If I use Roundup (will this endanger bordering hedges and shrubs?),
should I add new topsoil directly on the dead grass, or first till?


I wouldn't leave it all winter without planting something, and that
something may as well be grass. You risk erosion if you leave it bare and I
can't think of any positive things that will come from a bare lawn. No
matter what you do, you will end up with some weeds. I'm not sure you need
to go down 8 inches, but its your lawn. I would kill off the grass with
Roundup, correct the grade, cultivate the surface slightly, seed, cover, and
keep moist. Fall is a good time in most areas, so you can start the prep in
late summer. Next spring, be sure to apply some pre-emergent herbicide
because there will be weed seeds that will germinate otherwise.

You have no plans to plant anything even remotely edible on our near the
treated area in the future, right?

Roundup has to be applied to growing, green parts of plants to kill them.
If you spray the leaves of the hedge, it will probably kill the leaves and
MIGHT kill the hedge. Therefore, you have to be careful not to spray on
windy days and you have to be careful. I would shield the hedge with some
cardboard if there is a question. I won't kill things by from soil contact.
Always read the directions before using garden chemicals I would till the
entire area and rake to remove large clumps and stones. Then I would add
soil and level. You can LIGHTLY roll the area and then seed. As someone
mentioned, you can rent a sod cutter to removed the existing lawn and that
will eliminate the need for chemicals.

I've got a lawn, about 50' x 70'. It's more than half weeds, despite
several years of half-hearted spraying and picking. The grade is
wrong; it slopes to the middle of the yard.

So basically I want to start anew. My intended course of action is to
flip over the lawn (after the fall) by shovel to a depth of 8" (so
that no weeds return). Then bring in topsoil and grade. Leave over the
winter for further settling. In the spring, fix any holes caused by
settling and then seed.

Wow. Turning over 3500 square feet with a shovel sounds like an awful
lot of work just to make sure that weeds are gone. You could just as
easily
use the chemical of your choice to kill everything, water for a week to
see
if any seeds come up, then take care of that. Then add the topsoil,
prepare, and plant.

Don't get me wrong, if you want your yard tilled, by all means, till
it -
but if it were me, I'd at least rent a tiller, I wouldn't do it with the
shovel!

Agreed, except for the watering part. No matter what, there will be weed
seeds germinate.

I think you'll be badly disappointed in the results. Depending on your
feeling about glyphosate vs. organic solutions, what I'd do is nuke the
current lawn, either with a Roundup clone or by solarizing. The solarization,
if done properly, will reduce the number of viable weed seeds in the soil,
while the Roundup or similar won't.

Hire someone with the proper equipment to till and regrade this fall, then
reseed promptly. You don't want to leave the soil uncovered for the winter,
and fall is the best time to replant grass in most of North America. By late
spring, you should have a fairly thick lawn, ready for first mowing.

Hello all,

I've got a lawn, about 50' x 70'. It's more than half weeds, despite
several years of half-hearted spraying and picking. The grade is
wrong; it slopes to the middle of the yard.

So basically I want to start anew. My intended course of action is to

This is a major project, so I would really appreciate any suggestions.
