Fall is the Best Time to Improve your Lawn

With cooler nights as well as more and longer lasting dew on the ground each morning, fall is the best time to improve the quality of your lawn. If your lawn looks terrible due to the long drought we endured this summer, this post is for you!

Recovering from Summer

My lawn held up amazingly well (some weeds moved in along the curb, but the grass recovered) in the drought this summer, much better than many others in my neighbourhood, and also much better than it ever has other summers. I suspect the TLC I showed it last fall is the reason for that.

Fall Lawn Regime

That sign of success means I will be following a similar protocol this season:

  • aerating
  • adding composted manure and seed
  • applying a fall fertilizer six weeks after seeding
  • cutting the lawn shorter than usual before the first snowfall


When you aerate, ensure you use a proper aerator (hire someone to do it for you) that digs out plugs of soil. The inexpensive, so-called aerating tools that you step on do more damage to your lawn as they compact the soil instead of aerating it.

Composted Manure vs Garden Soil for Lawns

I choose composted manure, either sheep or cattle/steer, because I have yet to find a bad bag of it. By bad I mean no weeds or junk in it. In the past I have purchased bags and loads of soil, from garden soil to black earth, that were loaded with weeds seeds, garbage and even cigarette butts. Never again! You can purchase composted manure at Home Depot, Lowes or locally at Ritchies Nurseries. I would not however, recommend the brand that Canadian Tire sells.


If you plan to fertilize your lawn, pay attention to the three numbers on the bags. In order, they represent the nutrient levels of Nitrogen, Phosphate and Potash/Potassium in the fertilizer. In September, as lawns recover from the summer weather, choose a fertilizer highest in Nitrogen for a slow growth.

Later in the fall, choose one with a higher middle number to stimulate root growth and protection over the winter.


If you plan to reseed because your lawn has bare spots and lots of weeds, you should wait six weeks after seeding to apply fertilizer. Be sure too to invest in grass seed specific for your location and sun exposure. If you are one of the lucky ones and do not plan/need to reseed, you can fertilize twice as indicated, once now (September) and again in November.

I promise, it’s not nearly as complicated as it sounds! Next summer your lawn will be grateful for the extra TLC you provide this fall.
