Nitrogen is a vital nutrient for plant growth and although about 78% of the earth’s atmosphere is nitrogen, most plants cannot utilise this. The majority of nitrogen is provided in the form of industrially produced fertilizers. Nitrogen fixing plants, on the other hand, are hugely beneficial in any ecosystem because they have the ability to transform nitrogen from the air into the soil. When their leaves fall and their roots die, the excess nitrogen is released back into the soil where it is picked up by other plants in the area and utilized for their own growth. The plants are also capable of growing in poor soils and improving them through their nitrogen fixation. In this way various trees and plants growing next to each other (including the nitrogen fixers playing their unique role), can thrive in harmony. This benefits the plants themselves, but also the soil, microbes, insects and animals, and last but not least- us humans. PERMACULTURE is a fairly new term applied to this really old concept.

(Gleditsia triancanthos var. inermas)
Honeylocust has feathery, green, fern-like foliage and an open growing habit, allowing sunlight to filter through, making it good for 'two-storey' agriculture. It is one of the nitrogen fixing trees that Stefan Sobkowiak of Quebec, uses in his permaculture orchard (the renowned Miracle Farm). He also uses them for living trellis posts – planting grapes and kiwis beside the tree. Wondrously fragrant spring flowers attract bees and pollinator insects. Seed pods can be used for animal fodder. Fast growing and very hardy, honey locust will grow practically anywhere even in very wet conditions making it useful for erosion control, urban settings or remediation sites. Mature trees can reach 18m (60').

Pollenator definitions
Some trees and many berry plants are SELF-FERTILE ̶means the insect pollinators or even the wind can pollinate the blossoms without the need of a second tree.
NEEDS A POLLENIZER ̶ means another tree of the same type or kind but a different variety must be blooming nearby at the same time.
EXAMPLE A Liberty apple and a Wealthy apple can cross-pollinate. Two trees of the same variety ie: ̶ 2 Wealthy apples, cannot cross pollinate because they are genetically identical.
Other trees are marked as SEMI-FERTILE. These will set fruit without a second tree. However they will often bear more, and sometimes larger fruit if another variety of the same kind of tree is nearby.
You can select 2 different trees of the same kind marked as NEEDS A POLLENIZER or plant one of those along with one SELF-FERTILE or one SEMI-FERTILE. Also consider ripening times ̶ a Goldrush apple might not start blooming before a Pristine is finished.
