If the weeds have dropped their seed, the damage is done. However, if they haven't or much of the seed head is still on the plants, you may want to try to mow/weed wack the plants to remove the seed heads. It will take some work but will save time next year - been there.... done that and doing that!!! /w3tcompact/icons/mad.gif We made the mistake of getting some horse manure than had not fully composted and we have been fighting a battle with the weeds. /w3tcompact/icons/shocked.gif
Just for grins, take a close look at the seed heads of the weeds. Most weeds develop thousands of seeds. If the seeds have already matured and dropped, fold back the plants and see how much seed is on the ground. It is amazing!! /w3tcompact/icons/shocked.gif
If you choose not to remove the seed heads, I suggest that you still mow or bush hog the weeds. Once the weeds have set seed, typically the stalks are drier and tend to get wrapped up in the tines of your tiller. By chopping them up, your tiller will incorporate them into the soil without fouling the tines.
Mulching between the plants and especially in the rows between the plants is important. Since we are growing a lot of vegetables and herbs to sell, we have begun to use silt fabric between the rows. This has lessened the amount of work for us. Our rows are 50 ft long to accomodate the soaker hoses and we cut and sealed the silt fabric at each end so that we allow only 6-9 inches of exposed soil for the plants. We get weed protection and moisture retention with this method. The fabric comes in widths of 2, 3, and 4 ft. We have located a source in Georgia and buy the stuff in long rolls and they also can provide the long staples to hold the fabric to the soil. This fabric is pretty tough and will last a few seasons - i.e. much better than black plastic as it allows moisture to seep into the soil. This method is not 100% effective as weed seed will germinate if the seed is on top of the fabric. However, the weeds can easily be removed.
The battle to control weeds is never ending and takes time to get the problem under control. Cultivation and hand weeding are the best solutions to get control. A side benefit (depends on your view, of course), is that you can spend a few hours doing mindless work to leave all of your troubles behind you. Also, if you get the family involved, it provides for some "quality" time to just work at a leasurely pace and talk. You also begin to see some of natures amazing plants and creatures at work - watch lady bug nymphs munch on aphids, soldier bugs stalking, different spiders and mites, etc.
