Green Roundtable
Consulting, education, training and strategic planning
to create healthy environments by integrating principles of
sustainability into mainstream planning, design and construction.
The Green Roundtable(copyright © Green Roundtable 2007)
Some key questions:
• Why are we using potable water for landscape
irrigation?
• Why are we getting sick in and around our own
homes? Are the places we live becoming more
dangerous than the places we work?
• Can landscape design choices play a role in
affecting climate change?
• Are we to believe that our „magic bullet‟ approaches
are always more effective than systems that nature
has had millions of years to work out?
• Are we complicit in some of the major flooding events
that have taken place recently?

The single best thing you can do:
LOSE THE LAWN!!!
The Green Roundtable(copyright © Green Roundtable 2007)
The trouble with turf
Lawn maintenance routines create multiple threats to
the environment through:
• Heavy fertilizer requirements
• Need to mow regularly and the resources that this
requires (gas, electricity, oil, etc)
• Pesticide and herbicide use
• Water use
They are energy and resource intensive. If possible,
LOSE THE LAWN!
The Green Roundtable(copyright © Green Roundtable 2007)
Alternatives to lawns
• Flower beds
• Wildflower gardens/ meadows
• Rock gardens
• Hedgerow
• Mulch beds
• Water features
• Artificial turf?
• Vegetable gardens
• Let it grow wild!
The Green Roundtable(copyright © Green Roundtable 2007)
Artificial turf?
The Green Roundtable(copyright © Green Roundtable 2007)
Permaculture
• Alternative to resource-intensive store-bought foods
• Emphasis on perennial plants like fruit trees and
shrubs and perennial herbs/ greens
• Incorporating edible plants into landscape
• See Permaculture Guild: http://northeasternpermaculture.wikispaces.com/Massachusetts
• http://www.hort.uconn.edu/Plants/ (plant database)
The Green Roundtable(copyright © Green Roundtable 2007)
Lawn care (if you must)
Follow good general turf management practices:
• Don‟t cut too short
• Use a drought-tolerant seed variety suitable for this
region
• Employ organic fertilizing and pest management
practices
• Aerate and de-thatch if necessary
• Water deeply only once a week (~ 1” of water); this
promotes deep root development
• Use rain sensors on irrigation systems!!!
The Green Roundtable(copyright © Green Roundtable 2007)
Lawn care (cont.)
• Avoid adding too much nitrogen as it can accelerate
growth and lead to thatch build-up
• Lots of clover may signal nitrogen deficiency
• Fertilize only if necessary! Get soil tested by local
agricultural extension service; see:
http://www.umass.edu/plsoils/soiltest/
• Chemical pesticides/ herbicides may kill earthworms,
contributing to thatch build-up
• Maintain good pH balance (typically w/ limestone)
The Green Roundtable(copyright © Green Roundtable 2007)
Lawn equipment
• 2nd best: electric mower
• Avoid use of leaf blowers
• Use a reel-type push mower
• Make sure lawnmower blades are sharp
• Keep equipment well maintained
The Green Roundtable(copyright © Green Roundtable 2007)
Low-impact turf management
• Leave clippings on lawn to return nutrients; mulch leaves
in place (but pay attention to nitrogen balance)
• Top-dress lawn with compost
• Fertilize with a home-brew fertilizer in a hose-end
sprayer (see next slide & Jerry Baker resources)
• Use a natural fertilizer if necessary; ex. alfalfa meal; use
suitable Nitrogen-Phosphorus-Potassium (N-P-K) balance
• Learn to live with a less-than-perfect lawn!
The Green Roundtable(copyright © Green Roundtable 2007)
•1 cup Epsom salts
•1 cup liquid dish soap
•1 cup Listerine mouthwash
•1 cup household ammonia (can
be lemon variety)
•1 can of beer
Lawn „tonic‟
This is a slight modification of a Jerry Baker
(The Impatient Gardener) recipe. Apply with
hose-end sprayer after mowing, dethatching
and seeding; treats around 2500 sq. ft.
The Green Roundtable(copyright © Green Roundtable 2007)
Low-impact turf management
• Hand-pull weeds
• Control tough weeds with spot application of a
„home-brew‟ solution
• Apply corn gluten meal (CGM) as a pre-emergent
weed control and fertilizer
• Tolerate a few weeds!
• Dense, healthy turf discourages weed growth
• See www.organiclandcare.net
The Green Roundtable(copyright © Green Roundtable 2007)
Corn-gluten meal
• Natural pre-emergent weed and crabgrass killer
• Generally applied in late April in northeast
• Provides slow-release nitrogen to lawn
• Apply when:
- Forsythias in bloom
- Soil temperature is ~60 deg. F.
• It really works and it‟s available locally!
The Green Roundtable(copyright © Green Roundtable 2007)
Green Practice:
Non-Toxic Weed & Pest Control
The Green Roundtable(copyright © Green Roundtable 2007)
The downside to chemicals
• May be toxic to humans
• Can adversely affect soil structure
• May kill desirable natural organisms
• Environmental justice issues
• Fossil fuel-intensive in their manufacture
• High persistence in environment
The Green Roundtable(copyright © Green Roundtable 2007)
Natural weed control strategies
• Mulches
• Natural chemical control
• Mechanical control:
- Hand pulling!
- Repeated cutting/ scraping of above-ground
parts may eventually kill root system
• Avoiding excessive tilling
• Destroy weed seeds by heating soil (w/ black plastic
sheeting)
The Green Roundtable(copyright © Green Roundtable 2007)
Typical mulching materials
• Bark/ wood chips (watch nitrogen balance)
• Plastic sheeting/ landscape fabric
• Stone/ marble chips
• Recycled rubber materials
• Newspaper
• Grass clippings and leaf litter (cut up if possible)
• Straw
The Green Roundtable(copyright © Green Roundtable 2007)
Natural insect control strategies
• Mulches
• Chemical control- use Integrated Pest Management
(IPM) strategies if you must use conventional pesticides
• Mechanical control:
- Hand picking!
- Blasting w/ jet of water from spray bottle
• Companion planting
• Biological control
• Sacrificial plantings
• Traps- Hanging pheromonal traps, sticky traps
The Green Roundtable(copyright © Green Roundtable 2007)
Natural „chemical‟ controls
• Insecticidal soap
• Dormant oils
• Diatomaceous earth
The Green Roundtable(copyright © Green Roundtable 2007)
Natural/ Biological pest control
Three major categories:
• Plant extracts
• Insect predators
• Pathogens
The Green Roundtable(copyright © Green Roundtable 2007)
Plant extracts
• Neem sprays
• Hot pepper sprays
• Natural pyrethrum spray
Neem tree
Chrysanthemums
The Green Roundtable(copyright © Green Roundtable 2007)
Insect controls
• Lady bugs; soil nematodes; trichogramma wasps;
common green lacewing
• Many are effective against a variety of insects-
aphids, thrips, mites, moths, beetles, whiteflies, etc.
The Green Roundtable(copyright © Green Roundtable 2007)
Natural pathogens
• Bacillus thuringiensis (Bt; trade names Dipel and
Thuricide)- Effective against gypsy moths, tent
caterpillar, tobacco hornworm, corn borer; variant
used in mosquito control
• Bacillus popilliae (Bp; milky spore)- Effective
against Japanese beetle grubs

Chemicals in landscape maint.
Reducing the risks
The Green Roundtable(copyright © Green Roundtable 2007)
General ways to address the risks
• First ask: Is this maintenance routine really
necessary? Can I live with the weeds/ pests, etc?
• Eliminate or avoid systems / features that require
significant use of resources to maintain (e.g. lawns,
swimming pools, expansive asphalt driveways)
• Assess the risks of using commercial products.
Learn what the chemical nasties are, know which are
in the products you use, and think twice about using
them
The Green Roundtable(copyright © Green Roundtable 2007)
Minimizing the risks
• Employ Integrated Pest Management (IPM) strategies
• Use safer alternatives found around the house (the
home „formulary‟)
• Use conventional chemical products as a last resort
• Use sparingly/ judiciously
The Green Roundtable(copyright © Green Roundtable 2007)
Minimizing the risks, cont.
• Store chemicals away from living spaces
• Understand risks associated with disposal, and
take adequate precautions
• Provide adequate ventilation/ use respiratory
protection where appropriate
• Mark treated areas/ Keep children & animals away
The Green Roundtable(copyright © Green Roundtable 2007)
The „Nasties‟
• 2,4-D
• Ammonia
• Arsenic
• Chlorine
• Hydrocarbons
• Ketones, including acetone
• Formaldehyde
• Benzene
• Methylene chloride
Some common chemical ingredients in home &
garden products:
The Green Roundtable(copyright © Green Roundtable 2007)
The Nasties, continued
• Phenol and cresol
• Pthalates
• PVC
• Trichloroethylene
• Toluene
• Perchloroethylene
• Nitrobenzene
• Naphthalene & paradichlorobenzene
• Mineral spirits; petroleum distillates
The Green Roundtable(copyright © Green Roundtable 2007)
Using „conventional‟ products
• Always read the label and follow directions
• If VOC‟s or other gases emitted, ventilate area well
• Dispose of properly
• Be mindful of “Caution” vs. “Warning” vs. “Danger”
• Try using in smaller quantities or more diluted
• Don‟t buy more than you need. Avoid mega-sized refill
bottles just because they seem to be a good value.
• Know what‟s in them; do the research
The Green Roundtable(copyright © Green Roundtable 2007)
• Check for ingredients on label
• Check “SIRI” database for Material Safety Data
Sheet (MSDS) at http://siri.uvm.edu/index.html
• Check for known dangers/ toxicity at NIH
Household Products Database
(http://householdproducts.nlm.nih.gov/index.htm)

Kitchen chemistry: typical ingredients
• Dish soap
• Rubbing alcohol
• Beer
• Cayenne pepper
• Ammonia
• Epsom salts
• Table sugar
• Aromatic oils, like clove oil
The Green Roundtable(copyright © Green Roundtable 2007)
Pesticides/ herbicides
Use 1 or 2 teaspoons of dishwashing liquid to a pint
of water in a spray bottle to kill many house and
garden plant pests, including aphids and scale; or use
commercial variety insecticidal soap like Safer‟s
The Green Roundtable(copyright © Green Roundtable 2007)
Spot herbicide for lawn
• 9 oz straight white vinegar
• 2 oz lemon juice
• 2 tbs table salt
• 1 tsp liquid dish soap
• Usually doesn‟t affect surrounding turf grass
• Combine in spray bottle
• May eradicate weeds with repeated application
• Only kills above-ground parts of dandelions, etc,
• Works best in full sun
The Green Roundtable(copyright © Green Roundtable 2007)
Insect repellant for garden
• 1 cup boiling hot water
• 2 tbs cayenne pepper
• 2 cloves minced or crushed garlic
• 1 tsp liquid dish soap
• Keeps several types of insects at bay.
• Pour hot water over pepper and garlic. Steep overnight
• Use in a spray bottle on vegetables & flowers; soak
all foliage; re-apply after rain
• Strain & add dish soap and another cup of water.

De-icers
• Always „cut‟ de-icers, especially rock salt, with
sand; a little rock salt goes a long way
• Favor mechanical „traction control‟; Use sand, kitty
litter or sawdust, or some combination of these
• Potassium Chloride (KCl), Magnesium
Chloride(MgCl), Calcium Chloride (CaCl) and Urea
can be more benign alternatives to rock salt- these
can sometimes provide needed nutrients to soil if they
end up on lawns, etc. (KCL & Urea can burn lawns;
some de-icers stain carpeting & flooring)
• Don‟t use indiscriminately; apply only where needed!
The Green Roundtable(copyright © Green Roundtable 2007)
De-icers, continued
• Along w/ providing traction, sand has ice-melting
properties as it absorbs heat from the sun
• Store de-icers indoors at room temperature to
increase effectiveness and minimize quantity needed
• Clear snow & ice barriers that prevent drainage of
paving & contribute to „refreeze‟ ice patches
• Try to sweep up sand/ salt after walkways/ driveways
are dry as it can clog storm drains; re-use it if practical

Stormwater management &
water conservation
in the landscape
The Green Roundtable(copyright © Green Roundtable 2007)
The Green Roundtable(copyright © Green Roundtable 2007)
Water conservation strategies
• Use grey water systems
• Employ xeriscaping principles
• Collect rainwater
The Green Roundtable(copyright © Green Roundtable 2007)
Xeriscaping (low-water-landscaping)
• Two major aspects:
-Making maximum use of available precipitation
-Selecting species with low water requirements
• Use mulches
• Create water retention landscape features
• Maintain high level of organic matter in soil
The Green Roundtable(copyright © Green Roundtable 2007)
Xeriscaping (low-water-landscaping)
• Use drip irrigation & soaker hoses; moisture sensors
• Group plants
• Use native plantings, they are better suited to natural
rainfall patterns
• Use plantings to create windbreaks & shade to protect
from drying winds and sun

Rainwater collection
• For 1000 sq ft roof area, 15 – 25,000 gallons of
rainwater can be collected annually in Eastern states
• Using rainwater helps to maintain aquifers and public
water supplies at adequate levels
• Combined with drip-irrigation systems, collected
rainwater can keep landscaping vibrant even during
drought conditions
• Rainwater does not contain chlorine so it is better for
plants, garden ponds, etc.
• Rainwater is free, and inexpensive to collect & store!
