Why
Change Your Little Piece of Heaven on Earth?
Honeoye Lake is one of those
rare places in the world where woods, lake, hills and sky form a particular
vision of Eden: beauty and tranquility abound.
As with the original Eden, however, there may be a bit of trouble lurking
in the background.
The water’s edge that lures children to the swimming raft and Granddad to the fishing rod is too often altered by well-intentioned projects meant to “improve” the property. Trees and shrubs are cleared away to open that priceless view of the lake. Lawns are established, fertilized, watered, mowed and fertilized again and again.
When the rains come, soil that is no longer anchored by tree and shrub roots washes into the lake. Nutrients washed from the lawn or attached to soil particles feed aquatic plants in the lake. plants, (both macrophytes and algae) grow lushly, reproduce and die. Aerobic bacteria feed on the dead plants, depleting the water of oxygen. Fish and aquatic insects suffer oxygen deprivation. The lake water “smells funny,” and swimming and fishing become less attractive.
Geese are attracted to mowed lawns where they can see predators coming at a distance. Even without the neighbor who feeds waterfowl when she thinks no one is looking, a closely mowed lawn is goose bait. A flock of geese produces goose poop – lots of it. This is also fertilizer that will wash into the lake, as are the droppings of the family dog that tries to chase the geese away.
For many different reasons – from lawn fertilizers and goose poop to faulty septic systems – the lake suffers from the impacts of the good intentions but less than ideal choices of the people who surround it.
The municipalities and residents of Honeoye Lake watershed have committed themselves to improving the water quality of the lake. The alum application during the past year represents a valiant effort to sequester excess phosphorus already in the lake, preventing it from recycling into more and more plant growth. The community’s commitment to preventing more phosphorus from entering the lake is equally important.
Phosphorus is the nutrient
in least supply in Honeoye Lake and all of the other Finger Lakes.
Adding any amount of phosphorus supports immediate plant growth. 1 lb
of phosphorus spurs the growth of 500 pounds of plant material in the lake.
Keeping phosphorus out of the lake is vital to continued water
quality improvement.
Why Use Low or No Phosphorus Lawn Fertilizers?
Lawn fertilizer carried in runoff is a source of phosphorus in Honeoye Lake. Fertilizer that grass can’t use washes away in runoff or enters the groundwater – which is also moving toward the lake
Most established lawns do not need additional phosphorus. Cornell University surveys indicate that most established lawns don’t need fertilizer. Only one of every ten lawns examined needed any fertilization at all. What most lawns needed in order to stay lush and healthy was less care!
Mow grass high – about 3 – 3 1/2 inches. This enables grass to root deeply and grow thicker, crowding out weeds and keeping the roots cooler which reduces the need for irrigation. Leaving grass clippings on the lawn instead of bagging them up recycles nitrogen into the root mass. This does not cause thatch.
Thatch is a
layer of decomposing plant tissue made up mostly of stems and roots, not grass
clippings. A thin (up to ˝ in.) layer
of thatch above the soil is beneficial. A
thick layer leads to increased disease and insect problems, drought stress and
winter injury. Thick thatch usually occurs on lawns that have been
heavily fertilized and watered for constant lush growth. Compacted, poorly
drained and acidic soil contributes to thatch problems. The use of pesticides
can reduce or eliminate microorganisms that break down thatch. Mechanical
removal works temporarily. Core aeration is effective in managing thatch.
Low or no phosphorus fertilizers
are a good solution to a the goal of maintaining a healthy lawn beside a healthy
lake Keeping a lawn in a state of forced, constant, lush growth by excess
fertilization and watering leaves it more vulnerable to pests and weather
damage.
Local businesses that stock
low and no phosphorus fertilizer include: The Greenery/Ward’s Landscaping in
Honeoye, Country Corners Nursery in Bloomfield, CountryMax in Victor and
Lowe’s in Canandaigua. Other
nurseries and businesses may also have such fertilizers available. Read the label carefully.
Another means of
preserving an attractive property while safeguarding water quality in the lake
is to plant native species of trees, shrubs and groundcovers instead of
investing much more time, energy and chemicals into growing exotic ornamentals.
Why Plant
Native Species?
The natural landscaping movement
is the newest – and oldest - word in home landscaping.
All across North America, more and more people are landscaping their
homes, schools, businesses and churches with native species.
Why all the interest?
Native species are plants that
grow naturally in particular areas; they were established originally without
human introduction or intervention. These
plants have several appealing factors.
Native plants are
low-maintenance. As they have adapted to local climate and soils over
millennia, native plants are vigorous and hardy, surviving winter cold and
summer heat. They are usually
resistant to local pests and diseases. Once established, they require no
fertilization or irrigation. Reducing
fertilizer runoff to the lake reduces aquatic plant growth.
Native plants stay put. Natives
rarely become invasive (spread rapidly). Other plants, animals and
micro-organisms in a native plant community keep populations in check.
Introduced species lack these natural checks and balances.
Native plants give back to
their community. Birds, butterflies, amphibians and other desirable wildlife
receive food and shelter from native plants. Introduced ornamentals do not have similar habitat value
Native plants have deep roots. Root systems hold soil in place and
help water infiltrate, reducing soil erosion and runoff.
Roots of mature trees reach down to the upper levels of the water table.
Smaller trees such as dogwood form a dense web of roots that extend
downward for several feet. Turf
grass roots commonly reach down about 3 inches and offer far less erosion
protection.
Native plants are interesting.
Native plants reveal a diversity of form, foliage, flowers, textures, heights
and shapes. Many have interesting
bark or seedpods that are visible in the winter.
Many were used in Native American culture for food, medicines or dyes.
Others were used by European settlers similar domestic purposes.
Native plants can provide a growing link to the past.
Native plants give you more
of what you came here for. Leave the landscaping to Mother Nature rather
than spending time, effort and money to turn your Honeoye Lake home into an
urban landscape. Why clear out the
natural plants to install others that need pampering, mowing, watering, weeding,
spraying, pruning, staking and defending from the native wildlife?
Relax. Restore your shore to
what the “original designer” intended.
Leave that mower in the storage shed, unfold that lawn chair and listen
to the birds sing in the (native) trees.
