The word lawn comes from the Old English for an “open space." Both European and American aristocracy had estates with lawns, but working class people used their land to grow food. 

A big change came for the American “lawnscape” in the 1950s in response to the trauma of WWII. In new, orderly housing developments such as Levittown, the first neighborhood lawn standards were adopted. Military uniformity prevailed with ready access to cheap, war-surplus chemicals that had been rebranded as lawn fertilizers and pesticides. Now a $60 billion per year industry, lawn grass is the cheapest landscape to plant and the most expensive to maintain.        

In order to thrive, American lawns consume 20 trillion gallons of water, 90 million pounds of fertilizer, 78 million pounds of pesticides and 600 million gallons of fossil fuels per year. We now know so much more about how dangerous and unnecessary these chemicals are, and how many resources are drained maintaining on our yards. 

The next generation of lawns will be less toxic and more environmentally friendly: smaller (think area rug instead of wall-to-wall), more biodiverse and chemical free.

Clover says PAWS before you reach for poisons

Hi friends! Tick season is surging and it's easy to want to reach for chemical solutions to keep your pets safe. But owners beware! Read labels before you put anything on your furry friends. Would you put it on yourself or your kids? Many tick collars contain Imidacloprid, a neonicotinoid, which is a family of chemicals that have been blamed for bee colony collapse and are banned in Europe. 

My current favorite tick-repelling treatment is PetzLife Herbal Defense, a simple powder that I eat 5 days a month with my food. My collar, (which is the only tick collar I don't loathe) is made by Holistic Family and Pets. These solutions aren't perfect, but I have very few ticks on me. Fortunately, my mom checks me thoroughly every night which is the best way to be sure I am safe.

June 19-25 is National Pollinator Week. Why all the buzz?

• Bees pollinate 75% of the fruit, nuts, and vegetables grown in the United States.

• Native bees are responsible for pollinating many plants endemic to the Americas, including tomatoes and eggplant.

• Over 4,000 species of bees are native to the United States. Honeybees are not—they were brought to the Americas by European settlers.

Is your yard pollinator friendly? Here’s how it can be:

• Do not apply broadcast sprays for mosquitos and ticks, especially synthetic products. Broadcast sprays kill all insects, not just pests. Even organic sprays can be toxic to bees and butterflies.

• If you plan on having an event or are especially concerned about ticks or mosquitos, apply a plant-based essential oil-based spray using a pressurized pump sprayer with a long arm that can get into small spaces. Only spray in early morning or evening when pollinators are less active.

• Plant native plants to support native insect populations. Many insects are dependent on specific plants for shelter and food (think monarchs and milkweed), and many native crops (think tomatoes and eggplants) are dependent on native insects for pollination.

• Plant host plants, not just flowers. Before you can have a garden full of butterflies, you need to provide a food source for their caterpillars. Keep in mind that these plants will get munched, but you might not even notice the damage.

• Pollinators get dehydrated, so provide a water source for your bees and butterflies. To prevent your bug bath from becoming a mosquito breeding ground, change the water frequently.

Atrazine is the second most widely used pesticide in the US (after glyphosate), with over 73 million pounds applied each year. A common agricultural pesticide, atrazine also is used on turf for broadleaf and grassy weed control. Because atrazine kills cool-season grasses like Kentucky Bluegrass, it is primarily used on lawns in warmer climates (ie. the Southeastern United States).

In humans, atrazine has been linked to:
• Endocrine disruption (what does this mean, anyway?)
• Cancer
• Birth defects and reproductive disorders
• Neurological effects
• Kidney and liver damage
• Eye and skin irritation

How are people exposed to atrazine? Not just direct contact with treated lawns, fields, and food. Atrazine is found in 94% of drinking water tested by the USDA, usually spiking in spring and summer months when it's most heavily applied. Even at extremely low levels, atrazine can interfere with human hormones, fetal development, and fertility. The European Union banned its use in 2004 over concerns that it is a groundwater contaminant.

What is endocrine disruption?

Your endocrine system is the set of glands and hormones they produce (such as estrogen, testosterone, and adrenaline) that help guide your development, growth, and reproduction. Some chemicals—known as endocrine disruptors—mimic your hormones, block hormone absorption, or otherwise alter the concentration of hormones in your body. Endocrine disrupting chemicals have been linked to ADHD, Parkinson’s disease, Alzheimer’s disease, cancers, diabetes, cardiovascular disease, obesity, early puberty, infertility, and other reproductive disorders.

Maybe you've seen beneficial nematodes for sale at your local organic gardening center. Or heard about nematodes attacking the roots of your neighbor's tomatoes. What's the difference? And what are nematodes, anyway?

Nematodes are round, threadlike organisms that eat organic material—from bad bugs and bacteria to plant roots—in your soil. Like the bacteria in our bodies, soil nematodes can be helpful or harmful, depending on the type and number present. A healthy balance of nematodes is key to the health of your soil's ecosystem.

Good nematodes:
• Break down soil nutrients so that plants can easily absorb them
• Eat pests like grubs, bad bugs, and fungus
• Harmed by synthetic fertilizers and pesticides

Bad nematodes:
• Eat plant roots

Want to make your soil friendly for beneficial nematodes? Make sure it is well-aerated; nematodes need plenty of space to move around. Kicking the chemical habit and adding compost to increase organic matter will help balance your soil's biology. When your soil biology is healthy, the less-desirable nematodes—and other pests—will be kept in check naturally.
