Choosing sustainable garden furniture is about more than just appearance. In the UK, where the climate can vary dramatically throughout the year, selecting the right type of wood for your outdoor furniture makes all the difference in longevity, appearance, and environmental impact. From teak to eucalyptus, this guide explores the most suitable wood options for outdoor use, focusing on sustainability, durability, and maintenance.
Why Wood Durability Matters Outdoors
Exposure to elements
Outdoor furniture faces daily exposure to weather conditions such as rain, wind, and UV rays. Over time, these elements can cause wood to crack, fade, or warp if it’s not strong or properly treated.
Weather, pests, and decay
In addition to the weather, garden furniture in the UK must also resist pests like woodworm and natural decay caused by moisture. Choosing hardwoods with natural oils can offer better protection against these challenges.
Impact on long-term cost and aesthetics
Investing in more durable wood upfront often pays off over time. It reduces the need for frequent replacements and helps maintain a beautiful, natural look without constant upkeep.
Teak – The Gold Standard for Outdoor Durability
Natural oils and weather resistance
Teak is widely regarded as the best wood for outdoor furniture thanks to its high oil content, which naturally repels water and resists rot, insects, and fungal decay. This makes it particularly suited for the damp and variable UK climate.
Lifespan with minimal maintenance
Teak can last over 25 years when left untreated, though it does benefit from occasional cleaning. Over time, it develops a silvery-grey patina, which many people find attractive.
High-end price point
While teak is more expensive than other options, its combination of low maintenance and long lifespan makes it a sound long-term investment, especially if you’re looking for sustainable outdoor furniture with lasting value.
Eucalyptus – Affordable and Strong
Dense hardwood
Eucalyptus is a fast-growing hardwood, making it a more sustainable and budget-friendly alternative to teak. It has natural resistance to rot and insects, although it’s slightly less durable overall.
Requires annual treatment
To extend its lifespan, eucalyptus should be treated yearly with oil or sealant. This helps it maintain its appearance and resist the effects of the UK’s wet winters and humid summers.
Mid-range pricing with decent longevity
For those seeking eco-friendly garden furniture without the premium cost of teak, eucalyptus offers a practical middle ground. When well maintained, it can last for 10 to 15 years.
Acacia – Beautiful and Budget-Friendly
Popular for aesthetics
Acacia wood is known for its rich grain patterns and warm tones. It’s often used for garden tables, benches, and chairs due to its attractive appearance and availability.
Susceptible to moisture if untreated
Without regular sealing, acacia is prone to absorbing moisture, which can lead to cracking or swelling. In the UK’s often damp weather, protective finishes are essential.
Moderate maintenance needed
Annual oiling and proper storage during winter months can help acacia furniture remain functional and appealing for years. It's best used in partially sheltered outdoor areas for optimal longevity.
Softwoods – Least Durable for Outdoor Use
Examples: pine, cedar
Softwoods like pine and cedar are more affordable but generally less suitable for long-term outdoor use. Cedar performs better than pine due to its natural oils but still lacks the toughness of hardwoods.
Needs pressure treatment or sealant
Pine furniture must be pressure-treated or sealed to survive outside. Even then, it’s likely to degrade faster than hardwoods, especially in wetter areas.
Best for short-term use or covered areas
Softwood garden furniture is a cost-effective choice for temporary setups or covered patios. However, it won’t withstand continuous exposure to the elements without considerable care.
How to Maximise the Lifespan of Wooden Garden Furniture
Apply sealants/oils annually
Using a suitable oil or wood sealant helps protect against moisture and UV damage. This step is especially important for woods like acacia and eucalyptus.
Use furniture covers
Waterproof covers can significantly extend the life of your furniture by shielding it from rain and snow. Ensure the cover is breathable to prevent mildew.
Store during winter
Whenever possible, move your garden furniture into a shed or garage during the colder months. Even the most durable hardwoods benefit from dry storage during winter.
Cleaning and sanding tips
Gently clean your furniture with soapy water and a soft brush. Light sanding before re-oiling can help maintain the wood’s smooth finish and prevent surface wear.
FSC Certification and Sustainability
Ethically sourced timber
When buying wooden outdoor furniture, look for FSC-certified products. The Forest Stewardship Council (FSC) ensures that the wood comes from responsibly managed forests.
Environmental benefits
FSC-certified wood supports sustainable forestry practices, protects wildlife habitats, and promotes ethical labour conditions. Choosing certified wood helps reduce the environmental impact of your furniture. You may also wish to explore Eco-Friendly and Upcycled Furniture for more creative, sustainable alternatives to traditional garden pieces.
Why FSC-certified wood matters
Opting for FSC timber means you’re not only investing in high-quality garden furniture but also contributing to global efforts to preserve natural ecosystems. It’s a simple way to make a positive difference.
Lazy Susan’s Recommendation
Summary of wood choices
Teak stands out for its durability, low maintenance, and timeless look. Eucalyptus and acacia are both excellent alternatives, offering style and strength with some upkeep. Softwoods are best for temporary or protected areas.
Best value options
For UK buyers, eucalyptus represents the best balance between sustainability, affordability, and lifespan. Acacia is ideal for smaller budgets where some maintenance is acceptable.
Why teak leads in durability
Teak’s ability to withstand the elements with minimal effort makes it Lazy Susan’s top recommendation for those seeking long-lasting, sustainable garden furniture that retains its charm for decades.
FAQs
What is the most weather-resistant wood for outdoors?
Teak is the most weather-resistant option due to its natural oils that repel water, resist decay, and prevent insect damage.
Does teak furniture need to be treated?
Teak does not require treatment, but applying oil can help preserve its golden colour. Untreated teak naturally ages to a silver-grey finish.
Is eucalyptus better than acacia?
Eucalyptus is generally more durable and weather-resistant than acacia, although both are hardwoods suitable for outdoor use with proper care.
How can I maintain wooden garden furniture?
Clean regularly with mild soap and water, apply oil or sealant annually, use protective covers, and store furniture indoors during the winter months.
Choosing sustainable garden furniture means selecting wood that not only fits your style and budget but also supports long-term environmental goals. By understanding the strengths of different woods—teak, eucalyptus, acacia, or even pressure-treated softwoods—you can make a well-informed choice that serves your garden and the planet for years to come.
