What is vegetation type or zone type, and how is it used?
Vegetation type is used to help determine watering durations. Each vegetation or plant type has a different crop coefficient, which is used in determining evapotranspiration. The higher the coefficient number, the more water the plant uses.
Good news - zone vegetation types now have an option for vegetable gardens!
Why do I need to enter my vegetation type for each zone?
Vegetation is used initially to determine watering minutes for your zones. Each vegetation or plant has a different crop coefficient, which is used in determining evapotranspiration. There may be several crop coefficients used for a single crop throughout an irrigation season depending on the crop’s stage of development. The higher the coefficient number, the more water the plant uses.
To double check your vegetation selections, see the description for each vegetation type below:
Annual Plants go through an entire life cycle from seed to flower and back again to seed within a single growing season, All roots, stems, and leaves die on an annual basis. The dormant seed then will bring the plant back to life next season.
Cool Season Grass
These grasses grow best when temperatures are between 65-80 degrees F, which is why they do most of their growing in the spring and fall. The most common grasses in this category are Kentucky bluegrass, perennial ryegrass, tall fescue, and fine fescue.
Warm Season Grass
These grasses are originally from sub-tropical regions, which is why they thrive in the hot temperatures of the Southern US. The major grasses in this category are Bermuda grass, centipede grass, St. Augustine grass, bahia grass, and zoysia grass.
Perennial Plants generally live more than two years. The term is also widely used to distinguish plants with little or no woody growth. Common perennials include Forget-me-nots, Lavender, Alstroemeria, and Catmint.
Shrubs are generally medium sized bushes that stay less than 20 inches tall. Examples include Azalea, Wintergreen, Hydrangea, Roses, Arborvitae, etc.
This is a catch-all for trees that require significant watering. These could be fruit trees, palm trees, aspen trees, etc.
This is a catch-all for trees that do not require much water and tend to be very drought resistant. Examples include Evergreens, Yucca, Bur Oak, Kentucky Coffee Trees.
This is a general category for fruit and vegetable gardens. Plant examples include tomatoes, carrots, watermelon, beans, and other tasty vegetation.
