Start with good compost, give it some water, some aeration, and some time, and you'll have a multipurpose elixir for your garden.
Gardeners all know compost is terrific stuff. But there's something even better than plain old compost, and that's compost tea. As the name implies, compost tea is made by steeping compost in water. It's used as either a foliar spray or a soil drench, depending on where your plant has problems.
Why go to the extra trouble of brewing, straining, and spraying a tea rather than just working compost into the soil? There are several reasons. First, compost tea makes the benefits of compost go farther. What's more, when sprayed on the leaves, compost tea helps suppress foliar diseases, increases the amount of nutrients available to the plant, and speeds the breakdown of toxins. Using compost tea has even been shown to increase the nutritional quality and improve the flavor of vegetables. If you've been applying compost to your soil only in the traditional way, you're missing out on a whole host of benefits.
