Prosopis species hybridize readily and are difficult to distinguish, common names are often confused in nursery specimens
Prosopis sp. respond to water with fast, lush top growth. However this may not be balanced by adequate root growth and so trees are prone to blow over. Water deeply, wide, infrequently and moderately to prevent the problem.
