London gardens are facing a new challenge: increasingly hot, dry periods that can put lawns, plants, trees and outdoor spaces under significant stress. With 2026 already experiencing repeated heatwaves and widespread drought conditions across England, protecting your garden from extreme heat is becoming an increasingly important part of modern landscaping.
For London homeowners, the answer isn’t simply to water everything more. A heat-resilient garden starts with thoughtful garden design, suitable planting, healthy soil, effective landscaping and the right choice of materials.
If you’re looking for ways to protect your garden during hot weather—or want to create a more drought-resistant garden in London—these nine landscaping tips can help.
1. Choose Plants That Can Handle Hotter, Drier Conditions
One of the most effective ways to prepare your garden for heatwaves is to choose plants that are naturally better suited to dry conditions.
Traditional garden plants can struggle when temperatures remain high for prolonged periods. Meanwhile, drought-tolerant plants with features such as silver foliage, deep roots or smaller leaves can often cope better with limited water.
Current gardening advice is increasingly focused on selecting plants that can tolerate hotter, drier summers. London gardens such as those at Fulham Palace are already experimenting with drought-resilient planting schemes.
When planning a new garden, consider plants such as lavender, salvias, ornamental grasses and other drought-tolerant varieties.
A professional garden design service in London can help you select planting that suits your garden’s soil, aspect, available sunlight and long-term maintenance requirements.
2. Improve Your Soil Before the Next Heatwave
Healthy soil is one of your garden’s best defences against extreme weather.
Poor-quality or compacted soil can struggle to absorb and retain moisture. Improving soil structure with appropriate organic matter can help plants develop stronger root systems and make better use of available water.
Mulching is particularly useful during hot weather. A layer of suitable organic mulch can reduce evaporation from the soil, suppress weeds competing for moisture and help protect plant roots from temperature fluctuations. The RHS specifically recommends mulching plants to help retain moisture during heatwaves and drought.
For a new landscaping project, proper soil preparation should therefore be considered alongside planting rather than treated as an afterthought.
3. Don’t Panic-Water Your Lawn
One of the most common reactions to a heatwave is to try to keep the lawn perfectly green.
However, a brown lawn doesn’t necessarily mean that the grass is dead. During prolonged dry conditions, lawns can become dormant and recover when temperatures fall and rainfall returns.
The RHS advises against excessive lawn watering during drought and recommends reducing wear on stressed grass.
If maintaining a green lawn throughout the year is important to you, artificial grass can provide an alternative that doesn’t require regular watering or mowing.
Groundteam installs artificial grass as part of wider landscaping services in London, creating practical, low-maintenance garden areas for busy households.
4. Water Strategically Rather Than Constantly
When watering is necessary, the goal should be to make every drop count.
Frequent, shallow watering can encourage roots to remain close to the soil surface, where they are more vulnerable to drying out. Deeper watering can encourage plants to develop stronger root systems.
The timing also matters. Watering during the hottest part of the day can result in significant evaporation before plants can make full use of the moisture.
During periods of water restrictions, always follow the requirements of your local water company. The RHS also advises gardeners to follow hosepipe restrictions where they apply.
For London homeowners, planning water use before temperatures rise can make a significant difference.
5. Create More Shade
Strategic shade can protect plants, seating areas and soil from the most intense afternoon heat.
This doesn’t necessarily mean covering your entire garden. Instead, consider creating shaded zones using landscaping features such as pergolas, arbours, trees and carefully positioned planting.
A pergola can provide a useful focal point while creating a comfortable outdoor seating area. Climbing plants can also be trained over the structure, creating additional natural shade as they mature.
Groundteam has experience incorporating pergolas, arbours and arches into garden layouts, helping London homeowners create attractive and functional outdoor spaces.
6. Use Hard Landscaping to Reduce Maintenance
A heatwave can highlight how much maintenance your garden requires.
Large areas of thirsty lawn, numerous delicate planting beds and poorly chosen surfaces can all increase the amount of work required during hot weather.
A professionally designed garden can combine planted areas with durable landscaping features such as pathways, patios, decorative aggregate, retaining walls and artificial grass.
This creates a balance between greenery and practical outdoor surfaces without making the garden feel sterile.
For London properties where space is limited, good landscape design can also help make every section of the garden more functional.
7. Protect New Plants During Extreme Heat
Newly planted trees, shrubs and flowers are generally more vulnerable to heat stress because their root systems haven’t become fully established.
If you’re planning a garden renovation during particularly hot conditions, timing matters.
The RHS advises caution about planting during peak drought conditions, particularly when the soil is extremely dry.
Where possible, major planting projects should be planned around suitable weather conditions rather than simply choosing the hottest part of summer.
A professional London landscaping company can help you determine which work should be completed immediately and which elements are better scheduled for cooler conditions.
8. Think About Drainage as Well as Drought
It might seem strange to discuss drainage when the immediate problem is extreme heat, but London’s weather can swing rapidly between prolonged dry periods and intense rainfall.
A garden that becomes extremely dry can also develop compacted or hardened soil, making it more difficult for heavy rainfall to penetrate effectively.
This is why climate-resilient landscaping should consider both extremes.
Groundwork, drainage channels, suitable soil preparation and carefully designed levels can help manage water more effectively when rainfall eventually arrives.
This is particularly important for London gardens with slopes, lower-level areas or existing waterlogging problems.
9. Design Your Garden for the Future
Perhaps the most important landscaping tip is to stop designing gardens purely for today’s climate.
The increasing frequency of extreme heat is encouraging homeowners, gardeners and professional landscapers to rethink planting and garden design. London’s parks and gardens are already experimenting with more drought-resistant planting and water-saving techniques in response to changing conditions.
A future-focused garden could include:
- Drought-tolerant planting
- Improved soil preparation
- Mulched flowerbeds
- Efficient water management
- Areas of shade
- Low-maintenance surfaces
- Suitable drainage
- Durable landscaping materials
The objective isn’t to remove plants or turn your garden into a completely hard-landscaped space. Instead, it is about creating a garden that is better equipped to cope with changing conditions.
