Growing Raspberries: How To Build A Trellis Growing Raspberries: How To Build A Trellis

Growing raspberries isn't difficult once the plants are established. Raspberries can grow so easily. Canes will often bend over like this and root to the ground or be damaged because of their height, weight and fullness. A raspberry trellis is an easily solution to this problem.

Tools Needed:

•2 posts about 6' long
•2 posts about 42" long
•Wire
•Clam shell  shovel
•Phillips screwdriver
•Power drill
•Screws
•Measuring tape

Step 1 – Measure and Mark


Measure the length of the row you want for growing raspberries. Your row will need to be about 1 to 1 ½ feet wide. Raspberry plants need to be spaced between 2 and 3 feet apart, so figure how many plants you have and how long your row will be, then measure that out and mark the ends so you'll know where to put your posts so you can build a trellis that's the right size. A good length for a row is about 20 feet. If you have more than 10 plants then you'll want to make two rows and build a trellis for each row separately. If the row is longer, the wire used has more chance of hanging lower than you intend, especially near the middle.

Step 2 – Place End Posts

Once the spots are marked, then use a clam shell shovel to dig a hole at each marked end. The hole should be about 2 feet deep for best results. A hole that's not as deep won't offer the right amount of support for the trellis or the raspberry plants. Then take the 2- 6' posts and place in each hole. This will leave about 4' of wooden post standing out of the ground. Press the dirt securely around each post to keep them stable.

Step 3 – Attach the Smaller Posts


Take the 2-42" posts and attach one to the top of each end post using the power drill and screws so that you form a "T" with each end post. You can attach them a foot from the top of each end post or on the very top. The wire will run from end to end, attached to these posts, so place them at the height you want the wires to run.

Step 4 – Drill Wire Holes


Drill a hole in each end of the 42" posts, about an inch from the end. These are the holes where the trellis wire will be attached.

Step 5 – Attach the Wire

Measure two piece of wire 4 feet longer than your raspberry row. Run each piece between the two matching holes you just drilled so that each one runs the length of the row. Center it so that the extra wire makes up 2 feet on each end. Wrap that wire around the post to keep it securely in place. Now, your growing raspberries will be supported by the wire of your new raspberry trellis and avoid touching the ground.
