Late May, early September, mid-late October (winterizer -- lower nitrogen, higher potassium). Use slow-release fertilizers or organic fertilizers.
Add a mid-June (especially on sandy soil).
The fall fertilizations are the most important. Avoid early spring fertilizing. It can encourage fungal diseases. Avoid 'weed and feed' formulations. The best times to 'weed' and the best times to 'feed' don't neccessarily coincide.
When the forsythia bloom. The soil temperature at a two-inch depth should be around 50 deg. This is mid-April in Michigan and may be the same for you or slightly later (depends on where in Ontario you are located).
Your first mowing should be lower than you usually mow. And don't forget to sharpen your mower blade!
