How soon will it grow back?
Vegetation control is always a process and cannot be viewed as a single project. Repeated applications are required no matter what form of control you use--herbicide, machines, or goats. Residual seed, banked in the soil, will return to grow again. However, goats often create a long-term net gain in restoring healthy soils and native vegetation. With proper timing, they reduce the amount of seed released into the soil and surrounding areas, which helps deplete the seed bank and control spreading. The number of applications and amount of time for this depends on the vegetation species, the time of year the property is grazed, and the overall health of the soil (weeds and invasives are often the strongest competitors on depleted soils).
