Raspberries come in several varieties of red, black, purple and everbearing. Chosen for the succulent fruit produced, raspberry plants are a favorite among backyard gardens. Raspberries need support to grow properly and these supports assist in maintaining narrow rows of raspberry plants. Create a trellis before or soon after planting your raspberries and control the suckers that appear to form the rows. Keeping raspberries in narrow rows along a four-wire "T" trellis provides a good growing environment for the plants.
Use a hole digger to make holes 2 feet deep at the end of each row of raspberries. Space the post no more than 30 feet apart. Raspberries typically are planted every 2 feet along the row.
Place a 6-foot fence post in each hole. Use a shovel to add dirt to the hole to secure the post in place. Compact the soil around the post.
Hammer a cross arm to each post 3 feet above the ground to create a "T" trellis. Use rope and a stake to anchor each end post in place.
Attach heavy gauge wire to each side of the cross arm. Run the wire across the row of raspberry plants to the other post and attach it to the cross arm.
Place two additional wires on each side of the end posts 30 inches above the ground. Run the wires to the other end of the row and attach at same height to post.
Use the two bottom wires to maintain the raspberries in a narrow row between the wires. Train the raspberry plants to grow up and attach them to the top wires with twine when tall enough.
Remove any suckers that appear 6 to 9-inches from the center of the row. Maintain rows 1 to 1 1/2 feet wide at the base.
Use a rake outside of the rows to cultivate the soil to remove any weeds or suckers in the area. Do not cultivate more than a few inches into the soil.
