We moved here 3 years ago and the 20x30 garden was in place, this year as I was transplanting my tomatoes, using a post hold digger to get them deep into the ground, I found charcoal bits about 2 feet down.
I've read they are good for the soil but am surprised they are so far down.
The first one foot of soil is dark , (in the back ground) below the soil is red clay but has these charcoal bits, (marked with the white stake) I'm happy but don't understand why they are so far down ? Can not find any in the upper level ? Dwight
