'Paul',

In what way does it become uneven? Is it because of worm activity?

I have a lawn which is approx. 4 years. This has been a great success,
self seeding, hard wearing etc. However, every spring the lawn becomes
uneven, so is it safe to assume that it requires rolling and when
would be the best time?
