Chives, new garden question
This spring I decided to turn a 1/4 acre weed-plot into a garden. First I rounded-up the whole area. Once it was mostly dead I rototilled it all in. Then watered for a few weeks, then weeded, then rolotilled again. This fall I'm bringing in manure, and rototilling it in, before letting the ground rest until spring.
Now my problem: Much of the area was/is overrun with oregano, mint and chives. Round-up worked on the oregano and mint, but nothing has killed the chives. Now please, let me stress, I'm not talking about a few clumps of cute, little, round fairy-land chives. I'm talking about a patch so large and thick that a big rototiller has trouble breaking ground. They point and laugh at me, drink round-up like it's orange juice, and bloom wildly. I had to mow them, down the fence line, which made the air sickening with a garlic smell (and I love garlic!), which led me to believe they are indeed, garlic chives. Short of shovel digging each small bulb up I don't know how to get rid of them. The ground is very rocky, graveley and hard-pan, so understandably this is the last thing I wish to do.
Any suggestions would be greatly appreciated.
