The least toxic way to deal with weeds is to get them before they flower and go to seed. Go on a weed hunt weekly to see what invaders have entered your yard and garden. Many weeds will resprout if you take off their tops; you have to pull out the roots to make sure they do not come back.
Weed seeds need light to germinate. If you like to till your garden, till it, let it lay for a few days, come back and hoe off the little weed sprouts, then plant.
I like to plant all my veggies in mulch. You can use bark mulch or straw mulch. You can also use pine mulch, but I would use this only around acid loving plants. Do not use hay for mulch as hay has tons of seeds in it!
Another non-toxic strategy is flame weeding. You can buy a flame weeder that you use to burn off the weeds.
A final non-toxic strategy is to cover the area with plastic and let it lay for a season. The heat will kill the weed seeds.
There are also organic weed killers (herbicides) available. You can go to the OMRI site to see what weed killers are considered organic: http://www.omri.org/omri-lists
Some that are out there are from Safer, Matran, GreenMatch EX, Weed Zap, BioLink Herbicide, Whitney Farms weed killer, Avenger Organic Weed and Grass Killer. There are many others as well.
