Jocelyn H. Chilvers added this to Weed War: When and How to Use Chemical Herbicides
Natural HerbicidesThe active ingredients in natural herbicides come from plants or minerals. These products are subject to government regulations for personal and environmental safety. Read all product labels thoroughly and follow them with care.Corn gluten meal. The protein part of a corn kernel is a selective, pre-emergent herbicide most commonly used to control annual weeds — such as oxalis, purslane and spurge — in lawns. It’s also about 10 percent nitrogen, so it helps promote healthy turf. Corn gluten meal is most effective when applied twice a year. Apply it before the seed germinates and forms a root. A dry period following germination is also necessary. Learn more about timing corn gluten meal applications here.Vinegar. It's a nonselective, postemergent and contact herbicide for annual weeds. Apply horticultural vinegar solutions, which have less than 20 percent acetic acid, as a spray to the weeds’ foliage. The acid acts as a contact desiccant (“burning” the foliage but not the roots) and is most effective when applied to annual weeds in the heat of summer.Soap. Horticultural soaps, derived from fatty acids, are nonselective, postemergent, contact herbicides. Sprayed on the weeds' leaves, the product smothers the foliage, inhibiting the plants' growth. Horticultural soaps are most effective on young, actively growing, annual weeds.Iron. The newest kid on the block uses a 1.5 percent solution of FeHDTA (an iron chelate) as its active ingredient. A selective, systemic, postemergent herbicide, the applied iron dose is toxic to several common broad-leaf weeds but does not have a detrimental effect on turf grasses.
Marianne Lipanovich added this to Summer Crops: How to Grow Corn
Harvest: About three weeks after the silks appear, the corn should be ready to harvest. Once the silks are brown, slit the outer husk on an ear or two and pinch a kernel; if the juice that squirts out is milky, the corn is ripe. For best results, harvest when the water in the cooking pot is boiling, though some newer and sweeter varieties will hold their sugar longer. If you harvest early, store the corn unhusked in the refrigerator.For baby corn, harvest shortly after the silks appear. For popcorn, wait until the silks and husks are thoroughly dry; rub or cut off the kernels and store them in a dry place.

Sow seeds. Beans, corn, cucumber, garlic, potatoes, shallots and summer squash seeds can be directly sown into the garden right now. In early August, there is still time to sow seeds of okra, black-eyed peas, New Zealand spinach, Malabar spinach and winter squash. Seeds that you can start in flats or pots right now include broccoli, Brussels sprouts, cauliflower, chard, Chinese cabbage, kale and fennel. In late August, collards, endive, mustard and lettuces can be planted in flats. When starting seeds in flats or pots, be sure to give them bright light while keeping them shaded from the strong afternoon sun. Consider using shade cloth over these seedlings to protect them a bit if you are short on shade in your yard.

Love the idea of natural herbicides... but what exactly is "horticultural vinegar" or "horticultural soap" ? Wouldn't any soap or vinegar do just as well?
