About Leyland Cypress Trees For Georgia Gardens

By Catherine Stone


Choosing the right trees for your garden can be fun, but it certainly should be planned. Trees are often expensive, they take a bit of trouble to plant, and they require care for the first year after planting. They also grow bigger than your average garden plant, so spacing and placement are important. Leyland cypress trees are easier than most, but homeowners in Georgia still need to plan ahead.

This extremely popular variety of landscape tree is not native to anywhere. The first examples of this conifer (cone bearing evergreen) grew on a British estate as a hybrid between two cypress species. Some Monterey cypress were planted near some Nootka cypress and they cross-pollinated. The new trees were emerald green, well-shaped, and extremely fast growing. Other landowners had the same serendipity; there are over 40 types of the species today.

The Leylands are often marketed for hedges or windbreaks. They grow well in urban areas, being tolerant of air pollution, and also thrive along the coast, since they can withstand salt spray. They grow rapidly into effective windbreaks and are tolerant of drought. Their soft branches are easy to prune, a necessary practice to keep them from growing too tall. Usually you won't want a hedge to grow to extreme heights. The shallow-rooted Leyland can blow over in a stiff wind if allowed to get too tall.

The tree is sturdy and not prone to many diseases if well situated, but it is shallow rooted. A strong wind may blow it over after it gets tall, and it is subject to damage from heavy snows. Because of the shallow roots, it does not do as well in extremely hot and dry climates. However, watering once a week can overcome this difficulty.

They grow up to four feet a year, increasing in diameter, too. A mature Leyland can be over 100 feet tall and 25 feet wide. They don't like wet soils but otherwise are remarkably tolerant of soil types. Georgia's planting zones are perfect, since the tree prefers zones 6 to 8. However, you find Leylands all over from zone 5 to 10. Full sun is best for these fast-growing evergreens, but they can make do in light shade.

Although most people recognize this tree as a hedge or planted in a line along the border of a property, it also makes a magnificent specimen when planted alone. Nursery-grown plants are started from cuttings rather than from seed and have a fuller, more symmetrical shape. If conditions are ideal, it can reach a height of over 100 feet and spread to 25 feet around. Most of the original hybrids are still alive in Britain, which makes them about 125 years old and still going strong.

If used in a hedge, trees should be at least 5 feet apart at planting time. It's wise to schedule annual pruning to keep them from growing too tall (height and width should be balanced). Over-crowding makes them susceptible to disease and may cause the lower branches to die.

The popularity of this tree is partly because they are relatively inexpensive and easy to grow. However, their beauty also makes them desirable. In Georgia, homeowners should check their planting zones, make sure that such a vigorous variety won't shade neighboring properties, and make sure the plants they choose are started from cuttings. If conditions are favorable, the Leyland cypress should be a joy for many years to come.
