As a gardening and landscaping expert, I have come across the issue of black alder being reported as an invasive species on certain soil types. This means that it has the potential to spread and take over areas where it is not wanted, which can be detrimental to the local ecosystem.
When it comes to choosing trees for a landscape or as a specimen tree, it is important to consider the potential invasiveness of the species. While black alder may have some positive features, such as its ability to tolerate wet soils and its attractive foliage, it is not recommended to plant it widely in these roles.
In my personal experience, I have seen instances where black alder has spread aggressively and outcompeted native plants in certain areas. This can disrupt the balance of the ecosystem and negatively impact biodiversity. Therefore, it is important to exercise caution when considering black alder for planting.
It is worth noting that the invasiveness of black alder can vary depending on the soil type. In some soil conditions, it may not exhibit invasive tendencies and can be a suitable choice. However, it is always wise to consult with local gardening experts or extension services to determine if black alder is considered invasive in your particular area.
To summarize, while black alder may have some desirable characteristics, its reported invasiveness on certain soil types should be a cause for concern. It is best to avoid planting it widely as a landscape or specimen tree, especially in areas where it is known to be invasive. Consulting with local experts can provide valuable insight into the suitability of black alder for your specific location.
