Nitrogen-fixing trees can boost the growth and productivity of everything else in your landscape by converting atmospheric nitrogen into forms plants can use. Synthetic nitrogen fertilizers have a significant environmental footprint and we can expect them to only get more expensive. To completely remove the need to bring in nitrogen from off site while maintaining high productivity, a considerable area needs to be dedicated to nitrogen fixing plants. Abundant scotch broom or red alder, both being nitrogen fixers, are likely indicating the need for more available nitrogen in your landscape.
Paulownia, also called empress tree or princess tree, is an exceptionally fast growing hardwood and nitrogen fixer. It also has beautiful summer blooms. It is only marginally cold hardy for us in Merville, although we have a neighbour with a large well established tree. Protection from any cold snaps in their first few years is a good idea.
Black Locust is very hardy and is one of the fastest growing trees on our farm. These trees have little thorns so gloves are recommended for planting!
This year we have 'Nyirségi' Black Locust which has been specially selected for fast straight growth, making them ideal for timber or posts. The seem to have grown as much as 15% more than the ‘normal’ black locust this year.
We are also offering thornless honey locust for the first time. These are beautiful and fairly common shade trees that have long interesting seed pods and very nice yellow fall colors.
