Quick Answer: Bag or Leave Clippings in Fort McMurray?
For most Fort McMurray lawns, it’s better to leave grass clippings on the lawn as long as:
- You mow regularly (about once a week in peak season)
- You’re not cutting off more than one‑third of the grass blade
- The clippings are short and evenly spread, not big clumps
You should bag clippings when:
- The grass is very long or wet
- You’re dealing with heavy weeds going to seed
- You have a fungal disease that you don’t want to spread
How Grass Clippings Work in Our Climate
Q: What happens to grass clippings if I leave them?
Grass clippings are mostly water and nitrogen. In Fort McMurray’s cool‑season lawns, short clippings:
- Break down fairly quickly
- Return nutrients to the soil
- Help the lawn stay greener with less fertilizer
Because our growing season is short, recycling nutrients through clippings is especially useful. You get more out of each mow.
Do Grass Clippings Cause Thatch?
Q: If I leave clippings, will they cause thatch?
No. This is a common myth.
- Thatch is a layer of dead roots, stems, and crowns just above the soil
- Short grass clippings are mostly leaf tissue, which decomposes quickly
- Clippings rarely become part of the thatch layer
In Fort McMurray, thatch problems are more often related to:
- Over‑fertilizing
- Compacted soil
- Certain aggressive grass types
Leaving short, finely chopped clippings on the lawn does not usually create thatch.
Benefits of Leaving Clippings on the Lawn in Fort McMurray
1. Free Fertilizer
Clippings can return up to 25–30% of the nitrogen you’d otherwise apply with fertilizer. That’s important in a short, intense growing season.
2. Better Moisture Retention
A light layer of clippings:
- Helps shade the soil
- Reduces evaporation
- Helps the lawn handle dry, sunny periods better
3. Less Time and Less Waste
- No need to stop and empty bags all the time
- Fewer bags of yard waste to manage or haul away
For many Fort McMurray homeowners, mulching clippings fits perfectly with a simple, efficient mowing routine.
When You Should Bag Grass Clippings in Fort McMurray
There are times when bagging is the better choice.
1. When Grass Is Very Long
If you’ve missed a mow and the grass is much taller than usual:
- You’ll be removing more than one‑third of the blade
- Clippings may form heavy clumps that sit on top of the lawn
In this case:
- Raise the mower height, take a first pass
- Consider bagging or raking big clumps
- Make a second, lower pass a few days later if needed
2. When the Lawn Is Wet
Wet grass tends to:
- Stick together and form clumps
- Stick to the mower deck and leave messy trails
If you must mow wet:
- Consider bagging or raking afterward
- Try to spread out clumps so they don’t smother the grass underneath
3. Heavy Weed or Seed Heads
If your lawn is full of:
- Dandelions gone to seed
- Other weeds with mature seed heads
Bagging can help reduce how many seeds get dropped back into the lawn.
4. Disease Problems
If you see:
- Patches of fungus
- Discoloured areas that look diseased
Collecting and removing clippings from those areas can help reduce spread. Pair this with proper watering, mowing height, and, if needed, a fungicide program.
Mulching vs Bagging: What’s Best Overall for Fort McMurray?
Q: Is it better to mulch or bag clippings in our climate?
For a typical healthy Fort McMurray lawn:
- Mulching (leaving clippings) is better most of the time
- Bagging is a situational tool for long, wet, weedy, or diseased grass
A good rule of thumb:
- If clippings are short and you can’t clearly see them covering the lawn, leave them.
- If you see thick clumps or a heavy layer, bag or spread them out.
How to Leave Clippings Without Making a Mess
1. Mow Often Enough
- In peak growing season, aim for once per week
- Follow the “one‑third rule”: never remove more than one‑third of the blade
2. Keep Your Mower Blades Sharp
Sharp blades:
- Cut cleaner, finer clippings
- Help clippings drop down between grass blades instead of sitting on top
3. Use a Mulching Mower or Plug (If Available)
A mulching mower or mulching plug:
- Circulates clippings inside the deck
- Cuts them into smaller pieces before they fall
This isn’t required, but it improves results.
