Smart Garden: How to install your own French drain

Here's one way to prevent runoff water on your roof from causing damage to the side of your house. Jan. 25, 2016

Its hard to believe, but the winter rains will arrive in the inland California landscapes sometime in the next few months, and we gardeners will rejoice! Butare we ready?

September is a good time to prepare for fall gardening and, hopefully, for winters wet season.A general landscape tidying up is in order, including making sure our garden areas are not going to add pollution problems to our local downstream waterways, drainage ditches, or even groundwater aquifer.

In Californias Central Valley, there is a new concern showing up on our waterways, most likely coming from home gardens, vector control sprays around our homes and workplaces, as well as from indoor household waste water, because pesticides often pass through water and waste water treatment, and are not removed.

Fifteen Central Valley surface water bodies have listed pyrethroids in the waterway, making the streams impaired.The California State Water Resources Control Board has tasked Central Valley cities, through their stormwater permits, to reach out to consumers and educate them about these toxins, specifically the six active ingredients found in household and garden products, namely bifenthrin, cyfuthrin, cypermethrin, permethrin (vector control), esfenvalerateand lambdacyhalothrin.You may notice in the next year or so, educational flyers like Our Water-Our World,appearing in the garden centers where you shop, courtesy of your local municipalities.

Pyrethrins, on the other hand, are a class of organic compounds normally derived from Chrysanthemum that have potent insecticidal activity by targeting the nervous systems of insects, but have less lasting damage to the downstream waterways ecosystems.

Butdont wait until you are in the garden product aisleto do your homework about pyrethroids versus pyrethrins.By spending timeahead of shopping, by carefully studying your pest problem, you may better understand how to solve the problem without causing harm to your local creeks or beneficial insects.

According to Paul Bedore, a stormwater consultant who is helping cities understand the implication of the new pyrethroids mandate,a few aquatic crustaceans and insects in local waterways, particularly the crustacean Hyalella azteca, can be sensitive to pyrethroids. Pyrethroids affect the nervous system of these organisms, as they would insects around a home or garden, which can cause them to become temporarily paralyzed or even to die.As a result, state regulators are concerned about pyrethroids adversely affecting aquatic ecosystems.

These pesticides still are found for sale and are often found listed as the active ingredient, or AI, found in many products used for killing lice, dog shampoo flea and lice baths, wasp killer spray, bed bug killer, ant killer, as well as in garden pest products. Vector control companies also use pyrethroids in their arsenal against common home pests sprayed outside along the perimeters of our homes.When loose sediments, laced with pesticides, move during rainstorms, waterways are polluted.

As a gardener, integrated pest management, or IPM strategies are often more desirable solutions.IPM requires a longer view of your garden as an ecosystem, which works towardprevention of problems, through techniques the University of California promotes on its IPM website: such as biological control, habit manipulation, modification of cultural practices, and use of resistant varieties. Pesticides are used only after monitoring indicates they are needed according to established guidelines, and treatments are made with the goal of removing only the target organism. Pest control materials are selected and applied in a manner that minimizes risks to human health, beneficial and nontarget organisms, and the environment. http://ipm.ucanr.edu/

Good gardeners consider the whole health picture of their landscape; as habitat for beneficial insects, as well as a source of food, enjoyment and beauty for their family and community.A new consideration is the effect that his gardening is having on local waterways.Simple reading of labels, understanding active ingredients, and studying the pest problem and using IPM can prevent water pollution from happening.

Heres what you can do to limit your local watersheds pollution from your garden.

Happy Gardening!
