We abuse the land because we regard it as a commodity belonging to us. When we
see land as a community to which we belong, we may begin to use it with love and
respect.
Aldo Leopold, A Sand County Almanac
Â
by Bonnie Alter, London  on 11.25.09
DESIGN & ARCHITECTUREÂ
TreeHugger loves green walls--they are beautiful, environmental and good for
nature and the world. Suddenly they are popping out all over in London.
The American store Anthropologie just opened and they have installed a 3
storey high, 1500 sq. ft. living wall made of 14,000 plants and 15 varieties.
Designed byBioTecture, it is meant to represent a piece of plaid woven fabric.Â
It is an evergreen wall: no dead leaves needed whilst shopping. It includes many
houseplants such as the homely spider plant, ferns, lilies, euonymus and
heuchera. Pink leaves and tiny purple flowers give it texture and colour. It is
fed by rain water from the roof. As for the lighting, it must be partially
artificial. What a wonderful addition to a department store.
How do they do it? "Plants are grown vertically in our patented modular,
hydroponic-fed system. Each BioWall consists of a number of pre-grown modular
panels that can be erected with very little on-site time."
Then there's the outside wall. Growing on a corner of the Atheneum Hotel, a
not very imposing 70's building, this one was designed by Patrick Leblanc. He is
the famous creator of vertical walls who did the one outside the Quai Branly
Museum in Paris.
It's such a hit that this wall has its own Facebook entry. It is 8 storeys high
and has native plants and flowers as well as an assortment
of Urticaccae--nettles--grown in Japan and India and planted here because the
humid microclimate is the perfect spot for them.
How does he do it? "A system of slats is used to secure artificial felt and
myriads of strategically placed plant roots, with automated watering and
fertilisation. It's nothing short of botanical architecture. "

In the southeast, we've had drought problems for the past few years. The new
permeable parking lots are catching on. They don't generate the heat of a
conventional parking lot or driveway and allow rain to penetrate the ground
instead of running off. The local property tax structure includes a significant
increase for what they call run-off tax. You are taxed at a higher rate for
every square foot of non-permeable surfaces on your property such as roof area,
driveways, patios, etc. You know other county governments will jump on that
bandwagon to raise their tax revenues so you will pay dearly for all surfaces on
your property that create run-off. The permeable surfaces are an idea whose time
has come!

There are 2 types of green driveways that I'm aware of. Both employ pervious
pavers, one where the gaps are filled with soil and grass is grown in the gaps.
The idea of this system is to reduce compaction and to allow for limited water
infiltration. I have seen these used in high quality natural areas as a way to
allow heavy equipment and vehicles to move freely into a area with minimal
damage to the adjacent ecosystem.
The other application for pervious pavers are where the gaps are filled with
finely crushed stone with a underlayment of the same. The idea here again is to
allow a greater amount of water to infiltrate to a sub soil level and often to
be directed into a Bioswale system which usually feeds into a Rain Garden
complex. The following link can explain more.

Hi there. Just wondering if anyone has a "green driveway" or has thoughts on
this idea. Was wondering whether this costs more or less than a conventional
driveway and how well it lasts over time. I have a very old and beat up asphalt
driveway that I was thinking of pulling up.
Thanks very much!

Funny ive just finished laying a grass drive. ive laid two this year now and
regularly maintain the first. its lasted really well (been down since feb), cuts
pretty easy just like regular lawn. Bit pricey but worth the money. just for the
blocks its roughly ₤40.00 a square meter. Shop around to buy though! Have a
look on www.wickes.co.uk product code is 187-886 permeable grass grid.
Sorry forgot to answer one of your questions. it works out about 20% cheaper
than a top quality drive, and about 10% more expensive than a cheap drive. Check
with local authority first though.
good luck

If you google it, a ton will come up, but here is a link to a short New York
Times article about it:
http://www.nytimes.com/2006/05/04/garden/04room.html
The general idea is to create something that is porous, instead of a concrete or
asphalt slab that just sends more water into your town's sewar system. An old
style one would be just having two strips of cement as your driveway (for your
wheels) with grass growing in the middle. There are numerous other ways to do
it today. Like with concrete blocks with holes designed for grass/plants to
grow within it. I am just learning about this...
Thanks to Michael for the tip on checking with your town - it could present a
zoning issue.
Thanks everyone, patti

New rating systems seeks to promote sustainable landscapes from shopping malls
to city parks
Jeremy Hance
mongabay.com
November 15, 2009
The Sustainable Sites Initiative has developed the United States' first rating
system for the design, construction, and on-going maintenance of a wide-variety
of landscapes, both with and without buildings, including shopping malls,
subdivisions, university campuses, corporate buildings, transportation centers,
parks and other recreation areas, and single-family homes.
"While carbon-neutral performance remains the holy grail for green buildings,
sustainable landscapes move beyond a do-no-harm approach," said Nancy
Somerville, Executive Vice President and CEO of American Society of Landscape
Architects (ASLA). "Landscapes sequester carbon, clean the air and water,
increase energy efficiency, restore habitats and ultimately give back through
significant economic, social and environmental benefits never fully measured
until now."

The ratings system analyzes sites' energy and water usage, waste management,
impact on land, and use of natural resources both during construction and
maintenance.
"We are facing unprecedented environmental challenges such as water scarcity and
climate change that require fundamental changes in the way that we interact with
the land," said Susan Rieff, Executive Director of the Lady Bird Johnson
Wildflower Center at The University of Texas at Austin. "This voluntary rating
system and guidelines covers all aspects of working with outdoor spaces of all
sizes, and provides information for designing landscapes that go beyond beauty
to actually improving ecosystem health and the health of communities for
generations to come."
Dozens of experts across the US spent four years developing the Sustainable
Sites Initiative's rating system, which has been a partnership with ASLA, the
Lady Bird Johnson Wildflower Center, and the US Botanic Garden. Built on a
250-point scale, the ratings system grants between one to four stars based on
whether the site has achieved 40, 50, 60, or 80 percent on the scale
respectively.
"Landscapes can give back," said Holly H. Shimizu, Executive Director of the
United States Botanic Garden. "We believe that as these guidelines become widely
used, not only will they be as transformative to the landscape industry as LEED
was to buildings, but more than that, they will allow built landscapes to be
regenerative like natural landscapes, and assist in mitigating some of the most
pressing environmental issues we face today. We need to acknowledge our
landscapes' value, treasure them and cultivate them sustainably and responsibly.
The need is urgent, the time is now and these guidelines, when used correctly,
are the tools."
In order to test the system, the Sustainable Sites Initiative has called for
pilot projects on any type of designed landscape of at least 2,000 square feet.
Reports issued by the Sustainable Sites Initiative, entitled The Case for
Sustainable Landscapes and Guidelines and Performance Benchmarks 2009, are
available for download at www.sustainablesite s.org.

I think the only kind of "green driveway" is a dirt strip. ;)

Excellent question. My drive and house are over 60yo and the drive really needs
work.
Better check with your City before you do anything.

Hi there. Just wondering if anyone has a "green driveway" or has thoughts on
this idea. Was wondering whether this costs more or less than a conventional

Thanks very much!
Hi everyone. Anyone have any good advice on where/how to buy inexpensive gravel
for landscaping purposes? I live on long island (Nassau), in case anyone can
recommend a place. And I am not looking for huge amounts, my property is small.
Thanks for any leads!
"Zen" is a Japanese school/sect of Buddhism The word "zen" means meditation. A
zen garden is meant to be used as a meditation garden.
In the west most people think of very simple gardens of sand or gravel with a
few large stones. The extreme maintenance of these gardens is used as a form of
meditation.
Go with your "heart" and do what feels right for you.
I am in the process of making one for my self based on a Buddhist altar. A low
mound with a very large statue of the Buddha ( luckily this was a gift, about
one third life size, rather expensive) with cannas as a back drop and a rose to
one side. I am adding mondo grass to surround the entire area and intend to add
a "wild" Eastern Red bud this winter as soon as I can transplant it. I have a
few large "river rocks" in front with an asian flower pot for an insense
burner. A young red oak about 10 feet away in the back of this.
The "garden" meant to be viewed from my deck with a flagstone stone path in
front and is about 10 feet long by 8 feet deep.
Just keep it simple.

One way to slow this down in the home landscape is by using slow release
fertilizers, like Milorganite. Or returning nitrogen-rich grass clippings to
your lawn. I'm not sure what can be done with large-scale agriculture.

The rest goes missing, washing into ecosystems. This is partly because the
fertilizer is wastefully applied, and partly because the new green-revolution

The Nitrogen Fix: Breaking a Costly Addiction
Over the last century, the intensive use of chemical fertilizers has
saturated the Earth's soils, waters, and atmosphere with nitrogen. Now
scientists are warning that we must move quickly to revolutionize agricultural
systems and greatly reduce the amount of nitrogen we put into the planet's
ecosystems.

A single patent a century ago changed the world, and now, in the 21st century,
Homo sapiens and the world we dominate have an addiction. Call it the nitrogen
fix. It is like a drug mainlined into the planet's ecosystems, suffusing every
cell, every pore - including our own bodies.
In 1908, the German chemist Fritz Haber discovered how to make ammonia by

coursing through the planet's ecosystems are growing fast. We have learned to
fear carbon and the changes it can cause to our climate. But one day soon we may
learn to fear the nitrogen fix even more.
A major international survey published in September in Nature listed the
nitrogen cycle as one of the three "planetary boundaries" that human

On top of all of the problems created by fertilizer, 5 percent of the world's
natural gas production is being used to make it. We are running out of the easy
gas, and getting it out of shale in the midwest has huge environmental impacts.
When we run out of gas we are back to guano.

How would nitrogen dependence be reduced if we stopped eating meat? Certainly
plants that feed livestock are fertilized. I lack the data to run the numbers on
that, but someone at Yale just might be able to.

Great piece, Fred. Just wanted to add that denitrification doesn't just produce

Dear Friends,
Just a few more days and a few more spots in the first Permaculture
Design Course happening in the U.S. Virgin Islands at the Virgin
Islands Sustainable Farm Institute, followed by Gaia University Degree
programs in December.
Info below.
-Living Mandala
____________________
Permaculture Design Certificate Course
Virgin Islands Sustainable Farm Institute
November 9-22, 2009
U.S. Virgin Islands
For More Info & Registration Visit LivingMandala.com
In Association with
Virgin Islands Sustainable Farm Institute & Appleseed Permaculture
Facilitators & Instructors
Ethan Roland, Dyami Regan-Nelson, Ben Jones
Course Description
Learn how to create sustainable, productive, and beautiful human
environments using natural ecosystems as models. Permaculture is an
evolving and expanding design system for ecological living,
integrating plants, animals, buildings, people, and communities.
Through experiential, participatory, field-based, and classroom
learning, participants will explore the relationships between
personal, social, and ecological sustainability in the rich context of
life at the Creque Dam Farm, home of the Virgin Islands Sustainable
Farm Institute in St. Croix, USVI.
Course Components
This two week program focuses on design as an ecological process,
assessing natural systems, and weaving integrated solutions to local
and global problems. Faculty guide students through the design of
projects beginning with interviews of clients, needs assessment,
development of real solutions, and culminate in a formal permaculture
design and presentation.. The design course culminates with
presentation of design work to the class, community, and clients.
Topics Include
Site analysis of vegetation and wildlife, natural building, compost
and soil, water preservation, guilds, zoning, forest gardens, seed
saving, grey water, and tools for planning, mapping, and executing a
sustainable, abundant ecosystem and human culture
Cultural Mentoring
Woven throughout the weeks will be the principles of Cultural
Mentoring. Cultural Mentoring is derived from native teachings from

achieving long term sustainability within a healthy environment. These

Sustainability, Community, and Environment. We use these focal points
to guide decisions that will promote our farm’s vision. For more

Fescue doesn't create a sod, its a bunch type grass and doesn't produce rhizomes
( underground stems ) so I'm going to assume that you're trying to get a
established turf in the shade as fescues are usually used in shady situations.
Depending on your location and climate, a rule of thumb is to go deeper for dry
climates or a minimum of 4 inches of top soil. 2 inches is sufficient for moist
climates.

Hello
How much soil depth do you have to have for new sod 90/10 fescue/kbg in
order for the sod to survive?
Thanks

I usually till the exsiting soil first, roll with a small sod roller (you can
usually find at a rental store) and add about 1" of organic compost. Then lay
the sod and roll again.

Many weed seeds will and can survive in soil for several years so you did more
harm than good when you stripped out soil and turned it over, by doing that you
only brought more seed to the surface where they were able to get the light in
order to germinate. You don't specific if your flowers are annuals or perennials
so if they're annuals than the other posters idea with cardboard and compost
will indeed reduce the amount of seed germination in the future. If your flowers
are perennials than your best bet is to plant more of them to crowd out the
weeds, try some Florida natives as they will thrive with almost no care and are
great colonizers.

Hi there -
I'm new to the group - live in Central Florida (zone 9) and am finally at my
wits end with weeds. All of my flower beds are just overrun by weeds. I have
tried removing the top layer of soil, turning the soil over, putting down a
thick layer of mulch, etc. and nothing seems to work. Short of putting down some
sort of nasty chemicals (would rather not with young children and pets in the
yard) what can I do to get ahead of these weeds? Hoping to get it under control
during the winter months ... before the growing season starts up again!
I just posted on MasterGardening on Facebook also - hoping to get some good tips
there too. Are you aware of any other gardening groups on Facebook? I seem to be
better at keeping up with those than my Yahoo Groups!
Any help you can offer would be greatly appreciated!

Sheet Mulching with Cardboard
Use compost or manure below, then add a THICK layer of cardboard
(overlapping every edge 6"), then a nice thick layer of mulch. This should
reduce weeds and weed seeds significantly but do NOT be shy with the
cardboard.
You can google this also.

Keep knocking, and the joy inside will eventually open a window and look to
see who's there.
