Our gardens rely on the soil to provide a medium for plant growth. Soils have different properties that determine how rich in nutrients or poorly drained they are. When selecting and preparing a garden site, be sure to determine the current soil’s properties. Don’t guess, soil test to see the levels of nutrients present and learn which amendments are recommended to improve the soil. Gardeners can work to increase the amount of organic matter within the soil by using organic mulch, adding compost and using minimum tillage practices. All of these smart practices help promote “the life” within the soil – the microorganisms and fauna that are a necessary part of healthy soil.

The foundation of a healthy soil relies on a soil management plan. Smart fertilizer use begins with creating a long-term plan for your garden that will build a sustainable soil system. The life within the soil requires food, water, shelter and the proper environment to survive and reproduce. Smart gardeners can help to supply these requirements by providing additional organic matter to the soil.

Organic matter can be increased through various methods. One way is to simply apply a layer of organic mulch around your plants. The organic mulch creates a layer that protects the soil’s surface, therefore regulating soil temperature and moisture and helping with weed control. It also provides a shelter for insects and worms to live in. Organic mulch is a food source for microorganisms like bacteria and fungi that will, over time, break down the components of the mulch and convert them into usable nutrient forms needed by plants.

Apply at least a 3-inch layer of organic mulch around your vegetable plants. Continue replenishing the mulch throughout the growing season. Examples of organic mulch include shredded leaves, grass clippings and bark chips. Be sure to never use black walnut leaves or tree parts as they contain the substance juglone that prohibits the growth of many vegetables.

Gardeners can also create a source of organic matter through the process of composting. Creating compost and adding it to your garden soil is a smart practice. View the “Science of Composting” video to see exactly how to construct and manage a three-bin system. Make use of vegetable scraps within your kitchen, yard and garden residue to build a compost pile. Depending upon what type of composting, the organic matter produced via composting can be added back to the garden in three to six weeks.
