Professional Tree Care in Chicago, Illinois
Chicago maintains one of the largest urban forests in the United States, with an estimated 3.6 million trees across its neighborhoods and parks. The city's tree canopy includes mature honeylocusts, lindens, London planetrees, and elms lining its iconic boulevards, along with diverse species in Lincoln Park, Jackson Park, and residential neighborhoods.
Top Tree Health Threats in Chicago
Emerald ash borer has removed tens of thousands of ash trees from Chicago's streets and parks. The city's replanting program has diversified the canopy, but the loss of ash canopy has significantly changed many neighborhoods.
Asian longhorned beetle (ALB) was detected and eradicated from a Chicago neighborhood in 1998, but continued vigilance is important. Dutch elm disease remains active, though disease-resistant cultivars are now widely planted. Bacterial leaf scorch affects oaks and elms, causing progressive canopy decline.
Gypsy moth (spongy moth) outbreaks periodically defoliate oaks and other hardwoods. The city's dense development creates urban heat island effects that stress trees, making them more vulnerable to pests and diseases.
Climate & Seasonal Care
Chicago is in USDA Hardiness Zone 6a, with lake effect moderating temperatures near the lakefront (effectively Zone 6b). Harsh winters with heavy snowfall and ice, combined with summer heat and drought, create challenging growing conditions. Street trees face additional stresses from road salt, compacted soils, and limited root space.
