Most of our customers are looking for a screen, usually tall and the sooner the better.  Bamboo is ideal.  Nothing else will give you the heigth and density of as quickly as bamboo, usually in just a few years. We have varieties that range in heigth from a few feet to 60 or more feet tall.  Bamboo is an evergreen so you will have year around privacy and screening. Many are extremely cold hardy meaning they will stay green down to well below zero.  Usually a grove just a few feet thick can provide complete privacy.  I generally recommend planting most screening bamboo species about every 5 feet in order to have a screen in 3 to 5 years.  Fertilizing, mulching, and watering during dry spells is the best way to achieve the privacy you want. Bamboo is a giant grass and is a heavy feeder.
