Our lawn is in a dreadful state and it's mainly due to a black and white pest that appeared last year. Jilly loves to dig holes and she seems determined to rid the lawn of grass. Over the past year the garden has become quite hazardous and the grass is almost impossible to mow. I was wondering if anyone has used any kind of mesh under their lawn to stop pets from digging. I know you can get grass reinforcement mesh but it's horrendously expensive. Would ordinary fencing mesh do and how deep would it need to be? The whole lawn needs to be dug and levelled and returfed.
