Thanks to you guys my spending on nonsense is relatively little.
I’m not organic, so I get one and a half cubic yards of wood chips every year and turn it into compost with a few pounds of urea fertilizer. Soil tests show some micro-nutrients are lacking, so I address that with small amounts of real chemical name fertilizers added to the pile in proportion based on the tests. I don’t get the tests every year.

I started selling some plant material. Once you get going, you have a lot of extra’s. It has helped a lot.
