Danger Used Greenhouse Soil!

A few years back I got some used potting soil from a big greenhouse, big mistake Some of the soil was fertile but it was filled with invasive weed seeds and I think 4 or 5 species were introduced. Secondly some of the soil is just plain screwed and won't even grow grass or weeds right. A raspberry bush grows 6-7 feet tall in the good soil and 2 feet tall in the dead greenhouse soil. Live and learn.

I think the term "soil" is a very generous term for the planting medium used by many commercial growers. This stuff isn't meant to nourish the plants. It is meant to deliver chemical fertilizer to the roots and to hold the plant up.
Jeff is my brother - 18 years younger, they just kept having kids. A couple years back my mother called, wondering if I could convince Jeff to stop digging up the farm. It's a small patch that hasn't really been farmed in 30 years. Last week when mom called on my birthday, she told me that Jeff has food coming out of stacks of wood, rock piles, and every other spot. He has vines climbing trees and he's terraced an eroded hillside. He's feeding my parents and many visitors and sells at a market. My mother - "He sticks his hands into the soil and picks potatoes and artichokes without hurting the plant. People who are into that permaculture cult come to watch and help him and he sends them home with cuttings and roots." What started out as a major battle of wills has ended with my mother conceding that Jeff is really on to something.My parents are old and can't garden 7 acres in a conventional manner and it looks like they won't have to. The food is delivered to the kitchen.
