I laid my turf a week ago and I\'m watering it twice daily as its quite warm but it still looks like in certain spots it\'s dying so please somebody help me
Unfortunately, laying anything during the more extreme parts of the year can yield results like this. Watering will be a very delicate balance. You want the roots to remain slightly moist, but do not want them wet. This invites rot and root suffocation.
By autumn, you will likely know what repair needs to be done. Until then, offering proper moisture content, and letting it dry very slightly between watering will be necessary. Adding shade cloths in those spots may help, if you feel that this could be sun related.

Generally, this will be about 2 1/2 inches, leaving it a little longer at 3 inches during the heat of summer.

It's quite a large area and I've hand cleared it 3 times already but they keep on coming up.
Yes, I would start to spray so that it will, at least, be more manageable for your new grass to emerge. Products containing the chemical, Glyphosate, are fast acting (within a week) and breaks down on contact with soil through a process called microbial degradation.

We don't recommend brands, but you can find pH test kits at garden centers and plant nurseries. Your local extension service also will provide testing.

We are replacing our grass and our contractor wants us to use roundup. I would like a safer non-toxic method that is safer for people and animals. So far, we've not been successful. Is there a method/product you recommend?
Killing grass without chemicals can take time and you may not get all the roots. The best way is by solarization, covering the area with clear plastic during the hottest part of the year and letting it cook the grass. (The article below says black plastic, but clear plastic is now recommended.)

The use of glyphosate should be safe if the directions are followed exactly, and you take precautions as outlined to wear gloves, shoes, long sleeves and pants, etc. Never use it on a windy day or the product could drift onto neighboring plants. If you have Bermudagrass, glyphosate is the best way to go.
