Acers, commonly known as Japanese maple trees, are beautiful and popular additions to any garden. They are known for their vibrant foliage, ranging from reds and oranges to yellows and greens, which makes them highly sought after for their aesthetic appeal. To ensure the health and longevity of your Acer trees, please follow our careful guide below.

Planting Acers

Choose a suitable location: Acer trees prefer well-drained soil and thrive best when in a sheltered area protected from hot sun and coastal winds.  They can be grown in pots or in the ground, it is up to you. Just be sure to avoid windy areas and constant hot sun as acers are prone to leaf scorch. 

 Dig a proper hole: Dig a hole that is wider and slightly shallower than the root ball of the tree. 

Enrich the soil: Mix organic matter such as compost or peat moss into the soil to improve its fertility and drainage. 

Planting depth: Place the tree in the hole, ensuring that the top of the root ball is level with the surrounding soil. Avoid planting too deeply, as it can suffocate the roots. Apply a layer of organic mulch around the base of the tree to help retain moisture and prevent weed growth. Maintain a mulch-free area around the trunk to prevent rotting.

Caring for Acers

Acers require consistent moisture, especially during the first few years after planting. Water deeply but infrequently to encourage deep root growth. Acer trees benefit from an annual application of balanced fertiliser in early spring before new growth appears. Follow the manufacturer’s instructions regarding dosage and application method.

Maintaining Acers

The best time to prune Acer trees is during late winter or early spring when they are dormant. This allows the wounds to heal before the growing season begins. Remove dead or damaged branches: Prune any dead, diseased, or broken branches to maintain the tree’s health and appearance. 

Shape and thinning: If necessary, selectively prune to shape the tree or thin out crowded branches to improve airflow and sunlight penetration. Mulch for winter insulation: In colder climates, apply a layer of mulch around the base of the tree before winter to provide insulation and protect the roots from freezing temperatures.

Seasonal Care for Acers

Acer trees are known for their stunning fall foliage. Enjoy the vibrant colours but also keep the ground clear of fallen leaves, as they can create a moist environment that promotes fungal diseases. In areas with harsh winters, protect young Acer trees from frost by wrapping the trunk with burlap or using tree wraps.

Conclusion

Acer trees can live for decades and even centuries with proper care. By following these guidelines, you can ensure that your Acer trees remain healthy, vibrant, and a joy to behold in your garden or landscape.
