In 1955, the University of Puerto Rico received planting material from Florida and established plantings in the central-western mountains of that island. In Florida, some interest was still alive in 1965, but early enthusiasm waned as homeowners neglected their raspberry bushes, growth became too rampant, picking more and more difficult among the tangle of thorny canes, and birds competed eagerly for the crop. Many plantings were destroyed, and few remain. Soil In Florida, the plant flourishes on limestone or acid sand. In Puerto Rico it is grown on lateritic Alonso clay with a pH of 5.0.
Good drainage is essential.
Germination can be expedited by pre-treatment with concentrated sulphuric acid. Stem cuttings root well, but the preferred method of propagation is by tip-layering. They develop plentiful roots in 3 to 4 weeks. As the canes grow, they are loosely tied to the stakes and wires. A mulch is desirable to retain Moisture and control weeds.
