How Far Apart Do You Plant Leylandii Trees?

Leylandii trees are popular for their fast growth and beautiful appearance, making them perfect for use as a privacy screen or windbreak. One question that comes up often when it comes to planting these trees is how far apart they should be planted. The answer to this question depends on a few different factors, including the size of the trees at maturity, the purpose for planting them, and the conditions of the planting site.

The Size of The Trees At Maturity

The first thing to consider when determining how far apart to plant Leylandii trees is their ultimate size. Leylandii trees can grow up to 100 feet tall and 20 feet wide, so it's important to plan for their size at maturity when selecting a planting location. If you are planting the trees for a privacy screen or windbreak, you should consider planting them closer together to ensure a full, dense hedge that will provide maximum coverage. For Leylandii trees that will be used for ornamental purposes or to fill a large space, wider spacing may be more appropriate.

The Purpose for Planting Them

The purpose for planting Leylandii trees will also play a role in determining the ideal spacing between each tree. If you are planting the trees to provide privacy between your yard and a neighboring property, you will want to plant them closer together to ensure that there are no gaps in the hedge. If your goal is to create a windbreak or to provide shade, a wider spacing may be more appropriate as these trees can become very dense and block out sunlight.

The Conditions of the Planting Site

The conditions of the planting site will also affect the spacing between Leylandii trees. If you are planting the trees in an area with good soil, ample water, and plenty of sunlight, they will grow more quickly and require more space between each tree to prevent overcrowding. On the other hand, if you are planting the trees in soil that is less fertile or in an area with limited sunlight, they may grow more slowly and require closer spacing to ensure that they form a dense, healthy hedge.

Overall, the ideal spacing between Leylandii trees can vary depending on a number of factors. In general, it is best to plant the trees no closer than 3 feet apart, and no farther than 10 feet apart. This will allow enough room for the trees to grow and fill out, while still ensuring that they form a dense, uniform hedge. By taking the time to consider the size of the trees at maturity, the purpose for planting them, and the conditions of the planting site, you can ensure that your Leylandii trees grow strong and healthy, while providing the desired level of privacy or windbreak.
