Composting is a popular tool used by many gardeners to improve soil integrity and the quality and quantity of their plants. “It adds texture and nutrients to soil and helps it retain moisture during dry periods,” said Russ England, a master gardener who manages the compost bin for Gardens on Green. England, in fact, conducts a weekly compost lesson as part of the Hall County School Systems curriculum “Lifecycles: Knowing what to grow and eat” to second-graders.
