Somerset lawn

After watching YouTube videos I have seeded a lawn for a new build that started off as a building site. The seed has taken really well and im sure after a follow up of overseed the patches will be gone and I will have a lush green lawn. All products arrived in a timely manner and I’m very pleased so far

Seed front lawn

If we did not have the persistent dry spell which forced me to delay the seeding I think I would have a decent lawn at the minute. I had to empty 6 large water butts to water the area. As things happened my lawn is 80% covered due to the colder weather we now have slowing or stopping the growth.
What is there looks great and I have enough seed to left to cover the bare areas in the spring so not all is lost. What has grown looks good so no complaints. Just wish we had more rain.

After treating the mostly weed lawn in May I managed to kill almost all of the grass
I have heavy clay soil which turns into a swamp after it rains. After using a hollow tine aerator and adding some sand, I reseeded with Clay King at the start of July. Copious watering before going on a weeks holiday and the result speaks for itself. Whilst everyone I knows grass had turned yellow, I had lush green, despite the infrequently watering.
2 weeks ago I overseeded again to go over the patches, I watered it once, but due to the dew and the volume of rain we have had, I'm back to a swamp. But it's now a lush green swamp
