how far apart to plant juniper trees
This is the one time to plant the trees in a dense row, creating a wall of greenery. You can plant American arborvitae trees (Thuja occidentalis) 3 feet apart, but most evergreens need more space. For instance, cedars and junipers need 6 to 8 feet between them, while pines and spruces need 10 to 12 feet of spacing. Before you plant, measure the space and mark the planting sites with stakes, then tie a string between them to ensure you have a straight row.
