In Portugal, white stone and gravel are very popular options for low-maintenance gardens. They are cheap, last a long time and need no watering. But are they really the best option? Let's compare them with synthetic grass on the factors that matter most.
Initial and long-term cost
White stone generally has a lower initial cost than synthetic grass. However, over time, stone needs to be topped up (it migrates, sinks and stains) and weeds tend to grow between the stones, requiring regular treatments. Synthetic grass has a higher upfront cost but virtually no maintenance cost over the following 15 years.
Temperature: a critical factor
This is where white stone clearly loses out. On very hot days, white stone and gravel can reach temperatures of 60-70°C — making them unusable in bare feet, dangerous for children and pets. Synthetic grass also warms up, but always stays cooler than stone or concrete.
Comfort and aesthetics
Synthetic grass provides a comfort that stone cannot match: it is pleasant to walk on barefoot, soft for children to play on, and aesthetically much closer to a natural garden. White stone has a more arid look that divides opinion.
Real maintenance of each option
- White stone: requires regular weed treatment, partial top-up after 3-5 years, stain cleaning
- Synthetic grass: occasional brushing, plain water rinse, zero chemical treatments
Impact on property value
Various studies and property market experience confirm that a garden with grass (whether natural or quality synthetic) adds more value to a property than a garden with stone. The green look is universally more appealing to buyers and tenants.
When to choose stone and when to choose synthetic grass
- Choose stone if: you have a very large space where grass costs would be prohibitive, or if the space is purely decorative and never used
- Choose synthetic grass if: you want comfort, aesthetics, safety for children/pets, or if the space is used regularly
Conclusion
For most residential gardens in Portugal, synthetic grass is the superior option to stone or gravel on virtually every criterion that matters: comfort, aesthetics, temperature, safety and property value. Stone only makes sense in specific contexts.
