 |
|
I'm new here, but from the group name, it seems to be the place for this.
We recently bought a home in rural Southern Utah. Zone 10. It is basically
sand dunes on top of lava caps and caliche.
Our back yard is a rolling sand dune. We got the irrigation water system
working this past summer, and what a mistake! I now have lots and lots of
cockleburs. Little spiky spheres about 1/4" in diameter. I went out and
sprayed Roundup on them and the other weeds and grasses I wanted to kill,
but it only killed about half of them. I took a large propane weed burner
to the rest of them. Some burned down, but some still have green centers
that lived.
I have since removed all Rain Bird Maxi Paw sprinklers. I have sprayed with
Roundup, and got the big concentrate bottle so I can spray more during this
winter. At the end, I will burn it again, and have my BIL come in with his
tractor rototiller to turn it over so I can rake out the roots. Maybe some
of the eight billion cockleburs will bury in the soil and not germinate due
to the Roundup.
Is this the logical approach? Suggestions which would be easier or better.
When finished, we'll coutour the yard, place retaining wall, reinstall the
sprinklers, and start from scratch. I just don't want a lot of weeds
sprouting through the new grass.
It's probably going to be constant war trying to keep the windblown seeds
and bird borne seeds from getting hold in the new grass.

No. Glyphosate kills by contact *only*. It has no residual herbicidal
properties, or pre-emergent properties, whatsoever.
And, churning up the ground with a tiller will probably just bring more
seeds to the surface, where they can germinate. "Cockleburr" is a common
name, usually describing Xanthium spinosum L. It's an annual, so 'raking
out the roots' would be a waste of time.

Also, Roundup has to be applied at higher concentrations to kill tough
weeds. 2% will kill the easy ones, 6% is much more effective. And it
may take 2 applications in some cases. It will kill the whole plant,
so no need to dig out roots of anything.
If you're trying to establish a lawn in a sand dune, you're going to
need topsoil to either mix in or cover the sand. If you cover it with
topsoil, that should keep most of the weed seeds from sprouting. I
guess the real question here is if a traditional lawn is what you
really want for that type of environment, or if you'r better of
landscaping with plants that are suited to what's already there. |
