We just had out first raucous all night spring celebration on our 5 mo. old fescue from sod lawn that is on the cheap and lazy organic program (even if its origins in Hollister probably were not). As much as I insisted the rebel rousers not move from their assigned furniture, They danced upon my lawn. there are trails to the beer cooler, the hot tub, the houses. Yellowing imprints where couples were found embracing one another in the morning. I think the beer, wine and whiskeys spilled, as well as the pee was organic and will nourish the lawn. To the point. We do have a high impact area, which some would argue to pave over. I'm very happy so far with my turf situation. I even put a heat shield under my smaller portable firepit and it worked. (It was a seldom used pizza stone fit perfecty with an air gap no lawn burn!I wont have to put brick down in one fixed spot, but can move it around) I'm wondering about overseeding with purpose, say come fall throwng in some hard fescue or tall fescue which is purportedly more traffic resistant. Maybe astro turf seed. I understand from other threads why this is,in general, unwise. Takes things your existing lawn wants. Not a good option to displace weeds My purpose would be to hearty up the lawn a bit. Truth is I'm probably fine with what I have. I may install a few of those open blocks that allow plants to grow through in the impact zones. I'm wondering if overseeding can be used for other purposes. Say you have a thirsty lawn, throw in a drought tolerent variety at the right time in place to "convert" it versus pulling out what you got. Seems cheaper and lazier. Like I posted in the other topic, I dont really get the pluses and minuses of mixes in the 1st place. Should be called seeding-over. over as a prefix usually means "to much of". Alas it is not so: overseeding . Weird.
The environment that the new seed needs is the same environment to make weed seeds and your existing lawn go nuts and smother whatever seed you are trying to start. This is one of many reasons I'm not a big fan of overseeding.
If you have bare patches, then seeding would be a good idea. But that isn't quite the same as "overseeding".
