I don’t do soil samples either.LOL. I just work in some healthy amount of compost and hope for the best. Sometimes I put some egg shells in the space where I plant tomatoes and melons, and use a little liquid fertilizer when they are blooming and making fruit.
We just threw together this garden patch on short notice. For our main garden this year we did a soil test. The soil was 5.0ph and no nitrogen, so we added what they recommended and had a better crop this year. This little garden area is not to far from our main garden, so I suspect that the soil is pretty useless also. When the season is over, I am going to till in some store bought compost and hope for a better crop next year.
