I don't understand why people clear a space of all vegetation with horrible poison like RoundUp, then in-turn attempt to cultivate edibles in the same space.  Good soil is alive...full of organisms, earthworms, and bugs.  It moves, breathes, and supports our very lives by supporting the green things we REQUIRE to survive.

Rob and I spent several weeks this last month manually removing nearly a hundred gallons of dandelions from the front yard.  I then used a turkey baster and squirted horticultural vinegar (get it here) in the holes left by the removed dandilions to ensure the destruction of the gargantuan tap roots that dandelions have.  Horticulture vinegar is 20% acetic acid.  It kills the hell out if whatever you put it on, but it does not stay in the soil.  It will not harm soil!  I then overseeded with nitrogen-fixing micro-clover and grass seed.  The clover has sprouted already...still waiting on the grass seed.  I will post pictures in a few weeks after the first mow.

Please stop using poisons like RoundUp!  Yeah, for sure it is hard work, but the soil is still dark, full of worms and bugs...and will support any and all plant life.
