Well... I've hauled about 250 lbs of scale infested cactus to the dump, pruned and white washed some fruit trees that were heavily neglected, and got back the results of my soil test for my new property.

Sadly my soil is in a city that is "worst" in the state for agriculture and on my property is harboring dangerous levels of lead, arsenic, and other heavy metals from tailings (mining runoff). So... I've decided on raised beds.

That being said, as I'll be carefully growing my food in Birdie raised beds, I still want to help remediate the soil. Does anyone have experience?

Obviously it's a multi year effort. I'm thinking laying mulch in the form of wood chips or straw between the beds, watering to help break down, then cover planting a plant that helps uptake the harmful chemicals / heavy metal and then removing to the dump and starting the process over? Thoughts?

Yeah that's one strategy. You'll want plants that are very water-thirsty. Indian mustard, sunflowers, willows, water hyacinth...things like that will get the job done fastest. Plant and sequester those every year for maybe 3 years and then retest to see if its making headway. If not, then more contaminants are upwelling from the ground and the area is effed.

Thank you so much for the advice!

Luckily we know that the tailings from the mine are now contained, it's just this horrible quest to fix it. Since I'm so rural (150 miles from the nearest city or other town) I'm really hopeful that if my method works out we can adopt it in the community and all collectively help rejuvenate the earth and make healthy dirt to grow the food we all desperately need.
