Raspberries are a member of the genus Rubus and are sometimes, along with blackberries, called brambles. Raspberries are either red (R. idaeus L) or black (R. occidentalis L) and their growth habits are either erect or trailing. While the red raspberry is native to Asia and North America, the black raspberry is uniquely American, thriving particularly in the east and west regions of the country. Raspberry plants are easy to propagate from cuttings taken from new growth in early summer.
Pour equal parts of sand and potting soil into the planting pot and water it until the water runs out of the bottom of the pot. Drain the pot completely.
Cut a branch from the raspberry bush that has the diameter of a pencil. Cut this branch into 4- to 6-inch pieces.
Plant the cuttings 3 inches deep.
Place the cuttings in an area that is protected from direct sunlight and wind until they root. Use the misting bottle to mist the cuttings with water and keep the soil moist until the cuttings root. You will know this has occurred when there is new growth.
Choose a site in which to grow your raspberry bushes. It should be one that receives at least six hours of sun per day.
Prepare the soil by adding a 3-inch layer of compost, a 2-inch layer of sand and a slow-release 10-10-10 fertilizer (according to the rate suggested on the package) and mixing them into the soil to a depth of 12 inches.
Plant the red raspberry bushes 2 feet apart and the black raspberry bushes 2 and 1/2 feet apart. Erect-growing raspberry plants, in both colors, should be planted 3 feet apart. If planting in rows, space the rows 10 feet apart.
Water the cuttings until the soil is moist to a depth of 6 inches and keep the soil moist until the plants are established, which should occur within one month. Provide the raspberry plants with 1 inch of water after that.
