weeds, 99.997% kill in 60 days</DIV>
<DIV><BR></DIV>

<P>Dear All,</P>
<P>Update on the Arastradero poppy project, that you can see at <A
href="http://www.ecoseeds.com/arastradero.html">http://www.ecoseeds.com/arastradero.html</A>
happening here in the Palo Alto, California hills.</P>
<P>Starting Phase 2, and found that about one pound of weed straw per square
foot, harvested after the seeds have shed, will kill all of the annual weed
seedlings between October and December 31. Then you have a clean
spot to plant the natives from January 1 to February. </P>
<P>A few dormant straggler weed seedlings will come up periodically, but it is
a lot better than the 2,000 weed seedlings per square foot that were coming up
before the weed straw treatment.</P>
<P>In California, instead of cutting and removing the weed straw from a site,
which is how weeding has been done for decades, I am suggesting that you wait
for the seeds to drop, and then use the straw to kill the next generation of
seedlings. I look at hillsides of wild oats and thistles as 24K gold
now, free weed killers.</P>
<P>It is about a 5 to 1 ratio in terms of area of straw that needs to be cut,
to cover an area to kill the seedlings. Hope this is useful to those of
us who have wall-to-wall annual weed seedlings to manage, like California, the
Great Basin, etc.</P>
<P>Since my project is in a city preserve, and located right next to the
parking lot, everyone is invited to come and view the results, if you are ever
in the area. </P>
<P>Sincerely, Craig Dremann (650) 325-7333</P>
