What are the factors that affect the growth of honey locusts?
However, they do best in rich, moist bottom lands. Other factors that can influence root development include the soil's depth and temperature, as well as the availability of water, minerals, oxygen and mycorrhizae fungi. These fungi invade tree root systems, but -- unlike many other types of fungi -- create a symbiotic relationship. The mycorrhizae network increases the tree's mineral and water uptake, while the tree provides carbohydrates to the fungi.
What are the characteristics of a tree root system?
Tree root systems, in their most basic form, are composed of a few large, permanent roots -- which provide anchorage and transportation of water and nutrients -- and smaller, temporary feeder roots and root hairs. These feeder roots provide the primary means of absorbing water and nutrients, which are mostly near the soil surface. These smaller roots serve this purpose for one or two years, after which they die or become integrated into the larger roots.
Do honey locusts have flat roots?
While honey locust roots may be somewhere in between classic tap root and heart root systems, they do not have flat root systems. Flat root systems are almost entirely near the surface. This can create problems for the tree's stability during wind storms and during events that disturb the soil. Shallow roots also create yard maintenance issues, as they can not be mowed or planted over. Common trees with flat roots include the silver and sugar maples, birch, cottonwood, fir, spruce and hackberry.
Is a honey locust a heart or a tap?
Some scientists classify the honey locust root system as a heart root system, while others classify it as a tap root system. This is understandable, as this tree's roots have characteristics of both.

Overview
The honey locust (Gleditsia triacanthos), also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys. Honey locust is highly adaptable to different environments, has been introduced worldwide, and is an aggressive, invasive species.

Cultivation and history
Its cultivars are popular ornamental plants, especially in the northern plains of North America where few other trees can survive and prosper.

Nitrogen fixation
The ability of Gleditsia to fix nitrogen is disputed. Many scientific sources state that Gleditsia does not fix nitrogen. Some support this statement with the fact that Gleditsia does not form root nodules with symbiotic bacteria, the assumption being that without nodulation, no nitrogen fixation can occur. In contrast, many popular sources, permaculture publications in particular, claim that Gleditsia does fix nitrogen but by some other mechanism.
Research
In research using databases, more than 60 phytochemicals were identified from honey locust, including polyphenols, triterpenes, sterols, and saponins, with in vitro studies assessing for possible biological activity.
