Planting & Growing
Frontier Elm will grow to be about 25 feet tall at maturity, with a spread of 15 feet. It has a high canopy with a typical clearance of 7 feet from the ground, and is suitable for planting under power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for 90 years or more.
This tree should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by cuttings, however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
