Cultivation.--Balm is readily propagated by means of divisions,

layers, cuttings, and by its seeds, which germinate fairly well even

when four years old. Owing to its small size, the seed should be planted

be controlled. The soil should be made very fine and friable, the thinly

scattered seeds merely pressed upon the surface with a block or a brick,

and water applied preferably through the bottom of the seedpan, which

may be set in a shallow dish of water until the surface of the soil
