropriate and safe)
-
Lower-cement approaches and designs that reduce total hard area
How to use this trend in design
-
Specify reclaimed where possible and design dimensions to suit reused stock.
-
Reduce hard footprint by turning “patio sprawl” into zoned outdoor rooms with planting breaks.
-
Choose materials that weather well and don’t demand harsh chemical cleaning.
7. Wildlife ponds and micro-wetlands are back (even in small gardens)
Ponds are one of the fastest ways to boost biodiversity. The RHS provides clear steps to make ponds more wildlife-friendly.
How to use this trend in design
-
Go shallow at edges: include a beach/shelf for safe access.
-
Avoid fish in wildlife ponds (they can reduce invertebrate life).
-
If space is tight, consider a container pond or mini-bog garden.
-
A “bog garden” in a lined, poorly drained area is an even lower-maintenance option for very small spaces.
8. “Smart sustainability”: tech that supports (not replaces) good design
This is emerging in both markets—more common in higher-end gardens:
-
Drip irrigation and moisture sensors to reduce water waste
-
App-controlled lighting (ideally solar/low-energy)
-
Robotic mowers (worth considering carefully if wildlife is a priority)
How to use this trend in design
-
Make tech optional and modular—good gardens should still function without it.
-
Prioritise efficient irrigation and water storage over decorative gadgets.
“Sustainable garden design isn’t about following a trend – it’s about understanding how a garden actually works as a living system. When designers get the soil, water flow and planting right, sustainability becomes the by-product rather than the goal.”
— Renata Ferriera, Garden Design Tutor

FAQs
What is sustainable garden design?
A design approach that reduces environmental impact while improving resilience and biodiversity—typically through peat-free growing, wildlife habitats, and water-sensitive landscaping.
Do I need planning permission for a new driveway or paved front garden in the UK?
Often not if you use permeable surfacing or direct runoff to a permeable area, but rules depend on the specifics.
What is a rain garden?
A planted depression designed to capture and filter runoff from roofs/paths, helping manage heavy rainfall while adding planting interest. Irish local authorities provide householder SuDS guidance including rain gardens.
How can I make my garden better for pollinators in Ireland?
Prioritise native plants where possible and use pollinator-friendly planting guidance and lists from the All-Ireland Pollinator Plan.
