Comparison of ash and rowan trees in a garden setting

As a professional gardener in Staffordshire with over 15 years of experience, I often get asked about the best trees to plant in UK gardens. Two popular choices, especially here in the Midlands, are the ash and rowan trees. Both have their unique advantages, but which one is right for your garden? Let’s dive in and find out.

Quick Answer

If you're looking for a hardy tree with year-round interest and vibrant berries, go for rowan. Opt for ash if you prefer a fast-growing tree with excellent shade coverage.

Choosing the Right Tree for Your Garden

Climate and Soil Conditions

In the UK, particularly in the Midlands, our climate can be quite varied. Both ash and rowan trees are well-suited to our temperate climate, but they have slightly different soil preferences. Ash trees prefer moist, well-drained soils, while rowans are more forgiving and can thrive in poorer, rocky soils.

Growth and Maintenance

Ash trees are known for their rapid growth, reaching heights of 20-35 metres. This makes them ideal for those looking to create a shaded area quickly. However, they do require regular maintenance to manage their size and prevent disease.

Rowan trees, on the other hand, are smaller, typically growing to 10-15 metres. They require less maintenance and are resistant to many common pests and diseases, making them a lower-maintenance choice for smaller gardens.

Benefits of Each Tree

  • Rowan trees produce beautiful clusters of red, orange, or white berries, attracting birds and wildlife.
  • Ash trees provide excellent shade and are fast-growing.
  • Both trees have attractive foliage that offers seasonal interest.

Practical Planting Tips

When planting either tree, it's best to do so in the autumn or early spring when the ground is not frozen. Ensure you dig a hole twice the width of the root ball and the same depth. Add some well-rotted manure or compost to encourage healthy growth.

For rowans, consider planting them in a spot where you can enjoy their autumn display. Ash trees, due to their larger size, are better suited to the back of a garden or as a focal point.

Conclusion

Ultimately, the decision between ash and rowan will depend on your specific garden needs and aesthetic preferences. Both trees have their unique charm and benefits. If you’re in Staffordshire and need further advice, feel free to reach out. Happy planting!
