All of a sudden today I noticed this damage to my lawn. It has happened before last Summer/Autumn. What is it and how can I stop it. Photos attached.
Thank you, will do. Any way to repair the lawn-just reseed?
Looks like you have a thick layer of thatch, I'd wait a month then heavily scarify, aerate and topdress with a sandy loam. you could then reseed any bare patches.
Looks like crow damage ( looking for grubs ) to me too. Seems like there's a fair bit of damage there so I'd follow Verdun's advice to help solve the issue.
How to stop the crows.
Thanks for all the advice.
Get rid of leather jackets with nematodes, scarify lawn a little later then you will get rid of crows.
Not usually crows. Rooks. Looks like they have done you a favour!
