Hmmmm....depends on what you are planting. I just put in iron and clay peas this last Sunday. I bet the hogs will rip it to hell in under a month with half an acre. Then I will plant rye grass and they will shred it as soon as there is any evidence of growth. The I will plant it with conrete and steel beams and it will take them just alittle more time to destroy that.

In summation: If it grows or is edible hogs will destroy it.
