Lawns recovering pretty well after Summer stress

I've noticed, including after this past Summer's drought period, a lot of lawns have recovered pretty well this Fall. These are lawns that have been established for years to decades. Many have a lot of Ryegrass or Tall Fescue, and these grass species are still there after years of stress despite supposedly limited dormancy recovery abilities. Some are even non-irrigated. I'm not saying everything is perfect or that none of them had to reseed areas, but overall it seems like grass tends to recover from normal Summer heat stress, regardless of the species.

I wonder if a lot of the advanced devastation that we talk about here has to do with renovations or new construction lawns that haven't hit the 5-6 year mark yet, and are less established, or lawns that weren't maintained properly.

Anyone else noticed that there are older lawns that go dormant and then largely recover, that are not just KBG, Fine Fescue, or Poa Triv (which tend to be pretty good at dormant survival), but other species as well? I remember some transition zone people talking about Tall Fescue bouncing back well in the Fall after going largely brown for a month or two in the Summer, for instance.

I think I remember listening a podcast where they showed research that once a lawn is established for 10 years that the NPK requirements of the plant go down exponentially. Unfortunately that's about all I remember but the point was the older it gets the less it needs to look good. Noticed the same thing as you around my area, most lawns went dormant this summer and started to green up again in October.

Absolutely. I even noticed the difference between my first summer after reno and the second. IMHO this all boils down to root depth.

I've also noticed that areas of the lawn that really struggle in the summer are often due to sub-surface things like compaction, rocks, concrete debris/chunks around edging/sidewalks/etc. That results in shallow roots and a struggling part of the lawn. I've fixed a few areas in my lawn by digging down a few inches and pulling out chunks of concrete/rocks. You'd be surprised how much junk/gravel/debris is covered by just a couple inches of fill dirt.

Keeping thatch in check and cleaning debris out of the lawn at least once a year makes a huge difference as well, particularly for lawns cut tall.

I know. I just pulled out a large rock or concrete hunk (couldn't tell as it was getting dark) and a cinder block from the same area last week. In this case, the buried stuff had the opposite effect: causing water to pool more. Both situations are bad.

Transition zone, TTTF, and no routine irrigation.

I only deeply watered a few times throughout the summer. That wasn't the plan but other things got in the way. My lawn looked mostly like burnt toast but it recovered well.

The most impressive part of the lawn was the most neglected area - the back yard hill. Full sun, absolutely no shade and poor moisture retention due to having a 16-18 degree slope. I mowed that slope twice at the highest setting from July to October. I repeat, twice! It barely grew for months but made it through the summer stress and didn't appear to have any die off. Blew me away. I surely thought that if one section needed reseeding, it would be there. Sometimes less is more when it comes to none irrigated lawns.

My neighbors that aren't irrigated have lot of burnt out spots (small to large in some cases). I didn't irrigate at all and the only spot that was really hurt was the one that got the most sun in the summer. Several neighbors with most damage were having their lawn cut every week during the drought so that might have exacerbated their problem. I also aerated right after the drought broke and I think that helped replenish the root zone.

I've been in this house for two seasons now - one super wet and one super dry. I'm kinda glad I've now seen both extremes so I know how it responds. Hopefully next year will be a bit more "normal" whatever that is anymore.
