Sprawling plants, such as melons and cucumbers, will need plenty of space. Train them up on wire or string trellises or select bush-types. Just remember that yields on bush-type plants will be lower. Very tall plants, such as corn or okra, can also be grown in raised beds. Plant them on the north side of the garden so they will not shade other vegetables.
Corn is a heavy nitrogen feeder.
Plan to follow this crop with a nitrogen-rich legume, like snap beans, to make up for any extreme deficiencies. Pole beans grow well in raised beds and can be intercropped with faster, shorter growing plants such as lettuce, radishes and Chinese cabbage. Bush beans can be grown in a double-wide row for maximum production. Tomatoes will need to be staked or caged. Perennial crops such as asparagus, rhubarb, horseradish and some herbs should be planted in a separate garden.
