Q: I took down a couple of huge Leyland cypress and have a few ‘Emerald Green’ arborvitae for replacements. How far do I need to space them to make a screen?
A: ‘Emerald Green’ arborvitae makes a nice substitute for a too-tall Leyland cypress. They grow 12 – 15 feet tall and 3 – 4 feet wide so I’d space them 4 feet apart. Fertilize twice each year (April and June) to help them grow as much foliage as possible.
