Grazing Reed Canarygrass
Reed canarygrass produces high yields and grows very well in wetlands. It also grows well in well-drained soils. It would be one of our most popular pasture grasses if it wasn’t so hard to graze due to problems it has with a lack of palatability.
Reed canarygrass has two things working against it. First, it naturally contains some unpalatable compounds called alkaloids that discourage animals from eating it. In addition, the plant produces a course stem that makes it difficult to eat.
If you have reed canarygrass pasture, the only way I have found to use it effectively is to always graze it before it gets very tall. Ideally, this means that when the grass gets eight to ten inches tall, and no taller, immediately graze it down to three or four inches in just a couple of days and then move off to another grazing area. When it regrows back to eight to ten inches tall, graze it again. Every time it regrows, graze it again and again.
During fast growth in spring, you may need to graze the same area every two or three weeks. This takes some dedication and intensive management. If the grass has gotten away from you this year, animals will just nibble at some leaves. Now you would be better off cutting the taller growth for hay and then renewing your intensive grazing as regrowth begins.
Reed canarygrass is not as bad a pasture grass as many people think. But it does take some knowledge about the plant and some dedicated management to get good use from it.
