From Food Waste to Roadways: Using Compost to Improve Soil Conditions and Tree Success Along Highways

Planting trees along highway roadsides is a good way to increase tree coverage in cities, but getting trees to grow here and maintaining these plantings over time can be difficult. Reducing soil compaction and adding organic material, such as compost, can improve roadside soils and support tree growth in these areas.
