This spring Missoula Parks & Recreation offered a virtual training event, Organic Lawn Care 101. Healthy Babies Bright Futures and Grow Safe: Non-Toxic Missoula took part in the event led by presenters Jay Feldman, Beyond Pesticides Director, and nationally recognized organic turf expert, Chip Osbourne.
Feldman and Osbourne each have decades of experience with organic practices and deep knowledge about the risks of synthetic pesticides and fertilizers. They are leaders in a national movement to educate and implement safe and healthy land care. Organic practices protect human health, pollinators and wildlife, keep our waterways free of polluted runoff, and sequester carbon, among other benefits.
According to Osbourne, homeowners use as much or more pesticides on their yards than all agricultural pesticide use combined. These toxic chemicals are applied primarily for cosmetic purposes. There is a history here. Synthetic nitrogen and an assortment of chemical agents were developed for warfare. After WWII, industry found alternative uses.
In the 1950s and 60s, industry purposely created an expectation for a mono-culture lawn that has persisted up to today. Picture the suburban development of the 1950s and you begin to see the foundation of our current culture. These expectations were established to sell product. Housing developments sometimes had sales agreements that committed the homeowner to maintain the lawn with specific pesticides and fertilizers.
The average person can stop in at their local garden supply and go home with a vast range of toxic lawn products. That individual may or may not read or understand the safety guidelines. They almost certainly won’t realize that only the active ingredients are tested– and those active ingredients are not registered as “safe.”
Instead, they are tested to establish the level that prevents acute poisoning or immediate death. Pesticide registration does not take into account the effects of low exposure to a chemical over long periods of time. No one is testing the “inert” or “other” ingredients or how a combination of active ingredients may become more toxic when mixed together.
The carbon footprint of using these products is staggering–it takes 5 tons of petro-chemical equivalent to manufacture a single ton of synthetic fertilizer. THere are plenty of reasons to embrace organic lawn care. As Feldman says, “The only option for a livable future is organic.”
We don’t need synthetic products to have a beautiful lawn or yard. Organic land care is not a product-swapping strategy. Instead, it focuses equally on the soil below and the plant we see growing above. Osbourne has many recommendations for growing a vibrant lawn. To start:
Aerate- avoid compaction by using an aerator to bring air into the soil. This gives plant roots space to grow.
Overseed- filling in bare spots and keeping the entire lawn thick will crowd out weeds.
Water- no more than 2” a week at the hottest times of year. Overwatering is one of the biggest problems.
Mow- to 3” height, keep blades sharp, and leave clippings on the lawn.
Compost- introducing organic matter feeds the soil microorganisms. Living organisms support healthy grass.
A Guide to Organic Lawn Care is a free, local resource with step-by-step plans to meet your expectations.
The basis of sustainable, organic land care is nurturing healthy, biologically active soils and always leaving the soil better than we found it. We can have beautiful yards that are also safe.
