We recommend planting Leylandii, Laurel and most other evergreen shrubs* between 60cm and 100cm apart (approximately 2-3 feet apart). Hedges with plants 60cm apart "fill in" quicker than those planted 100cm apart but you get just as good a hedge in the long run at either distance apart..
Also to know is, when should leylandii be planted?
When is the best time to plant leylandii and other evergreen shrubs? The best time to plant is between September and March but container-grown plants can be planted at any time of year provided they are given sufficient water.
Also Know, how do you calculate plant spacing? To determine the total space needed by each plant, multiply the distance between plants within the rows (X) by the distance between the rows (Y). A. For a square planting pattern with plants spaced 6" on center (O.C.), X = 6 and Y = 6. Therefore, 6 × 6 = 36 in2.
Considering this, how far apart do you plant conifers?
