I have heard this complaint for about as long as I have been aware what organic gardening meant. What always amazed me is that when I was growing up, we were organic out of necessity. We could not afford to buy the chemicals that were coming on the market. Sooo, why is it more expensive now?
My belief is that we make it more expensive than it should be because we became accustomed to the 'magic pill' or instant results and therefore have to buy all the trendy things that are on the market. While I might some day open an organic supply shop, the fact is that if you learn true organic methods, you will eventually NEED very little of what I would have to offer.
Organic and sustainable are often used interchangeably. That is because most organic methods can be sustained through natural processes. Short term synthetic fertilizers are trying to feed the plant, but long-term organic approaches seek to feed the soil. Healthy soil feeds healthy plants, which in turn should feed healthy people.
Growing organic takes learning and you can't learn overnight, so have patience. Don't look for the 'silver bullet' and accept that sometimes the dark side wins.
