Even if such plants remain alive and free of infectious disease, they will not yield as much as strong and burly plants. When there is no other choice for a garden site but a heavy, wet soil, plant in raised beds or ridged rows so the soil around the plant's roots will be drier. Heavy wet soils discourage healthy root growth and encourage root roots. When a garden is established on sloped terrain, plant in terraced beds to reduce soil erosion over delicate, young plants and newly sown seed. A soil environment that is favorable to healthy root development will support the growth of healthy plants.
Plants require one inch of rainfall per week for best growth.
If rainfall is inadequate, water the garden. Also avoid using overhead, sprinkler irrigation because it can promote the development and spread of leaf, flower, and fruit infections. Trickle irrigation is best because it puts water directly in the root zone, does not wet the plants above ground, nor encourage soil splashing. Plants that are fertilized properly at planting time and as a sidedress will grow better and healthier. Always use a complete fertilizer or incorporate a well-rotted manure or rich compost into the soil.
