Alnus Questions

1. What is Alnus?

Alnus, also known as alder, is a genus of flowering trees and shrubs in the birch family. Alnus trees are native to temperate and cold regions of the Northern Hemisphere, but they have been introduced to many other parts of the world, including New Zealand.

2. What species of Alnus are grown in NZ?

There are several species of Alnus that are grown in New Zealand, including:

3. Where can I grow Alnus?

Alnus trees can be grown in most parts of New Zealand, but they prefer moist, well-drained soil. Alnus can tolerate a variety of soil types, but tend not to do well in soils at the extremes of wet and dry. They are hardy to frost and cool climates which also makes them applicable to most regions.

4. How do I plant an Alnus?

To plant an Alnus, choose a sunny spot with moist, well-drained soil. Dig a hole that is twice as wide as the root ball of the tree. Place the tree in the hole and backfill with soil. Firm it in gently to remove any air pockets and water the tree well. Keep watering the tree until you are satisfied it has established and no longer at risk of drying out. Putting in a stake to support the tree along with mulching around the tree with bark chips are also advised.

5. How long does it take for an Alnus tree to grow?

Alnus trees are relatively fast-growing. They can reach a height of 10-15 metres within 10 years.

6. What is the fastest growing alder tree?

Alnus jorullensis (evergreen alder) is the fastest growing of the alders. It can reach 10 m tall inside of five years, and 20 m tall inside of 10 years. Its rapid growth rate makes it perfect for shelterbelts and for screening.

7. Are alder trees deep rooted?

Alder trees are deep rooted. They have a taproot system that can grow up to 2 metres deep which makes them very good at stabilizing soil and preventing erosion. Their root system also makes them very good at taking up water and nutrients from the soil, hence they are a good choice for planting in areas with poor soils.
