Reliance Peach will grow to be about 20 feet tall at maturity, with a spread of 25 feet. It has a low canopy with a typical clearance of 3 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more. While it is considered to be somewhat self-pollinating, it tends to set heavier quantities of fruit with a different variety of the same species growing nearby.
This tree is typically grown in a designated area of the yard because of its mature size and spread. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. This is a selected variety of a species not originally from North America.
