I can get about 2 or 3 hundred cleyera shrubs for free from a nursery that i do business with. They are throwing them away because they are to big for their pot size. I want to plant about a 250 foot screen to block my back yard. How will these do?? I dont want them to get out of control,, and i was thinking once a year i could just bushog the screen to keep them in check. I would plant them maybee 2 feet apart?? What yall think?? Got a pick up load 2-day attached are pics
