the barrier row

I'm planting a "barrier row" of herbs which had, up until this point, consisted of transplanted silver edge thyme, transplanted cilantro and parsley (both spent and useless), dill, and lemon balm. Today I finished up the row and planted parsley and cilantro seeds in the remainder. There is still room at the end for more, but I can't imagine I will want to continue planting herbs. Rather, I would like to throw down some annuals and follow them with ground cover in a bid to reclaim the lower patch of my front yard from noxious weeds. But in the mean time, I should be able to harvest parsley and cilantro by early Fall.
