Once a week I get my two gallons of compost tea and bring it home to my garden. Compost tea is a nutrient rich brown liquid that is a product of DIY worm composting. I spray it on all my garden areas including my rose bushes and crepe myrtle. Our soil here is a hard pan clay that until I started using compost tea did not support life at all. There are places here that thistles will not grow. With the help of a little worm compost and compost tea I now have a vigorous and thriving garden where once was hard pan.
