Hemp grows on every continent except Antarctica, with commercial production spread across more than 30 countries. The largest growing regions are in China, Europe, Canada, and the United States, though the plant is remarkably adaptable and thrives in a wide range of climates and soils. Whether you’re curious about global production or wondering if hemp can grow where you live, the answer is probably yes.
China: The World’s Largest Producer
China produces over half the world’s hemp fiber supply, making it the single biggest grower on the planet. While hemp is planted across the country, production concentrates in four provinces: Heilongjiang in the far northeast, Yunnan in the far southwest, and smaller operations in Anhui and Gansu. The modern Chinese hemp industry is only about a decade old despite the plant’s ancient history there, and it scaled up rapidly to dominate global output. Heilongjiang’s cold, fertile plains suit fiber production, while Yunnan’s subtropical climate supports different varieties.
Europe’s Dominant Role
Europe is the largest hemp-producing region in the world when measured collectively. EU production hit 179,020 tonnes recently, an 84% increase over the prior period. France alone accounts for more than 60% of all European hemp, followed by Germany at 17% and the Netherlands at 5%. French hemp cultivation centers in the northern regions where the climate mirrors the cool, temperate conditions the plant prefers. Dozens of other European countries grow smaller quantities, and EU agricultural policy actively supports hemp as a sustainable crop.
North American Production
Canada was one of the first Western countries to re-legalize hemp in 1998, and it became a major supplier to the U.S. market for years. Canadian acreage has fluctuated significantly: about 76,900 acres in 2022, dropping to 55,400 in 2023, and falling further to roughly 36,500 acres in 2024. Manitoba is the leading province, with about 14,000 of those acres. Saskatchewan and Alberta also contribute significant production, mostly focused on hemp grain and seed for food products.
In the United States, hemp cultivation expanded after the 2018 Farm Bill legalized it federally. Production now spans dozens of states, with notable acreage in Kentucky, Colorado, Oregon, Montana, and New York. American growers cultivate hemp for fiber, grain, and cannabinoid (CBD) extraction, with the crop mix varying by state and market demand.
Where Hemp Grows Wild
Feral hemp, sometimes called “ditch weed,” grows wild across the American Midwest. These populations descend from industrial hemp planted decades ago, before prohibition, and they’ve persisted without any human care. Nebraska, Kansas, and Colorado all have documented feral populations, and genetic analysis shows they carry significant variation from adapting to local conditions over generations. Some of these wild American plants cluster genetically with older European fiber varieties, while others more closely resemble landraces from China.
The most suitable wild habitat runs along low-lying river channels and tributaries, particularly the Upper Mississippi, Ohio, Missouri, and Platte Rivers. Hemp naturally gravitates toward the rich, well-drained soil and consistent moisture found in river valleys. These feral populations contain no meaningful levels of THC but remain technically regulated in most states.
Climate and Soil Conditions Hemp Needs
Hemp is a warm-season annual that needs roughly 100 to 120 frost-free days depending on the variety. It germinates best when soil temperatures reach about 46 to 50°F and grows most vigorously in daytime temperatures between 60 and 80°F. The plant tolerates a wide pH range but performs best in well-drained soils with a pH between 6.0 and 7.5. Heavy clay soils that hold standing water are one of the few environments where hemp struggles.
Water requirements are moderate but not trivial. Research from Oregon State University found that CBD-type hemp responds to irrigation up to about 25 to 30 inches of total seasonal water, with yields increasing steadily across that range. In regions that receive 20 or more inches of rainfall during the growing season, hemp often needs little or no supplemental irrigation. In arid climates like parts of Colorado or eastern Oregon, irrigation becomes essential.
Growth Timelines by Crop Type
How long hemp takes to mature depends entirely on what it’s being grown for. Fiber hemp is the fastest, reaching harvest in about 70 to 100 days after planting, typically in late August to early September. Grain hemp takes longer, with harvest running from mid-September to early October. CBD hemp is the slowest, requiring the full growing season and typically harvested from September to mid-October to allow cannabinoid concentrations to peak in the flowers.
These timelines mean that hemp fits comfortably into the agricultural calendar of most temperate regions worldwide. In northern latitudes like Canada and Scandinavia, shorter-season fiber and grain varieties work well. In warmer climates with longer growing seasons, farmers can choose from a wider selection of varieties including those bred for cannabinoid production. This flexibility is a major reason hemp cultivation has spread to so many different countries and climates, from the subarctic plains of Heilongjiang to the Mediterranean coast of southern France.
