"Organic" - Is it all that?

A lot of people ask me if I’m strictly an organic gardener. Well, I guess in the strictest sense, I’d have to say no to that. I occasionally have to resort to using glyphosate (better known as Roundup) to knock out stands of poison ivy. Since I’m highly allergic to it, I can’t get near the stuff without breaking out. And sometimes, I’ll even use a little Miracle-gro in my containers when they need a quick shot of soluble fertilizer.

On the other hand, my use of man-made, synthetic chemicals are few and far between. Given the choice I prefer to use fertilizer and pest controls that are organic or natural first. Why do I say this? Because generally, they are kinder to the earth as they are manufactured (if even applicable) and once they are applied to our lawns and gardens.

Synthetic fertilizers are designed to be water-soluble. Contact with water releases the chemical and what isn’t absorbed by the plant (which is most of it), continues to move off target, either as storm water runoff, or through the soil into underground aquifers. Either way, these chemicals can wreak havoc in watersheds, promoting the growth of algae and depriving other amphibious creatures life-giving oxygen and disrupting delicate ecosystems. Organic or natural fertilizers on the other hand must be broken down in the environment first before they are in a form that can be taken up by plant roots. Accordingly, they are slower acting and tend to bind or stay where they’re put, at least much longer than soluble products. And organic / natural products are not manufactured with salts which can really throw off soil pH and disturb the living soil food web.

The very premise of organic gardening is to establish a healthy eco-system, above and below ground. Doing anything to disturb that is counter-productive to organic gardening. So what about tilling? It doesn’t even involve chemicals and would certainly be considered a natural or organic form of cultivation. But it greatly disturbs the soil structure and contrary to popular belief, should be avoided if your goal is to build healthy soil.

Pesticides are the biggest problem in my mind and the major reason why I’m a strong advocate of natural over synthetic choices when it comes to control. But even here, many natural methods are non-selective—my biggest beef with synthetic chemicals. Which is why I don’t spray at all if possible. Instead, I let nature take its course. It does much better than me at dealing with the pests in my garden. Of all the bugs, only about three percent are even considered pests (the ones that actually damage your plants). So why then would you spray any non-selective chemical on your garden when 97 percent are either beneficial or at worst, neutral? You shouldn’t!

But I do like knowing that organic controls are far more susceptible to breaking down quickly in the environment when exposed to sunlight. And I certainly appreciate the biological controls such as B.t and Milky spore that are very pest specific and harmless to other creatures in the garden.

The bottom line though to organic and non-organic, synthetic controls is the fact that no matter what you are using, it should be applied with great restraint, discretion and with the wisdom of knowing how, when and where to apply it. If you have to resort to any chemical, keeping it on target is a major factor in minimizing the environmental impact.
