October comes fast in Winnipeg. One weekend you're raking in a light jacket. The next, a cold front rolls in and the forecast says snow. The fall yard window is shorter than it feels, and what you get done before the first snow that stays decides how your lawn and garden look in May.
TL;DR: Get every leaf off the lawn, step the last mow down, cut back perennials after the first killing frost, clean the eavestroughs, and have your yard waste bagged before the City's last pickup on November 20 (area A) or November 27 (area B).
Key takeaways
- Start in mid-September. Finish the important jobs before the first snow that stays.
- Get the leaves off the lawn. Wet leaves matted under snow are how snow mold starts.
- Wait for the first killing frost before cutting back most perennials.
- Clean eavestroughs and downspouts once most of the leaves have dropped.
- Bag leaves for City pickup. The last 2026 collection is November 20 (area A) or November 27 (area B).
This guide covers every job to finish before freeze-up: when to do it, why it matters, and how. If you'd rather hand it off, see our fall cleanup service in Winnipeg.
When Should You Do Fall Yard Work in Winnipeg?
Start in mid-September and finish before the first snowfall that's forecast to stay. You don't have to do it all in one day. Think of fall yard work as a window. It opens in mid-September. It closes at freeze-up, which in most years means late October, or early November at the latest.
A rough timeline
| Task | When to do it |
|---|---|
| Leaf removal (first pass) | As soon as significant leaves are falling, typically early to mid-October |
| Final mow | After the last strong growth flush, before the first hard frost |
| Garden bed and perennial cutback | After the first killing frost, usually mid-October |
| Eavestrough cleaning | After most leaves have dropped, late October |
| Last leaf pass and bagging | Before the first snowfall that is forecast to stay, and before City yard waste pickup ends (November 20 or 27 in 2026, depending on your collection area) |
The pressure is real. An early snowfall on a yard full of leaves can shut the window before you're ready. Watch the extended forecast through October, and don't wait for the last leaf to fall before you start.
From our crew: the mistake we see most is waiting too long. Many homeowners hold off until every leaf has dropped, and then the first snow hits and buries everything. Another is raking once in early October and thinking the job is done, when the oaks and elms are still dropping.
What Happens If You Leave Leaves on Your Lawn Over Winter?
The grass underneath can get snow mold, a fungal disease that thrives when wet leaves mat the lawn down before snowfall. It's easy to think the snow will take care of them. Or that they'll just break down. They won't. And the damage shows up in May.
What happens under the snowpack
Wet leaves form a mat. The mat blocks light and air from the grass below. By the time snow lands on top, the damage has already started, and months under the snowpack only speed it up.
Snow mold loves a Winnipeg winter. Deep snow. A slow spring melt. Months of cold, damp conditions under the surface. Two types show up on local lawns each spring:
- Grey snow mold (Typhula blight): circular patches of matted, greyish-white grass
- Pink snow mold (Microdochium patch): similar patches with a pinkish tinge at the edges
Bad cases take a long time to recover and sometimes need a fungicide. The best prevention is simple: get the leaves off before the snow.
What we find in west Winnipeg yards: the most common problem in Charleswood and St. James in late October is wet leaves matted flat on the lawn, especially under the big elms, ash and maples on the older streets. Once they mat down they smother the grass. If they sit under the snow all winter, the lawn usually comes up in spring with brown, dead patches and snow mold. Clogged eavestroughs and leaves packed into window wells and against fences are close behind.
Should You Rake, Bag, or Mulch Your Leaves?
It depends on how many leaves you have. A light layer can be mulched in place. A heavy one has to come off the lawn.
Light leaf fall: mulching works
If the leaves are light and scattered, run them over with a sharp mower blade. The mower chops them fine. The pieces settle between the grass blades and break down over the season, putting a little organic matter back into the soil. But this only works when the layer really is light.
Heavy leaf fall: remove them entirely
Big trees, or several dropping at once, are a different story. Mulching can't keep up. Thick chopped leaves still mat together and choke the grass, the same as whole ones. Rake or blow them off the lawn and bag them.
A few tips:
- Don't wait for every tree to finish. Rake in passes as the leaves come down.
- Pay extra attention under large trees, where leaves pile deepest.
- If leaves look diseased (spots, odd discolouration), bag them instead of composting. Disease can carry over.
- Leaves you rake off the lawn can go out for the City's curbside yard waste pickup (more on that below).
How Short Should the Last Mow of the Season Be?
Finish a little shorter than your summer height, but don't scalp it. Go too long or too short and the lawn pays for it over winter.
- Too long: Tall grass mats down under the snow and traps moisture against the crown for months. That's exactly what snow mold needs. Leaving the grass long going into winter is one of the most common mistakes our crew sees.
- Too short: A very short cut strips the leaf tissue the plant uses to store energy for winter, and it leaves the crown exposed to cold, drying wind. A scalped lawn is slow to come back in spring.
Don't try to get there in one cut. Drop the mower deck one notch at a time over the last two or three mows. Mow on a dry day when the grass isn't frozen. On the final pass, bag the clippings so less material sits on the turf all winter.
Keep mowing until the grass stops growing. That point changes from year to year. Watch the lawn, not the calendar.
When Should You Cut Back Perennials in Fall?
Wait for the first killing frost, then cut most perennials back to a few centimetres above the soil. Fall is the right time to clear the beds. The timing is just a little different from the lawn.
Wait for the first killing frost
Cut too early and the plant may push out new growth. That growth won't harden off before winter. So wait. Once frost has killed the tops, cut the stems down to a few centimetres above the soil.
A few things to keep in mind:
- Remove diseased plant material. Bag anything that shows signs of disease instead of composting it. Diseased stems left in the bed give spores a place to spend the winter.
- Leave some stems if you like. Ornamental grasses and seed-bearing perennials can stay up for winter interest. Still pull out anything diseased or matted.
- Clear fallen leaves from the beds. Leaves packed down over winter can smother perennials as they come up in spring.
- Don't fertilise perennials and shrubs late. High-nitrogen fertiliser on garden beds late in the season pushes soft growth that won't harden off before winter. This applies to your beds, not your lawn.
Pull annuals out completely once frost kills them.
One more thing our crew sees every fall: shrubs and perennials cut back too hard, or the wrong plants pruned.
How Does City of Winnipeg Yard Waste Collection Work?
The City picks up yard waste every two weeks on your regular collection day. In 2026 the last pickups are November 20 in collection area A and November 27 in area B, weather permitting. Containers go out before 7 a.m. Here's what else to know so you don't miss a pickup.
How the program works
Look up your collection area and schedule at myutility.winnipeg.ca.
Use any reusable container without a lid (plastic tubs, old blue boxes), a cardboard box, or brown paper yard waste bags from most local stores. Keep each one under 50 pounds (22 kg). Leaves, grass clippings, plants, crab apples and unpainted pumpkins all go in. So do branches, if they're bundled, no more than 10 cm (4 in.) across and no longer than one metre.
Missed the last pickup? Take yard waste to one of the City's 4R Winnipeg Depots, at 1825 Brady Rd., 1120 Pacific Ave., and 429 Panet Rd.
Do not rake leaves onto the street
Keep leaves out of the street and out of the ditch. Leaves in the street plug storm drains. Plugged drains cause ponding, and ponding raises the risk of basement flooding. The City's street and boulevard cleaning page puts it plainly: "Please do not rake yard waste or other debris onto streets for us to clean up." Keep leaves on your property until they're bagged and ready for pickup.
How Do You Get Eavestroughs Ready for Winter?
Clean them once most of the leaves have dropped, usually in late October. A blocked trough can't drain. The water backs up. Then it freezes, and it can damage the trough or work its way under the roofing.
Scoop out the leaves. Run water down each downspout to make sure it flows. Check that the extensions carry water away from the foundation, and look for sags or sections pulling away from the fascia. Precision Property Services doesn't clean eavestroughs. If your home is two storeys, or the roof is hard to reach by ladder, hire an eavestrough cleaning company to do it safely.

- Bag leaves in reusable containers or brown paper yard waste bags (max 50 lb / 22 kg each)
- Bundle branches (max 10 cm diameter, 1 m long); unpainted pumpkins can go in too
- Put yard waste out before 7 a.m. on collection day
- Don't rake leaves onto the street or into the ditch
Eavestroughs
- Wait until most leaves have dropped, then clean the troughs and flush the downspouts

Rather Hire It Out?
If that list feels like a lot to get through before freeze-up, Precision Property Services handles fall cleanups for homeowners in Charleswood, St. James, Westwood, Sturgeon Creek and approved Tuxedo streets (postal codes R3R, R3J, R3K, R2Y and approved R3P streets). Fall cleanups start at $200 plus GST.
On a standard St. James lot, a two- or three-person crew is usually done in 2 to 3 hours. That covers raking or mulching leaves, clearing dead plants out of the beds, a final short mow, and bagging. Bigger, heavily treed lots in Charleswood take longer, often 4 to 6 hours, especially when leaves have been piling up since September. We don't trim garden beds or cut back perennials. We clear out the dead plant material.
