The most common question we get from prospective landscape clients in the Rockford area: "If I call you today, when can the work start?"
The honest answer depends on what month it is. Landscape design-build in northern Illinois follows a real seasonal pattern — driven by ground conditions, plant availability, designer capacity, and crew scheduling. Calling in February gets you an installation slot in May. Calling in May usually gets you August or later. Calling in July often means waiting until the following spring.
This guide breaks down what to expect month-by-month, and how to time a project to land when you actually want it finished.
The Short Version
For most residential landscape design-build projects in northern Illinois:
- Site consultation: scheduled within 1–2 weeks year-round
- Design phase: 3–4 weeks for typical projects
- Approval and material ordering: 2–4 weeks
- Installation window: typically April through November in our climate
- Frozen-ground delay: December through March, some hardscape work continues but planting is limited
So a project initiated in May realistically installs in August at the earliest. A project initiated in October installs the following May. The math is straightforward once you know it.
Month-by-Month: When to Start
January–February
The best time to start a design project if you want it installed during the spring or early summer of the same year.
What we're doing in our shop during these months:
- Designing for spring and summer installations
- Producing 3D renderings (most complex design work happens here, before the build season starts)
- Ordering specialty materials (some pavers and stone have 4–8 week lead times)
- Confirming installation schedules and putting customer projects on the calendar
What you should be doing if you want a spring install:
- Schedule the consultation now
- Be prepared to approve a design by mid-March
- Expect installation start dates in April or May
The catch: our most-requested designers fill their winter capacity by late January most years. Call earlier rather than later.
March
Still good timing if you want a late-spring or summer installation. Design capacity is tighter than January–February but still available.
What's happening on the ground:
- Frozen ground prevents most excavation through mid-March in typical years
- Hardscape pre-fab work (cutting custom stone, building wall sections) continues in shops
- Plant material starts arriving at suppliers
What you should be doing:
- Schedule the consultation now if you want a May or June install
- Plan for a slightly compressed design phase
- Be flexible on start dates — early-spring weather is unpredictable
April
This is when the build season visibly starts in northern Illinois. Crews are working most days. Design teams are simultaneously closing out winter designs and beginning the next wave.
If you start a project in April:
- Consultation within 1–2 weeks
- Design in 3–4 weeks (April–May)
- Realistic installation start: late June through August
This is the most common "I want this fixed by summer" timeline. It works, but the project lands in late summer, not early summer. People who wanted to enjoy the new patio for July 4th are typically frustrated.
May
Already late for current-season installations on anything but small projects.
Most firms (us included) have summer crew schedules locked by May. Adding a project to the schedule now means either:
- Late-season installation (September–October), or
- Following spring
This is the inflection point in the year. Before May, you can usually still get current-season installation. After May, you're usually scheduling for next year.
June–July
We continue to take design consultations year-round, but if you call us in mid-summer:
- Consultation happens within 1–2 weeks
- Design happens summer/early fall
- Installation typically lands the following spring or early summer
This isn't bad. It's actually a smart way to plan. Designing during summer when you can see how you actually use the existing outdoor space — what works, what doesn't, where the sun is, when shade matters — produces better designs than designing in winter from memory.
August–September
Excellent time to design for the following year. Build crews are still active; designers are starting to look at their winter capacity.
The benefit of an August consultation: the property is fully leafed out, all flowers in bloom, sun patterns visible, drainage issues evident after summer rains. The designer sees everything.
If you start a project in late August or September:
- Design completes by November
- Project signed and on the schedule for the following spring
- Installation starts April or May
- You have the entire winter to plan, adjust, refine, or change your mind
This is our preferred timing for clients with patience. The result is usually better because everyone has time.
October
Last realistic month to start a project for current-season installation, and only for smaller projects (small patio, planting refresh) that can fit in a 4–6 week build window before the ground freezes.
For most projects, October consultations design through November–December and install the following spring.
November–December
Genuinely difficult months to start a new project for installation. Some firms (us included) take consultations year-round and use the winter for design. Build crews are typically off the road by mid-December in our region except for emergency tree service and snow removal.
If you call us in November or December:
- Consultation happens within a week or two
- Design happens through January
- Materials ordered February
- Install starts April
That's actually a reasonable timeline if you can wait — you get to use winter for design refinement and end up at the front of the spring queue.
Why the Seasonal Constraint Is Real
A few reasons landscape installations don't run year-round in northern Illinois:
Frozen ground
Excavation in frozen clay is brutal — slow, expensive, and damaging to equipment. Most contractors won't even quote excavation work between mid-December and mid-March in our region.
Concrete and masonry temperature limits
Polymeric joint sand requires above-freezing temperatures to set. Concrete footings and masonry work require above-freezing for proper cure. These constraints rule out late November through early April for most hardscape installations.
Plant availability and dormancy
Nurseries dig dormant stock in spring and fall. Plants installed in dormancy establish faster than mid-summer plantings. Late spring (April–May) and early fall (September–October) are the prime planting windows. Mid-summer plantings work but require careful watering through establishment.
Crew capacity
Landscape construction crews in our market run six-day weeks April through November. Adding capacity beyond the existing crew base requires hiring trained people, which we do incrementally — but there are no spare crews sitting around in July waiting for a new project.
Designing for the Project You'll Actually Have
A practical recommendation: think of a landscape design project on a 12-month horizon, not a 12-week one.
If you want to enjoy a new patio with your family in summer 2027, start the design conversation in summer 2026. By the time you've consulted, designed, refined, approved, and installed, that 12-month window will feel about right. Compressed timelines work — most of our projects compress to 4–6 months from consult to completion — but the projects that get the best result are the ones where everyone had time to think.
What Tree Care Enterprises Does
Tree Care Enterprises schedules landscape design consultations year-round, typically within 1–2 weeks of your call. Design work happens continuously regardless of season. Installations run primarily April through November based on ground conditions and crew availability.
Some specifics worth knowing:
- Free site consultation — no fee, no obligation. We visit your property, walk the site with you, and tell you honestly whether what you want is feasible and roughly what it will cost.
- Design fees roll into build cost — there's no separate design invoice on signed projects.
- Tree-aware design — our ISA Certified Arborists consult on any project near a mature tree. This is the central thing we do differently from general landscape contractors.
- In-house crews — design and installation by the same team, no subcontracted hardscape.
When to Pick Up the Phone
A rough decision tree:
- Want it installed this spring/early summer: call in January–February
- Want it installed this late summer/fall: call in March–April
- Want it installed next spring: call in August–October — this is actually our preferred timing for clients
- Want to start design without immediate install: call any month
- Have an active issue (failed retaining wall, drainage problem, dying landscape): call now regardless of season
Call 815-965-5757 or request a free consultation online. We'll schedule the site visit, listen to what you want, and tell you honestly when installation could realistically happen.
