Once a year I go buy fresh cow manure from a farmer. I spread the manure in my three flower beds in my front yard. I then pile some in a wheelbarrow and leave on side of house. I leave the rest in the trailer on the other side of the house. I also give some to the guy next door. Then each year I go around to each neighbor and ask if the want some free manure for there beds. I just say I bought way to much again. If the take some it spreads the manure smell even more. If the say no it still lets them know where the smell is coming from.
You want fresh manure not composted manure. After harvest dump the rest in your garden and till in.
This is the only solid way I have been able to mask large backyard grows. Just give the wheelbarrow and trailer a stir every day. People walking by just smell the manure in my flower beds right by the street.
Manure is cheap at the farm. I think you can buy it in bags but not sure on fresh. The bags may be composted. I only used fresh and it's ripe. If you can deal with the manure smell this will work and is a solid cheap way to mask the grow.
