Row Cropping Vs. Intensive Cropping

Home gardens typically adhere to two basic designs:
Row Cropping vegetables are planted in single file rows with a walking path between each row. This layout is especially effective for larger gardens, and allows space to use mechanical tillers and for weed control. The drawback of row cropping is that fewer vegetables are planted in a given area, making it less suitable for small gardens.
Intensive Cropping vegetables are planted in wide bands from one to four feet across. The closer spacing of the plants usually necessitates hand weeding. Because of this, the width of the bands should not exceed easy reach. Intensive cropping allows for more flexible garden layouts. Many gardeners will leave certain areas unplanted initially, allowing additional crops to be planted and harvested later in the season.
Upkeep

Vegetables generally require a steady supply of water. If you have indoor/covered plant containers or if rain isn't plentiful, you'll need to handle watering detail. Always water when the topmost inch of soil is dry. In-ground crops may require watering once or twice a week, while faster-draining raised beds or containers will likely require watering every other day.
For maximum results, consider applying a packaged vegetable fertilizer. Always follow the provided instructions and avoid applying more than the recommended amount. If you are planning an organic garden, you'll want to dig in high quality compost during the initial planting. Organic fertilizers may also be used if desired.
Weeds are the bane of every gardener: they compete with your vegetables for nutrients and water. Discourage weed settings by using a hoe or hand fork to regularly stir the top inch of soil (this is known as cultivation).
