Garden Advice – True or False? Compost Tea Helps Plants and Soil by EMG JennFor the next few weeks on Fridays, we’re going to explore common garden advice and myths and whether they are supported by scientific research. Today’s topic: the murky world of compost tea. Many books and websites will tell you that you can steep compost in a bucket of water to make an elixir that will feed your plants and your soil. Sometimes the mixture is aerated by bubbling water through it; sometimes additional sugars like molasses are added. Is this a good idea?Compost itself is a great idea! It contains beneficial bacteria and fungi as well as nutrients. If you think your soil is deficient, adding compost will help. Compost not only provides these organisms, but its structure gives them water, nutrients, and air, so they flourish.

Better to use straight compost! What about using compost tea as a foliar spray? Yes, to a limited extent, it can work, but if you have bad bacteria in your compost tea and spray it on fruits or vegetables, it can make you very sick!Want to read more?
