@Matt LiuWhen you use theDiotemacous Earthyou must use the food quality variety, that is used on fruits, vegies and grains and it will be non-toxic to humans.

One other thing to think about is, given that all the properties are on one street, is that all of your eggs are in one basket.

Don't put all your eggs in one basket.  

Like planting seeds that come up later and bear fruit.

Love itAnd if this post doesn't provide any fruit i'd suggest you contact the top players in your area saying exactely this to them.
