Why is my grass growing better in patches

Please any ideas how to fix this problem with my grass.. Thanks Scott

 

Have you got a dog?

 

Yes i have mate.

 

Next question, bitch or dog?

 

Dog. I have rocks in his water. He seems to urinate on the long grass. Light patches are old stains which im going to sort out. Its just the different growths im worried about..

 

Got a feeling the urine is fertilizing the grass, the rest of the grass is starved.
You need to mow it regularly, that would help the overall appearance, and some feed for the yellow part wouldn't go amiss, then between the two of you it would be green all over.

 

Cheers mate. Thanks for ur help....

 

Ok , no problem.

 

Sorry to jump on your post, I also having same problems I have a bitch and assumed that the wee would kill the lawn not fertilise it I have over seeded the entire lawn 11 days ago to try and regain an even colour. Attached photos show the patches clearly.
Any help advice greatly appreciated
I have manually aerated entire lawn prior to seeding.

 

You also find the urine acts as a fertiliser during the winter and wet periods ,or if you water the lawn frequently .
During dry weather the areas get the urine in a much stronger dose with no dilution, so actually burning the grass.

 

This makes sense as I have watered the garden alot over the last few weeks whilst preparing the soil etc and watering in the grass seed.

Just never realised that dog wee could stimulate growth

The green areas generally have no brown patches just tuffs of nice healthy, very quick growing grass. Just wish it was all over lol.

Is there a reason why although regularly watered there are vast areas of the lawn barely growing at all, grass see is all less than 2 years old as per image attached and over seeded twice since planting.

Alot of the lawn is now going to seed as I am unable to cut due to the seed being down ‍♂️ lawn looks awful.

 

No brown in centre just rings of lush grass lol

Grass doesn't look so bad if kept short, just irritating that when I cut I only seem to be cutting 50% off the lawn, as the rest seems dormant.

Hence the overseed that I am hoping will pull through in the next week or so

 

Well I think you need to feed the areas which are not growing.

 

Thanks mate I will do as soon as I am able to assuming now I have to wait for seedlings to establish prior to feeding?
I do have a pre seed fertilizer 6 - 9 - 6 do you think that it will do any harm to pop some of this over lawn as grass is showing signs of growth or is this a no no, I have read mixed opinions?
Cant see it doing any harm myself, just wandered your opinion.

Once established will apply a spring summer fertiliser to those areas struggling.
