Is it time to plant some new trees? Plant them at least three feet away from paved surfaces. If the spaces between the sidewalks are smaller than 3-4 feet, try to plant trees no greater than 30 feet when you’re an adult. Try to leave an area of at least 8 feet or more between sidewalks for trees 50 feet or larger. Root barriers, such as plastic or woven geotextile fabric, should be installed. Roots will be driven deeper into the earth and away from the path as a result of this. see page

Trimming roots should be done with extreme caution. Larger roots maintain the tree and offer critical water and nutrients, so don’t cut roots that are more than 2 inches in diameter. Cut away from the trunk as much as possible. Cleanly cut and mulch well. Remember that roots both support the trunk and give the tree with the nutrition it requires. Cutting the tree’s roots can make it more susceptible to wind damage, and it can even kill elder trees in three to five years.
Consider curved walkways if you’re worried about severing roots and the tree is in good shape. Make sure there’s enough space around the trunk and roots. If the tree is in bad shape, you may want to consider removing it and replacing the sidewalk.
Grinding the elevated edge down to level for modest sidewalk displacement of an inch is an option. Patching the sidewalk using a cement wedge can help with bigger displacement. Remove a section of the sidewalk, re-pour the concrete, and build a bridge over the roots is another option to explore. It’s sometimes advisable to simply replace the entire sidewalk with different materials. Concrete is more expensive and less flexible than asphalt. While more appealing and pricier, landscape pavers are still susceptible to root damage but are easier to modify and level. Rubber sidewalks are a novel, environmentally friendly option created from recycled tyres that are both permeable and flexible.
