For example, Seattle, Washington, and the city of Austin, Texas, are both in the USDA hardiness zone 9a because the map is a measure of the coldest temperature a plant can handle.
Plant density is defined as the number of plants present per unit area of ground. In nature, plant densities can be especially high when seeds present in a seed bank germinate after winter, or in a forest understory after a tree fall opens a gap in the canopy.
Able to annotate maps and print at different scales and import/export files to GIS. Allows an image (scanned aerial photo or map) to be added to the background of a map. Boundaries can then be over-drawn, and areas and distances estimated. Stocking: A planting design tool which links to planting event(s) in the Regime editor.
In 2012 the USDA updated their plant hardiness map based on 1976–2005 weather data, using a longer period of data to smooth out year-to-year weather fluctuations. [7] Two new zones (12 and 13) were added to better define and improve information sharing on tropical and semitropical plants, they also appear on the maps of Hawaii and Puerto Rico.

The above equation is an expression for computing the stand density index from the number of trees per acre and the diameter of the tree of average basal area. Assume that a stand with basal area of 150 square feet (14 m 2) and 400 trees per acre is measured. The dbh of the tree of average basal area D is:
Sowing is the process of planting seeds. An area that has had seeds planted in it will be described as a sowed or sown area. When sowing it is important to: Use quality seeds; Maintain proper distance between seeds; Plant at correct depth; Ensure the soil is clean , healthy , and free of pathogens (disease causing microorganisms)
For example, a single tomato plant takes a full square, as might large herbs such as oregano or basil, while lettuce plants would be planted 4 per square, and up to 16 per square of plants such as radish or carrots. Tall-growing crops are planted or trellised on the north side of the bed (in the Northern Hemisphere) to avoid shading shorter plants.
