Re: Marketing Problems For Rain Gardens

**"* W* <c*@blazing-star.com>**

Hi All,
I am new to the GWL but could not help commenting on the rather acerbic 
assertions of Jeff on rain gardens, native gardening and "old" organic 
methods. Personally I have been a native gardener for over 20 years and 
never found any people who are native gardeners to be the plant police. 
Growing native plants is easy and relatively inexpensive if you grow your on 
from seed as one would grow any perennial. In fact many species in the 
perennial trade are originally natives turned into cultivars. Plants like to 
live with their friends and that is what a native gardener does is put 
natives with other like minded critters. The only "rule" is if one is doing 
a restoration only plant those species that were here prior to 1492 should 
be used from a local area.. The reason you probably had a problem with the 
the rain garden police is that they were probably landscape architects 
making work for themselves. You can use any plants that can tolerate 
periodic flooding, but natives have VERY deep root systems and it is only 
necessary to install them in a swale following natural contours.Dubuque Iowa 
has a rain garden program that doesn't require native plants but they 
function better if they have some mixed in. Go see two videos on rain 
gardens on a web site called greenscreenmc.org. By the way if you mix 
organic gardening with native gardening in a specific way you get  a new 
gardning style called Permacultue.

Hi Jeff et al,

This is a subject in which I am very interested and personally involved.
I understand that not all gardeners are environmentalists, but many of us
are; hence, the push for native plants. The entire topic is better
understood, if you also have a governmental perspective. New Jersey is a
home rule state, which means that local municipalities (not the county)
make all the laws to which local residents are subject. Superimposed on
those are county and state regs. Our state DEP passed very stringent
stormwater management rules within the past five years, that require that
all stormwater be disposed of on-site.

While we do have stormwater sewers, those that serve housing developments
empty into the dreaded detention (or retention, or infiltration) basin, a
visually hideous engineered method of holding large volumes of water
until it can safely disperse to groundwater, natural streams, ponds, etc.
These are generally grass monocultures or rip rap which, if not properly
maintained become weedy, overgrown maintenance nightmares. Suffice it to
say that anyone who can get away with not maintaining one will continue
to not maintain it. Right now, there are no detention basin "police,"
although I imagine this is ultimately the responsibility of our
overworked zoning officer.

One of my life's missions is to eradicate this type of detention basin
first, from my own town, then from the state of New Jersey, and then from
the face of the Earth, replacing them with stormwater gardens. A
stormwater garden is NOT a rain garden. The scale and purpose are vastly
different. I have found it very difficult to have conversations about
this with gardeners and non-gardeners alike, because people immediately
assume I'm talking about rain gardens. Rain gardens are more like an
alternative to a drywell, or a bog garden that operates on your roof
runoff (I have one), but they absolutely are not designed to handle the
runoff, for example, from a steeply sloping 5-acre lot.

This is no laughing matter. We have one instance of a Hatfields and
McCoys style feud over driveway runoff being directed onto a neighbor's
property, in which one of the residents attacked the other with a prybar
in the public road. Our town became involved because the runoff was also
causing flooding and erosion of the public (albeit dirt) road.

New Jersey DEP's preferred (Best Management Practice) for
detention/retention/infiltration basins is a vegetated stormwater garden,
also called a Marsh Meadow Garden. For anyone close to Morristown, NJ,
such a garden serves the vast parking lot of the the Frelinghuysen
Arboretum. For those who are not, Chapter 7 of the NJDEP Stormwater Best
Management Practices Manual can be downloaded from the NJDEP website:
www.state.nj.us/dep/

Jeff, the early entries into this field in our area, such as Pinelands
Nursery (a wholesale grower and supplier of native plants), became
experts at environmental restoration, as well as creating stormwater
gardens. Stormwater gardens that use native plants offer a more
attractive, low/no maintenance, and habitat-conserving alternative to the
monoculture detention basins that drive out native species of both plants
and animals. In our area, the first demonstration rain garden was on the
grounds of Rutgers University, which also sponsors the Ag Extension
Service's Master Gardener Program. Rutgers is also heavily into
environmental restoration/preservation programs, so that would add more
punch to the push for native plants.

BTW, my own experience with my soggy, boggy subsoil clay patch is that we
hand-excavated about 4-6 inches of "soil, " replaced it with 2" - 4"-inch
gravel that we had lying around for another project, put the same poor
soil back on top, and planted it up with free TB iris and Ligularia from
a friend. This spot is in hot, baking sun all day. The iris did fine. The
Ligularia's leaves were a little off-color the first year, but the plants
have since adapted and are thriving, despite the fact that we have done
nothing to improve the soil. In fact, the Ligularia are taking over.
