Soil preparation
The first step to organic gardening is to prepare a base of fertile, healthy soil. Healthy plants draw their nourishment from healthy soil and thus are less susceptible to diseases and pest attacks. Create healthy soil by adding natural organic matter such as compost and manure.
Fertilizer
If you need fertilizer, use naturally occurring organic fertilizers such as bat guano, blood meal, bone meal, fish emulsion, cottonseed meal, green sand, rock phosphate and soybean meal.
Plant selection
The next step is to choose the right plant for the right place. For a naturally moist area, select plants that like moisture. In a sunny spot, choose plants that thrive in heat and sun. In either case, you save water, and the environment thanks you. Select Plants of Merit and native plants appropriate for our area. Plants that live in conditions that suit them require less maintenance and are less likely to succumb to diseases and pests. Many disease-resistant varieties of flowers and vegetables are available.
Cultural weed control
In nature, all weeds are plants. When these plants escape their natural environment and controls, however, they create problems and become weeds. Even the best garden probably has some weeds.
The trick to prevent weeds is to keep them from sprouting. To do that, keep their seeds from reaching sunlight. Good barriers to weed sprout are mulches such as pine straw, shredded or chipped wood, or pebbles. Ground covers such as Mazus reptens, Lamium or Ajuga, acting as living mulches, are even more effective. They prevent weeds from seeing light, prevent soil erosion and keep the soil moist, once again saving water.
