Gardening Action

Spring is time for ACTION!



Starting early will help you stay ahead of pest and disease problems.

Wouldn't it be great if you could avoid all the pest and disease problems this summer that you have struggled with in the past? To be able to skip the sprays and dusts and the potentially hazardous exposure to your family and pets? Well you can reduce if not eliminate these problems, and now's the time—when you're prepping and planting—to make it happen.
====================================================
Start Healthy

Healthy plants resist infestation, but a sickly, stressed plant will be an open invitation to pests and disease. As a gardener, your job is to provide ideal growing conditions, so the plants in your garden grow strong.
Organic gardeners know that the time to add soil enhancing organic amendments is in the Fall. This allows ol' man winter the opportunity to break down and release the essential ingredients needed for a healthy soil. If you weren't able to get your amendments added in the fall, consider trying to get a good early cover crop in. Or find a good quality compost with an organic fertilizer for your spring amendment.Take the time to loosen the soil with a garden fork down to about 12 inches deep. Doing this will open up channels for air and moisture, and make it much easier for roots to penetrate the soil. ========================================================
Healthy Starts


Begin with your own healthy seedlings or buy strong starts. Don't skimp on this early expenditure. Buying plants that are on sale because they have been on the shelf too long, or are leggy and leafless saves you nothing and costs you in the long term. The plants will take your valuable time and resources and then under-produce, or worse yet not produce at all.


========================================================
Provide Protection

Whether you grow your own starts or buy transplants for your garden they will need protection from the elements. A period of hardening off, where the plant is set outside in a sheltered area for a few hours everyday, followed by cover from the harsher outdoor conditions once it is transplanted, will be needed. The young plant will need a few days to get its' roots established and will require steadfast protection. Stressing the plant at this stage will weaken it and leave the door open for pests and disease.


======================================================
Devine Diversity


By planting a wide variety of plants in your garden you discourage any onslaught of any one particular pest. Many plants attract beneficial insects and predators of pest such as birds. By adding a small patch of marigolds here and there with a sprinkling of alyssum, dill or fennel you will be attracting beneficials as well as giving yourself a treat. Many of the plants that are considered weeds in many gardens are actually much needed food sources for attracting the main warriors in your fight against pests. Keeping a small patch of naturally occurring native plants will help maintain a healthy balance in your garden.

Some Beneficial Insects That Help Control Noxious Pests

Ladybugs

Every gardener has heard of the darling little ladybug, which is renown as a voracious eater of many garden pests. Ladybugs and their larvae feed upon aphids, mealybugs, spider mites, scales, whiteflies, and many other smaller insects. They prefer aphids as their primary delicacy, but also eat the eggs of other insects, which is a real boon to gardeners. After an adult female's eggs hatch, their larvae alone will readily consume literally hundreds of aphids.

Green Lacewings

Lacewings serve as beneficial predators either as eggs, larvae, or adults. Their larvae will eat large numbers and many varieties of aphids, and also devour mealybugs, whiteflies, thrips, leafhoppers, red spidermites, and a variety of other soft-bodied noxious insects.

Dragonflies and Damselflies

These two beneficial insects are also a great aid to gardeners, as they catch and eat flies, termites, beetles, mosquitoes, and other noxious flying pests. Research indicates that dragonflies can zoom through the air at about 60 miles per hour while catching and eating their lunch along the way! Damselflies are not as large as dragonflies, neither can they fly as fast. However, they are also superb beneficial insects to have in your garden, as they also feed on many garden pests.

Predator Mites

There are several species of mites that feed on spider mites and sometimes will feed on thrips. These predator mites will not damage your plants as do the spider mites.

Scale Parasites

A very small parasitic wasp (Aphytis melinus) is another beneficial insect that will help keep your garden healthy. This little wasp attacks and destroys red scale as well as other types of scale on plants. As with any type of wasp, bee, or yellow jacket, please exercise care to avoid getting stung!

There are many other beneficial insects that can be introduced to your garden to help control common garden pests. These mentioned here are only a few of the most bothersome to gardeners, and will give you a starting point. If you need help identifying or controlling any of your garden insects, either beneficial or nonbeneficial, there are many excellent resources available. One very outstanding organization known as CSREES, Cooperative State Research, Education, and Extension Service, is a dynamic new international research and education network. The services of CSREES expands the research and higher educational functions of the former Cooperative State Research Service. This agency offers a wealth of information to not only gardeners but also the entire agricultural community.

A few tips to attract beneficial insects to your backyard

The needs of beneficial insects are not difficult to meet if you have a real desire to lure them to your garden. Many, if not all, probably already exist in your garden. Here is a short checklist that outlines their needs.

Food

Beneficial insects will be happy with early blooming plants that contain nectar and pollen they can feed on. Some early bloomers they are attracted to include pansies, alyssum, Queen Anne's Lace, and fennel. Later in the season there are many others such as coneflowers, cosmos, goldenrods, or lavender that they will enjoy.

Water
Water is essential for all insects and is easy to provide. Any type of container that will hold water can be placed in an inconspicuous place in your garden. It can be kept filled with water as you sprinkle your flowers, or you can also just let rain and dew collect in it. Just be sure there is always some water in it.

Shelter and a place to rear young

Try leaving some leaves or other debris under some of your larger shrubs as a place of shelter for beneficial insects. Or, place a dead log or some rocks and brush in one corner of your garden to provide a place of protection for them during cold or inclement weather. Like your butterflies, beneficial insects are cold-blooded and don't like cold, windy weather. They like a nice cozy place to hide until the sun comes out again. These sheltered places will also serve as a great place for them to raise their youngsters!

Avoid pesticides!

Select only organic or other natural insect control substances in addition to your beneficial insects if your garden should develop a serious infestation of harmful pests. If you really MUST resort to pesticides, try to select those that are the least toxic and use them sparingly. Otherwise, you will surely risk killing your beneficial insects — AND your butterflies and hummers as well!

Offshore Wind Farm Could Blow Away Energy Needs

Offshore Wind Farm Could Blow Away Energy Needs: "Wind power could supply all the energy needs of much of the East Coast and then some, if a phalanx of wind turbines running from Massachusetts to North Carolina were installed offshore, a new study concludes."

Seeing Red: Palm Oil Biodiesel



In the enthusiasm for renewable energy and taking care of our environment, it is easy to assume that making fuel from plants (biofuel) must be by definition "green" and renewable. However when it comes to energy issues, easy assumptions can be dangerous assumptions. In previous years some politicians and advocates in Europe have made these assumptions without sufficient thought and research and secured government subsidies for companies importing palm oil from South East Asia to make biodiesel for transport and for use in electricity generation.

The demand for palm oil in Europe has soared in the last two decades, first for use in food and cosmetics, and more recently for fuel. This cheap oil can be used for a variety of purposes, including as an ingredient about 10 percent of supermarket products, from chocolate to toothpaste.

Promoted by hundreds of millions of dollars in national subsidies, the Netherlands quickly became the leading importer of palm oil in Europe, taking in 1.7 million tons in 2006, nearly double the previous year.



Now it is increasingly difficult to ignore the mounting body of scientific evidence that palm oil plantations in Indonesia and Malaysia, rather than preserving the environment are in fact actively destroying it. By subsidising biofuels, European governments have artificially raised demand for palm oil in Europe, and accelerated the destruction of huge areas of rainforest in South East Asia. Palm oil plantations are often expanded by draining and burning peatland, releasing enormous amounts of carbon dioxide into the atmosphere. As a result Indonesia has become the world's third largest emitter of carbon dioxide, ranked after the United States and China, according to a study released in December by researchers from Wetlands International and Delft Hydraulics, both based in the Netherlands.

The 2003 European Union Biofuels Directive, which required all member states aim to have 5.75 percent of transportation run on biofuel in 2010, is now under review. In the Netherlands, the data from Indonesia has prompted the government to suspend palm oil subsidies.

In Europe a small amount of rapeseed and sunflower oil is used to make diesel fuel, however increasingly plant oils are being imported from the tropics, since there is simply not enough plant matter or land for biofuel production at home. So while the billions of dollars in European subsidies appear to have reduced carbon emissions in European countries by importing biofuels, this has been achieved by exporting them and increasing their impact many times by the permanent destruction of rainforest and peatland in South East Asia.

For anyone familiar with how the ethanol industry works in the United States, they will be unsurprised to learn that the palm oil industry was promoted long before there was adequate research. Biofuel Watch, an environment group in Britain, now says that "biofuels should not automatically be classed as renewable energy." It supports a stop on subsidies until more research can determine if various biofuels in different regions are produced in a nonpolluting manner. The group also suggests that all emissions arising from the production of a biofuel be counted as emissions in the country where the fuel is actually used, providing a clearer accounting of environmental costs.


BEFORE: rainforest on the Indonesian part of the island of Borneo

Friends of the Earth estimates that 87 percent of the deforestation in Malaysia from 1985 to 2000 was caused by new palm oil plantations. In Indonesia, the amount of land devoted to palm oil has increased 118 percent in the last eight years.


AFTER: a palm oil plantation

Peat is an organic sponge composed of 90 percent water that stores huge amounts of carbon, which when it is drained emits huges amounts of carbon into the atmosphere.

Even worse peatland is often burned to clear ground for plantations. The Dutch study estimated that the draining of peatland in Indonesia releases 660 million tons of carbon a year into the atmosphere and that fires contributed 1.5 billion tons annually.

the haze has covered much of SE Asia for extended periods of time since 1997

The total is equivalent to 8 percent of all global emissions caused annually by burning fossil fuels, the researchers said. "These emissions generated by peat drainage in Indonesia were not counted before," according to a Wetlands spokesperson. "It was a totally ignored problem."

While for the moment the widescale destruction of rainforests in South East Asia continues, hopefully the palm oil story will serve as a cautionary tale which will lead to much better informed policymaking and behaviour. Politicians must resist the urge to rush to legislate and subsidise in order to bask in the glow of being seen to be "doing something" while a number of so-called green companies profit from taxpayer subsidised destruction. Energy policy must make sense from a scientific (i.e. it should be energy positive), economic and environmental viewpoint. However the continued promotion of ethanol and coal-to-liquids calls for continued skepticism.

Landmark UN Report Confirms Global Warming Science

The IPCC and scientists from 113 countries issued a landmark report in Paris on Friday saying there is a 90% chance global warming is caused by human activity, and predicting that hotter temperatures and a rising sea level will continue for centuries regardless of what measures are taken to reduce greenhouse gas emissions.

The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) in 1988.

Turning Black Coal Green

Turning Black Coal Green: "Big lumps of sooty coal hardly seem like the future of energy, but that’s exactly what the U.S. Department of Energy predicts. Consumption of the fossil fuel—the main source of greenhouse gas and a major contributor to acid rain, smog and mercury poisoning—will hit 10.6 billion tons a year by 2030, a near doubling of the 5.4 billion tons burned in 2003, according to the
