Because vertically growing plants are exposed, they dry out quickly and may need to be watered frequently. This fast drying is an advantage to those plants susceptible to fungus diseases. A high rate of fertilization may be needed, and soil should be deep and well- drained to allow roots to extend vertically rather than compete with others at a shallow level. Several examples of vertical gardening structures are shown below. Interplanting Growing two or more types of vegetables in the same place at the same time is known as interplanting.

Heavy feeders, such as cabbage family crops, should be mixed with less gluttonous plants.
