Choosing the right tree for your garden can transform your outdoor space. As someone who has spent over 15 years nurturing gardens across Staffordshire, I often get asked about the best trees to plant. Today, I'll be comparing two popular choices: the alder and the rowan. Both have unique qualities, but which one is the right fit for your garden?

Quick Answer

If you're in the Midlands and need a fast-growing tree for wet soil, go for the alder. If you want a tree with vibrant berries and stunning autumn colour, choose the rowan.

Understanding the Alder

The alder is a hardy tree, well-suited to the wetter soils often found in Staffordshire. It thrives in areas that other trees might struggle with, such as riverbanks or marshy ground. Alders grow quickly, reaching heights of up to 20 metres, making them a great choice for providing shade and shelter.

Pros of Planting Alder

  • Fast growth rate
  • Excellent for wet and poor soils
  • Provides habitat for wildlife

The Appeal of Rowan

Rowan trees, also known as mountain ash, are beloved for their aesthetic appeal. They produce clusters of white flowers in the spring, followed by bright red berries in the autumn. These berries are not only beautiful but also attract a wide range of birds.

Benefits of Rowan

  • Stunning autumn colours
  • Attracts wildlife with its berries
  • Adaptable to various soil types

Planting Tips for Success

Regardless of whether you choose alder or rowan, planting technique is crucial. Ensure you dig a hole twice the width of the root ball and plant at the same depth the tree was growing at in the nursery. Water thoroughly after planting and mulch generously to retain moisture.

In the Midlands, the best time to plant is during the dormant season, from November to March. This allows the tree to establish its roots before the growing season begins.

Frequently Asked Questions

Can I plant alder and rowan together?

How do I maintain these trees?

Prune young trees to shape them and remove any dead or crossing branches. Regularly check for pests and diseases, especially if conditions are wet.

Which tree is better for attracting wildlife?

Rowan trees are typically better for attracting wildlife, thanks to their berries which are a food source for birds.
