hello, after some years of intense observation I must agree that
(in our European regions) Solidago Canadensis really is a pest, it
not only expels native species but also spoils soil, so other
flowers will not grow in eventual gaps
so could anyone from Northern America describe with a few words
the concurrency of this plant with others, i. e. succession,
cultivation methods, distribution and so on
many thanks in advance

I live in New Mexico, where Solidago canadensis occurs, but isn't
common or invasive. It grows along ditchbanks and some waterways. It
is a Tallgrass Prarie plant, and generally grows with grasses and
other plants that generally get over 1 meter tall. I would not be
surprised if it was susceptible to a species of root mealybug that
periodically decimates stands of the somewhat related Gutierrezia
sarothrae.
