Patches on lawn

[ber77tie]

Sorry this isn't an allotment question but I wonder if anyone can help. I have some areas on me lawn which are a lighter green. Any ideas why this may be please? I've heard of leather jackets but not sure how I can tell.

Stones beneath the surface can cause problems.  They can work their way up.

Pictures for us to see please.. It's rather difficult to answer without seeing the evidence... small patches would be different to larger patches..
