Weed control is worth it. I don't know about your personal area but in my area it is worth it. What I come across is that a lot of home owners are do it your selfers in that aspect along with fertilization. Now on commercial propertys its a different story. Like wise, in my area we have a far amount of storm damage every summer so tree care and removel is worth it. So the only solid answer I can give you is that it really depends on the location and the needs of your customers.
