Abstract: The four <i>Ficus</i> species, viz. <i>Ficus</i> <i>racemosa</i> Linn. (Cluster fig), <i>Ficus</i> <i>microcarpa</i> Linn.f. (Chinese or Malayan banyan), <i>Ficus</i> <i>religiosa</i> Linn. (Peepal tree) and <i>Ficus</i> <i>benghalensis</i> Linn. (Banyan tree) belonging to the ‘<i>Nalpamara’</i> group of medicinal trees possess immense medicinal values. The barks of these four <i>Ficus</i> species make a unique formulation to cure various uterine problems in women. Germination percentages of seeds of <i>F. racemosa</i>, <i>F. microcarpa, F. religiosa </i>and<i> F. benghalensis</i> are reported to be 5.0, 2.3, 27.7 and 82.0%, respectively. Therefore, studies were undertaken to standardise and compare various propagation methods for these species. Various seed treatments showed improvement in germination percentage. In <i>F. racemosa </i>and <i>F. microcarpa</i> there was drastic decrease in seed viability after six months. In <i>F. religiosa </i>viability started declining only after 12 months whereas <i>F. benghalensis</i> seeds retained satisfactory germination even after 18 months. Studies on vegetative propagation showed that all the four species showed poor rooting of stem cuttings. The percentage success of rooting was 10-12% in <i>F. racemosa</i> and <i>F. religiosa</i> and 18-20% in <i>F. microcarpa</i> and <i>F. benghalensis</i>. Air layering was found very successful in all the four species and the percentage success achieved was 80-90%. In <i>F. racemosa</i> success rate during May-June was only 40% whereas it was 90% during August–September.
