Upon returning home from a 2-week vacation, I found the earth berms around our resident with an "infestation" of moles .. a spiderweb of tunnels going in every direction. I went on the internet and found that introducing a mixture of ammonia and bleach was an effective way to kill gophers (creating chloramine gas when mixed). I carefully placed these chemicals into the berms to get rid of the moles. The chemicals were placed in the berms about one week ago. QUESTION: Would you consider it OK to plant a garden in the locations shown in the attached illustration, i.e., one garden bed about 27 feet away from the application area; the primary garden about 75 feet away on the other side of our yard?
