grass of other weed that can compete with this seed and win. And you
must expect one rain period that can maintain wet the superficies of
the land for more of tree days .

Thanks for the information. It led me to arrowhead clover or Berseem
which led me to this website:

According to them, white clover is better suited for the colder
climate here
in South Dakota and also white clover reseeds very high.

Tell me Javier, since I have never collected the seeds of clover. Does
clover have
one seed crop per year? When does the seed mature? How will I know the
seed
is mature? And when can I collect and gather the seed?

This clover seed collecting is a new experience for me.
Thanks in advance for any answers.
