Dried seeds become dormant and are notably difficult to germinate and therefore require extra measures to grow. Dried seeds should be initially immersed in warm water (40°C or 105°F ) and then let soak for 1 day. Seeds should be wrapped in a moist cloth, placed in a sealed glass jar and kept in the refrigerator for 2 - 3 months. After refrigeration, soak the seeds again in warm water overnight. Plant the seeds about 1 cm deep in a loose well drained soil media. Young caper plants can be grown in a greenhouse (preferable minimum temperature of 10°C or 50°F).
Stem Cuttings:
Collect cuttings in February, March or April. Use stems from the basal portions, greater than 1 cm diameter and 8 cm in length with 6-10 buds. Use a loose well drained media with bottom heat. A dip in a IBA solution of 1.5 to 3.0 ppm is recommended (15 seconds). A 70% rooting percentage would be considered good.
