Looking for a screening plant to put up against a low metal bar fence we have running along the side of our property to give some privacy for our deck which is next to the yard and also to make it easier for the dog to chill on the grass without getting worked up by passers by. Looking at around 3m high, don't want anything too big that would be overly imposing or hard to manage. The tricky part of the area is that its wedge shaped, with the narrowest part being around 2m in width from the fence to the property and then getting wider to about 4-5m at the other side. I've had a look at some plants like murraya's or camelia's but worried they might grow too thick and essentially block off a path to the yard at the narrow entrance. Would looking for a thin type of bamboo be a better option? Any advice appreciated as I'm pretty novice at gardening, cheers.
