Easy Organic Vegetable Gardening: Green Manure, Compost & Companion Planting

Simple, Natural Techniques for a Healthy Vegetable Garden

Organic gardening means using only natural products and methods to grow food, ensuring your harvest is free of harmful chemical residues. These four straightforward practices—green manure, composting, mulching, and companion planting—will boost your soil health and yields with minimal effort.

Green Manure: Growing Your Own Fertilizer

Green manure involves planting specific crops to improve soil fertility. Sow winter rye in fall; it prevents erosion, adds organic matter, and can be cut for mulch before spring planting. Comfrey, a deep-rooted perennial, mines nutrients like nitrogen, potash, and phosphate from the subsoil and releases them when cut and turned under.

Compost: Black Gold for Your Beds

Finished compost is a nutrient-dense humus that enhances soil structure, moisture retention, and disease resistance. Create a pile or bin with weeds, grass clippings, wood chips, and kitchen scraps. As material decomposes, shovel the finished compost onto beds or turn it in. Worms will naturally incorporate surface-applied compost over time.

Mulching: Conserve Water, Suppress Weeds

A thick layer of organic mulch—straw, dry grass, wood chips—blocks sunlight from reaching weed seeds, keeps soil cool and moist, and slowly breaks down to feed the soil. Apply several inches between plants, keeping mulch away from stems to prevent rot.

Companion Planting: Nature's Pest Control

Strategic plant pairings enhance growth and deter pests. Garlic acts as a natural fungicide and improves flavor of beets. Beans fix nitrogen for heavy feeders like corn. Melons and squash shade the soil around corn, conserving moisture. Avoid planting tomatoes near carrots, as they stunt carrot growth.
