Is it true that evergreen pine trees, when planted in a landfill, will acually remove the poisons from the garbage from the ground and help to purify the earth. I forget where i heard this.

Any plant life will help purify lots of the things in a landfill...those that are biologically useful to plants. Provided, of course, the landfill does not contain grass clippings laced with weed killer which will kill the trees, and make them non-functional everybrowns.

In general tho the organics have to decay (by molds and bacteria) to release the nutrients for the evergreens to use, and so no real special benefit to the landfill. Just looks a lot nicer.

I've read that a well-established root zone from trees, shrubs and other native plants can consume large quantities of landfill gas (even when the plants are dormant).

Grasses help stabalize the landfill surface and prevent runoff of toxins

The revegetation of landfills across the country is becoming increasingly accepted and when done properly has benefits not just for the landfill but for the plant and animal life as well.

That way, the landfill can become useful in other ways.

I doubt that.
Perhaps they will grow because of the garbage, and of course trees are suspose to help the air......but in a garage dump I would doubt it....would work out that way........unless it is a very small garbage dump!
