A hardy, fast-growing natural hybrid, it thrives on a variety of soils, and sites are commonly planted in gardens to provide a quick boundary or shelter hedge, because of their rapid growth. Although widely used for screening, it has not been planted ...
Though the roots may reach depths of 1.2 to 1.8 metres (4 to 6 ft) 70% of their mass is in the top 15 centimetres (6 in) of the soil and 81% in the top 30 centimetres (12 in). [7] The main roots grow almost directly downward with only very short side roots and very little or no branching.
Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted. Layering is utilized by horticulturists to propagate desirable plants.
Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant. [22] Examples of stem tubers are potatoes and yams and examples of root tubers are sweet potatoes and ...

Designs of containers for raising planting stock have been many and various. Containerized white spruce stock is now the norm.
Hydrotropism requires a root to bend from a drier to a wetter soil zone. Roots require water to grow so roots that happen to be in moist soil will grow and branch much more than those in dry soil. Roots cannot sense water inside intact pipes via hydrotropism and break the pipes to obtain the water.
