Yaāll might wanna grow some hyperaccumulators (such as sunflowers, oyster mushrooms, mustard greens, vetiver, etc) around your house and/or in your garden for a few years before you plant leafy vegetables so you donāt end up consuming heavy metals.
If youāre uncertain, most state universities have soil testing labs that offer cheap, easily understood soil tests that can tell you for sure whether youāve got lead, arsenic, etc. in your soils.
searching for āuniversity extension soil test [your state]ā will probably turn up helpful info!
This is a good thing to note, (also sunflowers are very pretty and easy to grow when youāre first learnign how to garden) but also searchingĀ ā(nearest university) Extensionā andĀ ā(your county) Extensionā is GREAT because thereās ALL KINDS of cool services out there if you want to get into growing your own food or helping the local enviornment or installing solar panels on your house or buying livestock or- Thereās a lot, itās AWESOME, itās usually stunningly low-cost and itās veyr, very solarpunk so I encourage all of you to take a gander at the programs offered.
The Cooperative Extension System is run in each state by the stateās land grant university/ies (which might not be the ones you think, in NY itās Cornell rather than any of the SUNYs): https://en.wikipedia.org/wiki/Cooperative_State_Research,_Education,_and_Extension_Service#Cooperative_Extension_System Itās also where all 4H programs are based!
Some also offer classes! Theyāre taxpayer funded, so that means the wealthy ones can offer tons of resources. If you canāt find much going on in your state, nearby states may also have excellent info that can apply to your area. Some of the famous heavyweights are Cornell / New York and UC Davis / California, tons of research, plant breeding programs, and all around useful info coming outta those places.
As a botanist Iām contractually obligatedĀ to addĀ this anyĀ time I see posts aboutĀ phytoremediationāif you doĀ this you CANNOT letĀ the sunflowers/msuhrooms/etc decompose back into your garden. You cannot addĀ themĀ to your compost pile. That just putsĀ the heavy metals right back into your soil!!!! You needĀ to bagĀ them up and dispose ofĀ them elsewhereātraditional landfill waste is probably goingĀ to be easiest for most people.
These plants ACCUMULATE metals.Ā They do NOT breakĀ them down. Youāre pullingĀ them up fromĀ the ground and storingĀ them inĀ the plantĀ tissue, so, donāt consume or compostĀ thatĀ tissue afterwards.Ā
