An experiment was conducted with 5 leaf stages and 3 different spacings in secondary nursery. Mortality rate was low when cardamom seedlings were transplanted from primary nursery after they attained 3-leaf stage. Plant height, number of tillers/plant and number of leaves/plant were higher when seedlings were transplanted to secondary nursery after 3 leaf stage. Number of tillers and number of leaves increased with increase in spacing in all leaf stages. Narrow spacing leads to lanky growth of seedlings. Optimum spacing in secondary nursery was 22.5 cm×2.5 cm.
