Planting & Growing

Navajo Thornless Blackberry will grow to be about 5 feet tall at maturity, with a spread of 4 feet. It tends to be a little leggy, with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years. This is a self-pollinating variety, so it doesn't require a second plant nearby to set fruit.

This shrub may not always play well with others; as such, it is best grown in its own designated garden space or isolated area of an edibles garden. It should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
