Hello! I'm new to this forum and have zero gardening or landscaping experience. I also have killed every houseplant I've ever owned. Nevertheless, I have time now and I'd like to give this a shot...

I have a 12 foot long, extremely ugly retaining wall in my backyard that I want to hide. It sticks up about a 18 inches above the ground. I want to plant low hedges to hide it. From the little research I've done, it seems that dwarf English boxwood is a good option. I would like to know how close to the wall I can plant it so it takes up as little yard space as possible. I also have read conflicting information about how far apart to plant them. I want them to be as close together as possible so they really hide the retaining wall completely.

Thanks in advance!
Larry

I can't help, but Id like to say welcome to the forum! Someone should be along soon to answer your questions.

Tell us where in the world these plants will be growing: North Pole? South Pole? Death Valley? The Amazon?

All kidding aside, it is always more useful to provide climatic and soils/moisture/sun exposure information when you request advice about "what plant where". Your audience here comes from - literally - around the world.

Help us help you.

English boxwood will only grow 1 to 2 ft tall and 1 to 2 ft wide. So space them at 3 to 4 ft apart and give them plenty of time, its the slow way.

Another way which is faster, is to plant every ft and when the plants mature you remove the center plants as the outer plants touch.
