Cultivation Details
Leymus multicaulis is a plant of continental temperate climates, growing in areas with cold winters and a mean annual rainfall within the range 300 - 450mm[1]. Grows best in a sunny position, though the plant is moderately shade tolerant[1]. It does well on moderately coarse or sandy to poorly drained soils[1]. It succeeds in neutral to strongly alkaline soils ranging from a pH of6.6 - 9.0, and in soils classified as strongly saline[1]. This species is known to produce fertile hybrids with Leymus triticoides[1].
Propagation
Seed - sow in autumn in situ and only just cover the seed[2]. Germination should take place in the spring. The seed coat needs to break down before the seed will germinate, so if sowing the seed in spring it needs to be mechanically scarified first. Seedlings have poor vigour, develop slowly, and compete poorly with weeds and other grasses in the first year of establishment. It is thus very important to minimize weed competition[1]. If the supply of seed is limited, it can also be sown in a cold frame. Only just cover the seed. When large enough to handle, prick the seedlings out into individual pots and plant them out in summer[PFAF] Division in spring or summer[2]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Establishment can be slow during the first year, but once established rhizomes spread rapidly[1].
