Hello to all this is my first post.

I have sown some Rolawn Medallion grass on 23rd April and after 3 weeks I have noticed some gaps. When should I reseed as I want to be careful not to damage the young grass thats grown- see attached

here is a pictu

Hey,mine is exactly the same.I just assumed that i had to sprinkle more seeds after the first time mowing.(havnt tried yet,maybe tomorrow if the weathers ok).
Other than that,havn't a clue.Would also appreciate tips.

I have overseeded on day 22. Just threw the seeds on the gaps and added compost to cover buts of it. Luckily we have had lots of rain and I am due some humid periods too so the mixxture of moist and heat is great.

here is a picture for day 25. Is has thicked up for sure.
I am wondering if the gaps will be filled by the grass roots growing sideways and creating new shoots?
