How long does poison last?
I am renting (for the first time in 28 years) and as I was asking the landlord if it was OK to put in a garden, he said sure, that a previous tenant had grown an herb garden there and when they left he 'just poisoned it'!
The restraint that I exercised at that moment impressed even me.
My question is, how long does poison last? I'm suspecting that this rape occured about 2 years ago, and was probably RoundUp. I plan to lasagna garden, toting my own chicken litter, thank you very much!
