<p>Hi Craig</p>
<p>Putting soil in pots changes the entire ecology of the experiment. I hate it when people do pot studies on plants that are growing in natural settings and try to extrapolate that data into the real world. Your plants most likely died from damping off, a
common complex of fungal pathogens that is most virulent in containers and much less so in the real world.

<p>Dear All,</p>

>From my Poppy Project in Palo Alto, California, (Google = Poppy Project+Arastradero) I took soil samples from under the poppies where they had been shedding seeds this summer from locations 10 feet apart, and put the soil into 4 inch plastic pots. </div>
<div style="FONT-SIZE: 10pt; FONT-FAMILY: Arial,Helvetica,sans-serif; COLOR: rgb(0,0,0)">
</div>
<div style="FONT-SIZE: 10pt; FONT-FAMILY: Arial,Helvetica,sans-serif; COLOR: rgb(0,0,0)">
I watered the pots and within a few weeks, had a lush growth of poppy seedlings in both pots. Both pots were side-by-side evenly watered and neither were fertilized. </div>

<div style="FONT-SIZE: 10pt; FONT-FAMILY: Arial,Helvetica,sans-serif; COLOR: rgb(0,0,0)">
However, within a month, every single poppy seedling in one pot died, and you can see a picture of both pots at http://www.ecoseeds.com/what-difference.jpg. </div>

These pot-tests of checking soil samples from the future revegetation sites have become the standard for Caltrans for their projects, ever since I taught them classes on the use of native plants 13 years ago, to discover and correct this problem.</div>

This is the second time I have encountered this very important issue in such a dramatic way that is often overlooked, when trying to get native plants established here in the West---so any guesses of what the difference was? </div>
