PROPAGATION OF MARRAM GRASS
Marram (Ammophila arenaria) is a strong growing coastal grass, used extensively throughout the temperate regions in attempts to stabilize coastal sand dunes. At present marram propagation is a wet weather job; our aim is to produce well rooted plants in tubes suitable for direct planting for dune stabilization. It grows rather like an extra strong couch grass (Agropyron repens) in that it produces long rhizomes up to 1cm thick that terminate in clusters of leafy shoots. This provided us with two types of propagation material.
- The rhizomes that can be used as:
- One to two node cuttings inserted vertically in the rooting medium.
- Cut into lengths to suit a seed tray, and laid on the rooting medium or just covered. Bud growth is rapid (2 to 3 days) and root initials show after about 5 to 7 days; development is quite rapid and well-rooted cuttings can be potted in 14 to 18 days. The longer sections of rhizome laid horizontally produce shoots from nearly every node; the shoot
