Organic gardeners pay very careful -- some say obsessive -- attention to their soil to produce fruits and veggies that they claim taste better than supermarket goods. Organic gardeners can be really into worms, too -- take this quiz and find out why.
Your average backyard soil contains about 5 percent organic matter. One of the goals of organic gardening is to increase this percentage.
Nitrogen is a crucial nutrient, but if the plants don't use it all, it can leach out of the soil and cause pollution. So organic gardeners have to perform a very delicate balancing act with their soil's nitrogen levels.
Compost is an essential part of any organic garden. And you can't just dump your leftover food on your garden and call it a day -- most organic gardeners have a very detailed composting routine.
Regular old compost is not enough for serious organic gardeners -- they use worms to kick things up a notch. The worms eat the compost, and their poop and mucus makes the mixture even more nutrient-rich. A little gross, but true.
Regular old worms just won't do, of course. Red wigglers are especially good at eating our rotting food and converting it into soil nutrients.
Wow, organic gardeners really do like their worms, don't they? Worm tea is water-soaked and oxygenated worm droppings. When you spray it on your plants, it's an insect repellant, fungicide and soil conditioner. And you can even feed the tea back to the worms to create even more good bacteria. Whoa.
Dried blood (usually from horses and poultry) is one of the most effective organic fertilizers, in part because of its nitrogen content.
Hydroponic gardening -- using water instead of soil -- can be nonorganic, too, but the practice has taken off recently among organic gardeners.
Unfortunately, there is no magic organic mixture that kills all weeds. Your best bet is to attack preemptively with careful mulching and garden planning, then pull or dig up any weeds you see as soon as possible.
The White House garden contains more than 50 kinds of veggies, but the President apparently couldn't stand the thought of beets being among them.
