The Benefits of Planting Big Trees in Autumn

Autumn is the perfect time to plant large-grade trees. As temperatures cool, the stress on newly planted trees reduces significantly. With less moisture loss through leaves and better natural soil moisture retention, trees can establish strong root systems before winter, setting them up for success in spring.

If you’re creating a new garden or looking to make an instant impact, incorporating big trees is one of the smartest investments you can make. Let’s explore why autumn is the ideal time for planting large trees, the benefits they bring, and what to consider when choosing the right species.

Why Autumn Is the Best Time to Plant Large Trees

1. Reduced Stress on Trees
   During the warmer months, newly planted trees struggle with moisture loss and heat stress. In autumn, the cooler temperatures mean less evaporation, allowing trees to establish their roots more effectively without the added stress of summer heat.
    

2. Better Soil Conditions
   Autumn’s natural rainfall helps keep the soil moist, reducing the need for constant watering. Additionally, the soil remains warm from summer, providing an optimal environment for root growth before winter dormancy.
    

3. Stronger Root Establishment
   When trees are planted in autumn, they have the entire winter season to develop a strong underground root system. By spring, they’re well-anchored and ready for a burst of growth, leading to healthier, more resilient trees in the long run.

The Benefits of Planting Large-Grade Trees

Investing in big trees for your landscape provides both immediate and long-term benefits:

1. Instant Visual Impact

Unlike small grades, which take time to establish, larger-grade trees provide immediate structure and form. When creating a new garden, the use of big trees transforms the space right from the beginning, giving a sense of maturity and design cohesion.

2. Faster Privacy & Shade

If you need privacy from neighbours or want to create a shaded retreat, large trees offer a much quicker solution than waiting for young plants to grow. Their established canopies provide immediate screening and protection from the elements.

3. Long-Term Value

Large trees have already had 5 to 10 years of professional care and maintenance before reaching your garden. With the use of a larger grade, you’re getting a tree that is already strong, well-formed, and more resilient than smaller plants—meaning the benefits justify the cost.

4. Creating a New Garden with Layers

By incorporating big trees strategically when designing a new garden, you create a layered effect that enhances the overall layout. This approach not only provides height and structure but also ensures a visual impact right from the beginning, rather than waiting years for smaller plants to grow in.

Things to Watch: Choosing the Right Tree for the Right Spot

While big trees provide many benefits, it’s important to consider your site conditions. Exposed areas with strong winds or extreme conditions may limit your species choices. However, there are still tough, resilient trees that thrive in these locations.

Top Tough Large-Grade Trees for Autumn Planting

• Pyrus Aristocrat: A hardy ornamental pear with stunning autumn colour and strong resistance to pests and diseases.
• Cornus ‘Greenvale’: A robust, fast-growing dogwood with an upright form and lush green foliage.
• Ulmus ‘Groenveld’: A fast-growing elm with a strong, upright structure, perfect for urban or rural landscapes.
• Ulmus ‘Louis Van Houtte’: A golden-leaved elm that brings a bright contrast to the garden.
• Magnolia ‘Blanchard’: An evergreen magnolia with large, glossy leaves and fragrant flowers.
• Carpinus betulus ‘Fastigiata’: A columnar hornbeam that provides excellent structure and screening in narrow spaces.
• Pyrus salicifolia: A weeping ornamental pear with silvery-grey foliage that stands out in the landscape. It’s tough, drought-tolerant once established, and works well in a range of garden styles. A great option for adding structure without being too dense.
  
   

Ensuring Your Trees Thrive

To give your trees the best chance of success, keep these key factors in mind:

• Staking: Large trees need proper support, especially in windy or exposed sites. Secure them with stakes to prevent movement while they establish.
• Mulching: Apply mulch around the base to retain moisture, regulate soil temperature, and suppress weeds - just not right up against the stem.
• Watering in Summer: Even though autumn planting gives trees a great start, they still need water through the first summer during extended dry periods. This prevents stress and ensures strong growth.
