What type of soil do you have in Long Beach?



Below 1-2 inches, it's hard-packed clay in this particular spot.

This was just an idea. Water won't penetrate it.



Grass roots don't really grow much below 2" anyways. Just look at

rolls of sod. They certainly don't come 2" thick (with soil).



Rolls of sod are sold with only enough soil/roots to survive till thet're layed.

That's for sure. It has nothing to do with how deep grass roots actually
grow and clearly the poster is clueless about turf.



Otherwise, the sod farms would quickly run out of soil.



I recently cut up a bunch of lawn for a garden with a rented sod cutter. I cut

2+" deep, and still had a tough layer of roots that my old rototiller couldn't

easily get through. There was at least 2" of root left, and I had to break it up

with a shovel before my tiller could do its job.



Of course, since you operate by the stupid theory that you have to water every

day if it gets over 80F (in another post), your grass will have no deep roots.


Agree. Watering about twice a week, 1/2" at least 1/2" at a time, if
it hasn't been raining is a good compromise. Shallow watering every day
is bad practice and a waste of water.



They only go deep if they have to to find water. My lawn has no problem with a

good watering once a week in 80F weather.
