HYDROSEEDING VS. SOD
1. Sod is a good solution when one desires a great looking lawn immediately; however, it is generally about five times more expensive than hydroseeding. Hydroseeding will often produce turf that looks as good as sod within a very short time at a significant cost savings.
2. When hydroseeding the seed will germinate on your soil. Sod is grown on different soil and planted in your yard, which can cause a compatibility problem. This is called “not taking.” If you have ever seen sod that looks like it could be rolled right back up even months after it was planted this is an example of sod that did not take.
3. With sod the roots are chopped off resulting in a less healthy plant
4. With sod it is important to have sod installed by someone who has a lot of experience. Sod will shrink over the first month and if it is not installed properly gaps will open up between the sod rows.
