So I'm 17 years old, almost 18 and I've had a registered Lawn mowing business for 3 years. I've built up a strong customer base, trying to fill up my time space while I'm not in school. This year I began doing some landscaping work, including, mulching, weeding, pulling out small trees and stuff and have been making pretty amazing money whenever I do these jobs. So basically I want to get into landscaping. My business is doing well right now since I'm doing good work for all of my customers, the thing is I don't know much about landscaping. I really want to learn, are there any good books or materials I can learn from so that I can start doing some landscaping jobs? Thanks guys!
