When we plant a tree we all want to see it grow quickly, establish itself and rapidly become a part of our garden. There are specific trees which will provide this fast-growing solution.
Fast-growing trees are a great choice for gardeners who want to quickly create privacy, establish shelter, or add structure and beauty to a landscape.
Our temperate climate, with moderate rainfall and relatively mild winters, supports a wide variety of species that can put on rapid growth when given the right conditions.
However, choosing the right tree involves balancing speed with factors such as maintenance, root spread, soil type, and long-term size. Here are our six standout fast-growing trees that will thrive in gardens, each offering distinct advantages.
1. Leyland Cypress
This is one of the most popular choices, an evergreen conifer which is widely known for its exceptional growth rate, often reaching 60–90 cm per year under ideal conditions. It is commonly used for hedging because it forms a dense, tall screen very quickly, making it ideal for privacy. Leylandii tolerates a wide range of soils and coastal conditions, which adds to its appeal. However, it requires regular pruning to keep it under control, as it can quickly grow too tall and dense if neglected.
2. Silver Birch
Is another excellent fast grower which is native to the UK, and this elegant deciduous tree is loved for its distinctive white bark and light, airy canopy. It can grow around 40–60 cm per year and is particularly suited to smaller gardens because it doesn’t create overly dense shade. Silver birch thrives in poor soils and exposed locations, making it a resilient and low-maintenance option. In autumn, its leaves turn a soft yellow, adding seasonal interest.
3. The Hybrid Poplar
Is another top contender for rapid growth. Often used in forestry and large gardens, this tree can grow up to two metres per year, making it one of the fastest-growing trees in this country. Its tall, upright form makes it ideal for windbreaks or screening large areas. However, hybrid poplars require plenty of space due to their size and extensive root systems, which can interfere with nearby structures or drainage systems if planted too close.
4. The Weeping Willow
For those seeking a fast-growing tree with ornamental appeal, the weeping willow is a striking option. Known for its graceful, drooping branches, it can grow up to a metre per year. This tree thrives in moist soils and is often planted near ponds or streams. Its dramatic appearance makes it a focal point in any landscape. However, like poplars, willows have aggressive root systems and should be planted well away from buildings and underground pipes.
5. The Eucalyptus
Also known as cider gum, has become increasingly popular in UK gardens. It is an evergreen tree that can grow two metres per year when young, producing attractive blue-green foliage with a distinctive fragrance. Eucalyptus is relatively hardy in many parts of the UK, especially in sheltered locations, and responds well to pruning. It is a good choice for adding height and year-round interest quickly, though it may require protection in particularly cold regions.
6. Common Alder
Finally is a native species that combines fast growth with ecological benefits. Growing around 60–90 cm per year, alder is particularly suited to wet or waterlogged soils where other trees might struggle. It improves soil fertility by fixing nitrogen, making it beneficial for surrounding plants. Its tolerance of poor conditions and value for wildlife make it an excellent choice for naturalistic or conservation-focused planting schemes.
When selecting a fast-growing tree, it’s important to think beyond just speed. Consider the eventual height and spread, as well as how much maintenance the tree will require. Fast growers often need regular pruning and can produce large amounts of leaf litter. Root systems are another critical factor, particularly in smaller gardens or near buildings.
Fast-growing trees offer a practical and rewarding way to transform a garden or landscape in a relatively short time. Whether you prioritise privacy, aesthetics, or environmental benefits, there is a suitable option for most weather conditions. The Leyland cypress provides rapid screening, Silver birch offers elegance and resilience, Hybrid poplar delivers unmatched growth speed, Weeping willow adds dramatic beauty, eucalyptus brings evergreen interest, and Common alder supports wildlife and thrives in wet areas. By carefully matching the tree to your site and needs, you can enjoy the benefits of rapid growth without compromising long-term success.
