This will be the final update and mow (although I might mow on the highest setting to chop up the leaves) until the grass starts growing faster in Spring 2015.
The front lawn which I just scarified and overseeded isn't looking half as good as the back lawn which had the additional benefit of almost 2 tonnes of compost. I'm beginning to see worm casts again too which I hadn't seen prior to the top dress. Whilst mowing it's clear that there are lots of bumps and hollows where there are different layers of compost and the seeds have germinated higher up or lower down. I'm not sure if on an informal lawn like this it matters much but it could lead to certain areas drying out more quickly than others come summer. But we'll see.
All in all, it looks very green and that's what my dad wanted.
