Hello:
I recently seeded few bare patches in my lawn. Since the seeds were
germinating I did not mow the rest of the lawn to try & avoid damage to the
germinating grass.

Now, I find that the rest of the lawn is really overgrown & most of the
orignial grass in now sprouting seeds. I did not know whether this would be
helpful or harmful to my existing lawn.

My question is, if seeds are allowed to form on grass will they be a direct
source of additional seeds for my lawn or is allowing grass to sprout seeds
detrimental to the lawn in any way.

TIA
Maria
