For framers in Wisconsin who are interested in entering the world of hemp growth, there are numerous factors to take into account. We hope you find the guide below useful on this front.
Plant Hardiness Zone(s)
Hemp plants are generally considered to be low maintenance, although, this is naturally dependent on conditions being as close to ideal as possible.
The typical soil temperature in Wisconsin is around 18 degrees Celsius. Would this be suitable for hemp plants to thrive? It certainly could be. Hemp plants tend to like a soil temperature of above 12 degrees Celsius. Often their preferred thermal conditions are noted to be between 12 to 14 degrees Celsius, hence while Wisconsin comes in a little higher than this, the difference is not colossal.
Length of Growing Season
Wisconsin has a healthy growing season with the first day of the frost-free growing season commencing on May 2 and the end of the growing season being October 6. This gives a total of 157 days. This length of growing season is more than adequate for hemp plants to grow, in fact, some varieties only need a short season and can even thrive when planted in the month of June.
Average Annual Sunlight
Wisconsin receives 2428 hours of sunlight each year. Per day, this is approximately 6.38 hours. Since hemp plants need around a minimum of 6 hours sunlight each day, Wisconsin comes within the mark.
Average Annual Precipitation
Wisconsin has a relatively high level of annual rainfall with a figure of approximately 87 cm per year for annual precipitation. Hemp plants, being relatively hardy, only need between 25-30 cm of rainfall each year.
The highest elevation points in Wisconsin reach over 1,900 feet above sea level. Other high elevation points include Mt. Whittlesey and Meteor Hill, each of which is over 1,800 feet above sea level. The lowest elevation areas are found along the shore of Lake Michigan, here elevation is 579 feet above sea level. Hemp plants do not tend to like overly high areas of elevation, in fact, they will thrive when they are grown at locations that are at or below 800 feet above sea level.
Hemp plants thrive when the pH level is between 6.0 and 7.5. There are areas of Wisconsin where sandy soils have a pH of lower than 5.0 which would naturally make these areas less attractive for hemp flower growth.
Hemp plants thrive when the soil they are planted in is well-aerated. Wisconsin has a huge variety of soil depending on the where you are in the State. To the North, there are many areas of forested and loamy soils whereas the further South you go the soils become siltier.
Virtually every plant species is susceptible to various types of pests, and hemp flower is certainly no exception. Some of the pests which are common in Wisconsin are aphids, the Black Cutworm, caterpillars, and the Aster Leafhopper.
Obtaining A Hemp Flower Grower’s License In Wisconsin
Under federal law, it is illegal to grow hemp flower anywhere in the United States without first obtaining a grower’s license from the appropriate regulatory body for the state in which the interested party intends to plant the crop.
