Interesting article. But unless the sowing is done on an essentially
sterile surface, how does he differentiate between wanted plants and
weed seedlings? That's why, conventionally, sowing is done in
monoculture strips, for thinning later. It is easy to distinguish
between the wanted plants and the weeds.

in my established gardens there are only a few
kinds of weed seeds and not very many of those
if i keep them up.

it really isn't hard to distinguish a wanted
plant from the weeds, especially after you've
grown them to know what they look like as seedlings.

p.s. thanks for reminder, i need to thin the
beets...
