Root System of Neem Tree

Roots System of Neem Tree

Neem tree roots consist of a strong Taproot System. Taproot arises from the Radicle of the germinating embryo. Morphologically it consists of one main root, also known as Primary root, arising from the base from which further root branches arises laterally or horizontally, known as Secondary and Tertiary roots. the branches of the main root, unlike other trees, are very thick and strong.

The main root of the Neem tree root system is highly rigid and grows directly downwards into the soil. This Primary root can grow twice as long as the height of its tree and absorbs good amount of water and minerals from the soil which makes the tree evergreen even in unfavourable conditions and therefore it is low maintenance.

The roots of the Neem tree increases the water holding capacity of the soil in which it is grown to a great extent and also prevents soil erosion during floods.

The root system of the Neem tree is highly extensive and therefore requires a large surface to thrive. As discussed earlier, the main root of Neem tree can grow twice as long as the height of the tree, therefore it can be harmful to the structures in proximity (buildings) to the tree as the strong roots can cause damage to them.

Hence it is important to keep a substantial distance between the tree and the buildings (at minimum 10 feet clear distance from any surface). Building underground concrete walls as barriers can also prevent the sprawling roots from reaching the nearby buildings. Also, it is not advisable to grow the Neem Tree in narrow spaces, for example, backyards.

Place of tree saplings also play a very crucial role in the healthy proliferation of the Neem tree roots and hence the tree. It is feasible to plant the tree saplings deep enough so that the roots are present far down from the soil surface and are not restricted or ceased from growing to their full potential.
