Hemp Agronomic Characteristics Hemp is a bast fiber plant similar to flax, kenaf, jute and ramie. Long slender primary fibers on the outer portion of the stalk characterize bast fiber plants. An annual plant that grows from seed, hemp can be grown on a range of soils, but tends to grow best on land that produces high yields of corn. The soil must be well drained, rich in nitrogen, and non-acidic. Hemp requires limited pesticides because is grows so quickly and attracts few pests. In northern latitudes, hemp is usually planted between early March and late May. Hemp averages between 2 - 4 meters in height in about four months of growth. Hemp crops are harvested at different times for different hemp products.
