I don't know too much about grass but especially flowers. although I am learning from a course and on the job. But I want to be able to answer all my customers questions on what they need for their lawn.. Stuff like weed control, types of flowers or shrubs, seeding, getting growth out of a new lawn. Basically some general stuff but also goes into detail. I read stuff on the internet but I typically like to read before bed and I'm just looking for an informative book to gain some knowledge on property maintenance and maybe even some landscaping. Any recommendations that helped you out when you were a beginner? Thanx a lot!
