The Best and Worst Time to Plant in Chicago: A Seasonal Guide

When it comes to planting in the Chicago area, timing is everything. The Midwest’s shifting seasons — with their temperature extremes, unpredictable frosts, and bursts of humidity — can be both a blessing and a challenge for homeowners looking to enhance their landscapes. At Skyline Exteriors Landscaping, we believe that successful planting starts with understanding when to plant, not just what to plant.

In this post, we’ll walk you through the best and worst times to plant in Western Chicago, along with some expert tips to help you make the most of your outdoor investment.

🌿 Best Times to Plant in Chicago

Spring (Mid-April to Early June)

Why it works:After a long winter, spring offers fresh opportunities. Once the soil warms and the danger of hard frost has passed — usually around mid-April — conditions are ideal for planting most types of flowers, shrubs, vegetables, and trees. The days grow longer, the sun returns, and moisture levels remain relatively high, all of which create a nurturing environment for new roots.

Best plants for spring:

• Perennials like daylilies, coneflowers, and hostas

• Cool-season vegetables such as lettuce, peas, and spinach

• Deciduous shrubs and ornamental trees

• Lawn seed and sod

Tip:Don’t be tempted by the first warm day in March. Early spring weather in Chicago is notoriously fickle. Always check the soil temperature (ideally above 50°F) and avoid planting in waterlogged soil to prevent root rot.

Fall (Mid-September to Late October)

Why it works:Fall may not get the same hype as spring, but it’s one of the most underutilized planting seasons. The cooler air temperatures are easier on young plants, while the soil remains warm enough to encourage root growth before winter dormancy. Less evaporation also means your new plants require less watering.

Best plants for fall:

• Spring-flowering bulbs like tulips, daffodils, and crocus

• Hardy perennials and ornamental grasses

• Trees and shrubs, especially those that are native or well-adapted to the region

• Cool-season turf grass

Tip:The planting window closes quickly once overnight temps dip below freezing. Get your fall planting done by late October and mulch around your new plants to insulate them through the winter.

🌧️ Worst Times to Plant in Chicago

Late Winter to Early Spring (January to Mid-April)

Why it doesn’t work:Chicago’s late winter months are cold, icy, and often leave the ground frozen solid or saturated with meltwater. Attempting to plant during this period can do more harm than good. The roots of young plants cannot grow in frozen soil, and digging into wet ground can compact the soil and damage its structure.

Tip:Use this time to plan, not plant. Finalize your landscaping design, choose your plants, and schedule installations with our team. Getting a head start on planning means you’ll be ready to hit the ground running in spring.

Mid-Summer (July to Mid-August)

Why it doesn’t work:While it’s not impossible to plant during the peak of summer, it is far from ideal — especially for less-established homeowners without automated irrigation systems. Chicago summers can bring heatwaves, high humidity, and long dry spells. These stress conditions can overwhelm new plants and make it difficult for roots to establish.

Risks of summer planting:

• Increased watering needs

• Greater risk of transplant shock

• Weaker root development

Tip:If summer planting is unavoidable, choose heat-tolerant varieties and be diligent about watering in the early morning or late evening. Better yet, let our landscaping experts install the plants and set up an efficient watering system to ease the burden.
