How we graze our pastures, though, does not affect the basic growth processes of the grasses. If we severely graze a pasture short, plants in that pasture need extra time to recover before they are grazed again. Warm-season grasses are particularly sensitive to recovery periods that are too short. This is true regardless of whether the plants are in a continuously grazed pasture or the plants are separated into many rotationally grazed paddocks.
Recovery time is particularly important as we approach winter, especially for warm-season grasses, and even more so if they are still recovering from drought. Plants grazed earlier this year may not have started to recover until they received rain. Severe grazing now, before they have fully recovered from their summer stress, will weaken plants as they go into winter. Most plants probably will survive, but next spring they will green-up later, early growth will be slow, and they'll compete poorly with weeds. So as we approach winter, “take half and leave half” still is a good management technique. It helps assure that your pastures will be healthy and grow vigorously again next year.
