1.  Why is Healthy-Lake Lawn Care is SO important?                    

  •  To limit excess nutrient from going into the lake.
  •  1lb of phosphorus can produce at LEAST 500 lbs of algae!
  •  The correlation of phosphorus to algae is the same as nitrogen to algae.
  •  Synthetic fertilizers suppress the healthy microbrial life in the soil. 
  •  The science and the survey on fertilizer use in the Pigeon Lake Watershed told us that nutrients are entering the lake from all around the lake and that lawn fertilizers  is one of the key sources.
  •  Over 40% of the nutrients entering the lake from external sources come into the lake from diffuse sources (e.g. stormwater runoff).
  •  Nutrients feed the aquatic plants and algae.

2.  PLWMP Recommendations                                                     


The PLWA, in accordance to the the PLWMP Cosmetic Fertilizer & Soil Management Committee drafted recommendations is providing information and education about "Healthy-Lake Lawn Care" (see information & resources below). 

The draft recommendations are that:

1)  The use of residential lawn fertilizers be eliminated in the watershed and at the same time alternative practices be promoted.

2)  Local Governments in the watershed bring in consistent regulations prohibiting the use of lawn fertilizers.

3)  Watershed stakeholders advocate to the Province of Alberta to introduce legislation similar to the “Nutrient Management Act” of the Province of Manitoba.

4)  The PLWA work in partnership with local governments to provide outreach and education related to lawn fertilizer elimination and alternative practices.

5)  Further review of lawn herbicides (and other lawn care chemicals), be undertaken by the Cosmetic Fertilizer and Soil Nutrient Subcommittee.

This is all about moving away from synthetic fertilizers and harmful chemicals towards healthy soils that are self-sustaining and supportive of healthy lawns.

As the recommendations state, it is best to eliminate all use of any fertilizers. 

Please wean your lawn off the synthetic fertilizers using the recommended organic products that will assist the soil to move towards being a healthy, self-sustaining lawn that will only need spot treatments in the future.

When my lawn needs help, what else do soil experts say?

How Do I Deal with Dandelions? 

1. Accept them and mow them.

2. Pick’em and Eat’m. Dandelions are high in vitamins A and C, and contain impressive levels of iron, calcium, phosphorus, potassium, magnesium, and copper.

3. Pick’em & Compost’m. Return them as composted nutrients to spots in the yard that need help without adding more nutrients into the watershed.

4. Dig them out – trying for the whole root. Diggers available. Careful: Activity can be addictive - once you start it is hard to stop.

5. Vinegar – Spray regularly with a strong acid base vinegar. Take care you do not spray the plants you want.

6. Boil them – Pour boiling water on them.

But I have WAY TOO MANY!  Well then, maybe time to start over.  Cover the area with weighted down cardboard or black plastic and you will kill all the ground cover by depriving them of sunlight.  All plants need sunlight so blocking it out will eventually kill them and you can then seed new grass with the recommended mix of seed.  This can take a little time but better for the soil and lake then killing them with chemicals.
