We have about 5 acres of land that we need to seed . My husband has it in his head that he'll just do it by hand . My thinking is that doing it by hand you're going to waste a lot of seed b, over seeding certain spots and under seeding others . I think we should get a seed spreader . Am I just totally wrong here or is it worth getting the spreader? Now here is the next question if using a spreader is worth while . Our property isn't perfectly smooth , a little bumpy . What's the best type to use , handheld or push type ?
