Yeah, I'm kind of getting discouraged, too.
We who do not reside in town homes, small apartments, retirement comunities, have no problem. We can use every bit of dirt or lawn to plant veggies and use as a land scaping tool.
In the depression people in the city's raised chickens on the flat roof tops of big city's, some places they still do. Churches are now building comunity gardens to grow food, some towns have set aside areas on vacant lots for people to make a garden.
All good idea except that the amount of food one can plant is most times more expensive and man power to save any money.
The growing season in the north is short, once the harvest is done there are 9 months of the year we have to buy our food.
I remember as a child living in the Canal Zone of Panama, Mom would go to the military stores for food and the number one rule was on coming home dump the paper bag upside down on the table, never reach into the bag. The faint smell of Clorox was on all fresh vegetables. The military would spray fresh vegetables with water and Clorox to make sure it was disinfected.
Today, if you have city sewage no problem, for us with septic tanks we cannot use bleach.
I have a 10 gallon bucket that I fill with ice water and 1/2 cup of bleach and drop fresh produce into it for 15 -20 minutes, remove them and rinse under the tap for 2-5 minutes then dry and store.
The water in the bucket is taken out and dumped on weed patches or areas that cut worms and ants have taken over. Much better then using nasty chemicals on those areas Saves problems with the septic system and seems to drive out the moles.
If in doubt, eat a Kosher diet soak all meats to remove the blood add salt and a few drops of Clorox
If all this does not work, then you have done all you can do and have no choice but to allow nature to take its course.
