My husband mistakenly put fertilizer with a broad leaf killer in it on our garden. Is there anything we can do to grow things this year? Everything has died sadly.



You did not name the active ingredient of the leaf killer, so the residual time in the soil is dependent on what is the herbicide, since there are several different chemicals used for broad leaf herbicides.  Many reside in the soil for up to 3 months, and there is not an environmentally safe way other than soil removal and replacement in the near future if you want to grow something in your garden, other than monocots (those plants that are not broad leaves) so plants that are in the grass family, cereal grains, lily family, etc that are not affected - but not sure since you need to read the active ingredient off the package to see what plants it affects.
