Hi all,
I’m a complete novice when it comes to lawn/grass care so I’m looks for some tips or advice on repairing my lawn.
I’ve lived in this place for over a year and kept the lawn very green and tidy. However the past month – two months it’s started drying out and dying in areas and I’m not sure how to stop it or bring it back.
I’m assuming it needs a dethatch and some thing else?
Any advice or tips would be greatly appreciated.

Dethatching is a recent trend in lawn care that’s become more common thanks to youtube creators and other non-academic sources. As such, there’s a widespread misunderstanding/misinformation about the topic. This automatic comment has been created in the hopes of correcting some of those falsehoods.
Thatch is the layer of stems and roots, both living and dead, that makes up the top layer of soil. Grass clippings are not thatch and do not contribute to thatch. The thickness of thatch can only be assessed by digging into the soil.
Some thatch is good. While some academic sources say that under 1 inch of thatch is beneficial, most settle for half an inch. Thatch is beneficial for many reasons (weed prevention, traffic tolerance, insulation against high temps and moisture loss, etc) and should not be removed. Over half an inch of thatch may not warrant removal, but the underlying causes should be addressed. An inch or more of thatch SHOULD be addressed. Dethatching as a regular maintenance task, and not to address an actual thatch problem, is NOT beneficial… Again, some thatch is good.
Thatch problems are not typical. Excessive thatch is a symptom of other issues, such as: over-fertilization, overwatering, regular use of fungicides, excessive use of certain insecticides, high/low pH, and the presence of certain grasses (particularly weedy grasses).
Dethatching with a flexible tine dethatcher (like a sunjoe) causes considerable short-term and long-term injury to lawns, and is known to encourage the spread of some grassy weeds like bentgrass, poa annua, poa trivialis, bermuda, nimblewill etc. In some RARE cases, that level of destruction may be warranted… But it must be done with great care and attention.
A far less damaging alternative to dealing with excessive thatch is core aeration. Core aeration doesn’t remove a significant amount of thatch, and therefore doesn’t remove a significant amount of healthy grass. BUT it can greatly speed up the natural decomposition of thatch.
Verticutters and scarifiers are also less damaging than flexible tine dethatchers.
For the purposes of overseeding, some less destructive alternatives would be slit seeding, scarifying, manual raking, or a tool like a Garden Weasel. Be sure to check out the seeding guide [here.](https://www.reddit.com/r/lawncare/s/pUsKCxyvwQ)
Additionally, be sure to check the list of causes above to be sure you aren’t guilty of those.

My lawn used to look like this when i forgot to turn on the irrigation for a month. Lots of water, like 10mm 5 times a week and a good fertiliser brought it back. It took about 2-3 weeks of watering to get to this point. The soil compaction test with the screwdriver found that it was solid and is completely fine after the 2nd week.
