The commercial property spring cleanup checklist
A commercial spring cleanup in Alberta runs in a fixed order between mid-April and late May: sweep up the winter's sanding chips and gravel, rake and power-rake the dormant turf once it dries, fertilize when the grass greens up, clean out the beds and top up mulch, assess trees and shrubs for winter damage, and start up the irrigation system. If you hold a grounds contract at the typical $800 to $2,000 a month, spring cleanup is usually included; booked standalone, expect roughly $500 to $2,500 or more for a commercial site depending on size. Here is the full sequence, the timing that Alberta's late melt forces on it, and which line items show up as extras.
Why the order matters
Alberta properties come out of winter buried in traction sand, gravel, and sander chips, and the turf underneath is dormant and often matted with snow mould. Sweep before you rake, or the rake throws gravel into the turf; rake before you fertilize, or the fertilizer feeds thatch instead of grass; and keep heavy equipment off the lawn while it is still wet, because compacting saturated spring soil does more damage than skipping a week. Most of these tasks sit inside a standard grounds contract — see our Alberta grounds and snow cost guide for what those contracts cost — but the sequence is the same whether one operator does it all or you book the pieces separately.
The spring sequence, in order
| Step | What happens | Typical Alberta window |
|---|---|---|
| 1. Gravel and sand sweep-up | Sweep sanding chips off walkways, entrances, and turf edges; power-sweep the lot | as soon as snow is gone, mid–late April |
| 2. Rake and power-rake | Clear debris and snow mould, dethatch once turf is dry and greening | late April – mid May |
| 3. First fertilization | Feed once soil reaches ~10°C and grass is actively growing | mid – late May |
| 4. Bed cleanup and mulch | Cut back perennials, edge beds, top up mulch | May |
| 5. Tree and shrub assessment | Prune snow-load breakage, check for sunscald and rodent damage | April – May |
| 6. Irrigation start-up | Pressurize zones, check heads, set the controller | after the last hard frost, ~mid May |
1. Sweep up the winter's gravel
A season of sanding leaves a surprising tonnage on a commercial site. The cities run the same operation at scale: Calgary's residential street sweeping starts around April 20 and runs into June, and Edmonton's spring sweep takes up to eight weeks — a good signal for when your own site is meltwater-free and ready. Walkway and turf-edge sweeping is grounds-crew work; clearing the parking lot itself takes a truck-mounted power sweeper, which is a specialty service — see our guide to parking lot sweeping and line painting.
2. Rake, then power-rake
Once turf is dry enough to walk on without footprints, a first raking lifts leaves, litter, and grey snow-mould mats so air reaches the crowns. Power raking (dethatching) goes deeper and only pays when thatch exceeds about 2 cm — done too early on wet, dormant turf it tears healthy grass out by the roots. The right window is just as the lawn begins to green, typically late April to mid-May depending on the melt.
3. Time the first fertilization
Fertilizing dormant grass wastes product and feeds early-germinating weeds instead. Wait until soil temperature reaches roughly 10°C and the turf is actively growing — mid to late May in most Alberta cities, earlier in a warm spring in Lethbridge, later after a long melt. Anyone applying commercial-class fertilizer or herbicide on your property should hold Alberta pesticide applicator certification.
4. Beds, edging, and mulch
Cut back last year's perennial growth, pull winter-killed annuals, re-cut bed edges, and top up mulch to 5–8 cm. Fresh mulch is the highest-visibility item on this list — it is what tenants and customers actually notice — and it suppresses the weed flush that follows spring moisture.
5. Assess trees and shrubs for winter damage
Alberta winters break branches under snow load, split bark on the south side of young trunks (sunscald), and let voles girdle shrubs under the snowpack. A spring walk-through catches hazards over walkways and parking stalls before they fail in a summer storm. Light pruning is grounds work; removals and anything near power lines is arborist work, billed separately.
6. Start up the irrigation
Once hard frosts are done — around mid-May — the system is repressurized zone by zone, heads are checked and adjusted, and the controller is set for spring watering rules. Start-up pairs with the fall blowout, and both are classic billed-extra line items; see our irrigation blowout cost guide for what the pair costs across the year.
Included in the contract, or billed extra?
A standard Alberta grounds contract covers spring and fall cleanups, mowing, fertilization, and bed maintenance as part of the monthly rate. The usual extras: irrigation start-up and blowout, arborist-level tree work, landscape construction, and parking-lot power sweeping and line painting, which need equipment the grounds crew doesn't carry. If a cleanup quote looks cheap, check which of these it silently excludes — the same advice we give for snow scopes in the cost guide.
The copyable checklist
- ☐ Walkways, entrances, and turf edges swept of sand and gravel
- ☐ Parking lot power-swept (specialty — book separately or confirm it's in scope)
- ☐ Turf raked; power-raked only if thatch > 2 cm and lawn is greening
- ☐ First fertilization scheduled for soil ~10°C (mid–late May)
- ☐ Beds cut back, edged, mulch topped to 5–8 cm
- ☐ Trees and shrubs inspected for breakage, sunscald, rodent girdling; hazards over walkways pruned
- ☐ Irrigation started up after last hard frost; heads checked, controller set
- ☐ Winter damage to turf edges from plows logged for repair
- ☐ Confirmed in writing which items are contract-included vs extra
Frequently asked questions
When should spring cleanup happen on a commercial property in Alberta?
Between mid-April and late May, driven by the melt: sweeping as soon as snow is gone, raking and power raking once turf is dry and greening, fertilizing when soil reaches about 10°C, and irrigation start-up after the last hard frost around mid-May.
Is spring cleanup included in a commercial grounds contract?
Usually yes — spring and fall cleanups are standard inclusions in a monthly grounds contract. Irrigation start-up, arborist tree work, and parking-lot power sweeping are the common billed-extra items.
How much does a commercial spring cleanup cost?
Inside a grounds contract it's part of the $800 to $2,000-plus monthly rate. Booked standalone, a commercial spring cleanup typically runs roughly $500 to $2,500 or more depending on property size and how much sand and debris winter left behind.
When should you power rake in Alberta?
Just as the lawn begins to green up, typically late April to mid-May, and only when thatch is thicker than about 2 cm. Power raking wet, dormant turf earlier than that pulls healthy grass out and sets the lawn back.
