I just planted 3 acres and protected 2.5 of them with the plot saver so I will see how good it works and will report back on it. We have at least 70 deer per sq mile here may be more and we could never get anything established before the winter because there is very little else for them to eat. I planted mossy oak bio logic premium perennial. I planted this plot on aug 8th and will leave it up until the 1st or 2nd week of oct. We do put out cages to monitor use in all the plots and we have tryed everthing else but after they get used to the other scare tactics usually in 2 to 3 weeks they eat it to the ground I have even seen the deer trying to push over the cages.
