Overview

Blackberries are an easy fruit to grow in your garden. A properly maintained blackberry patch will produce berries for up to 20 years. To assure your blackberry patch remains healthy and productive, build a trellis on which to train the canes. Your plants will be healthier and it will be much easier to pick the berries.

Step 1

Use the post hole digger to dig a hole at each end of the row of blackberries. Make the hole 24 to 36 inches deep.

Step 2

Set the 6-inch by 6-inch post into the prepared hole.

Step 3

Mix the quick set concrete following the manufacturer's directions.

Step 4

Pour the concrete into the post hole. Overfill the hole slightly.

Step 5

Use the cement trowel to slope the concrete away from the post above the surface of the soil. This will allow rainwater to drain away from the post.

Step 6

Lay a carpenter's level vertically alongside the post and adjust the post so that it is "plumb"--that is, vertically straight up and down.

Step 7

Allow the concrete to set and cure for 24 to 48 hours.

Step 8

Drill one starter hole 3 feet above the ground and another starter hole 5 feet above the ground. Place the starter holes in the center of the post at their appropriate heights. Attach metal loops or "eyes" to the posts for attaching the wires.

Step 9

Fasten heavy gauge wire between the corresponding metal loops or "eyes," connecting the post with the wire strung along the row of blackberries.

Step 10

Train primocanes--canes formed the current year--to trail along the ground. Train floricanes--canes formed the previous year and the ones which will bear fruit this year--by tying them first to the lower wire and then tying and training them to grow along the upper wire.
