Cement next to my garden. Any chemicals leach into plants?

by Lisa

Is it safe to plant next to my cement patio, or could the cement leach a chemical into plant? I want to plant blueberry bushes/raspberry bushes and don't want anything going into the bushes, and therefore the fruits?

Concrete safe for garden
by: Megan

Concrete is safe and happily used by millions of gardeners worldwide next to their plants. Concrete is mostly sand and cement, which is a natural mineral anyway.
There is apparently a possibility of minute amounts of lime leaching into surrounding soil, which in most gardens would be beneficial, but don't plant acid loving plants within about 15cms from concrete. Berries are acid loving so as a precaution add some wood chips, pine needles, leaves or sawdust.

Cement contains heavy metals
by: Lara Harding

Hello, you might like to inveztigate fly ash, which is now used in cement. It is a waste product from coal fired electricity plants. There are lots of studies into leaching into soil. I am not sure what the level of risk is. Best to look into it. Flyash contains heavy metals.
