>i have a driveway that i am transforming in lawn it is made out of the same
> Any ideas?
material than a ram earth builder use here . you can't have more compacted
medium except cooked earth . despite of that, grasses , clover, plantains
chamomille etc.. are transforming this place in a fertile medium .
where my raised beds, that have been established on this driveway , are
leaking some of their contenton the driveway all kind of vegetables,
grasses are growing on their own without me ever having to till the driveway
no machinery could do the work that roots are doing because they do more
than a mechanical work , there is chemical work and also ther is the power
of life to establish itself in the most unexpected places . have you ever
seen huge trees growing supended on a rocky cliff ?roots in association with
the microlife they shelter and nourish have the power of dissolving rocks
.Here on the shore , at the edge of the sea waters there is 3 apples trees
growing and producing fruits in a very smal crevice inside the rock with no
soil at all .I have seen also a pear tree growing that way on a small islet.
