Best I know, most lawn care services go hand in hand with full landscape maintenance. That means that landscape maintenance companies need to know turf ID and fertilizer stuff, but if they are applying herbicides to beds, they need to know most of their plant ID for shrubs, trees and flowers to adhere to the label instructions. Also involved is a myriad of things like insect knowledge, turf diseases, plant diseases, proper pruning, winter preparation, scheduling and irrigation needs of most plants. With all those things being a requirement to be the best at what you do, or for what you advertise for, where do you rate your knowledge and ability on a scale of 1 to 10 ?? Nobody is perfect, so let's say that the "Great Knowitall" would be an 11 or a 12 off the scale. So what would be a fair estimation of where you are located on the totem pole of skill? Will list as many choices as the poll allows.
