Question
We are just starting a lawn on what was previously farmed with corn.  Have seeded and new growth.  I am letting the new growth grow.  It has seeds on the top.  How long should I wait before I cut it?  I am hoping the grass will seed itself.  Does this work?

Answer
Hi Margie;
If the grass that has the seeds on it is the grass you want, let it drop it's seeds before you mow it, then you should have a really thick lawn.
Keep watching the seed pods on the grass. You will be able to tell when they have opened and dropped their seeds.
