I need some info on what fertilizer to use here in Ontario and how many apps and when to apply. I haven't done much before and have to price a few jobs that want it included. Most places I know of only do a Spring and Fall application here. I will be including weed spraying as well in the bids so any info on that would be good too. I have done spraying before so it shouldn't be a problem. They want a price to spray it twice a year but there are very few weeds in the lawn, I am considering just spot spraying several times where needed.
