How to Sink a Trellis


Gardeners take advantage of every inch of soil they have by growing plants horizontally and vertically. According to Jane Courtier, author of "Great Ideas for Your Garden," a trellis hides unpleasant views. Many plants require some sort of support to grow upward. Climbing roses require a heavier support than lighter vines like clematis. A trellis can be the ideal support for most vines.

Against a Wall or Fence

Step 1

Dig a hole for the trellis that is 18 inches deep and 12 inches in diameter. Position the hole so the back of it is 12 inches away from a wall or fence. Place the bottom end of the trellis in the hole and lean the top of the trellis against the wall or fence.

Step 2

Fill the hole with 6 inches of gravel. Make sure there is gravel in back and all around the bottom of the trellis.

Step 3

Mix the cement with water in a bucket according to package directions. Pour the cement over the gravel. Push it into the gravel using the hand shovel. Check to make sure the trellis is straight but still leaning back on the wall or fence.

Free Standing

Step 1

Dig the hole 18 inches deep and 12 inches wide.

Step 2

Nail two 6 inch wooden bars horizontally to a 12 inch long wooden bar. The exact width of the wooden bars isn't that important. You can use scrap wood.

Step 3

Nail the double crossed extension bar to the end of the trellis. Most trellises don't have enough length at the bottom to secure them firmly in the ground. The extension does that.

Step 4

Place the trellis in the hole. Fill the hole with 4 inches of gravel.

Step 5

Mix the cement. Pour the cement into the hole so it comes to the top of the gravel. Add another 4 inches of gravel and top with cement. Continue alternating gravel and cement until the hole is filled to within 4 inches of the top.

Tips and Warnings

  • Wear gloves when handling cement. It irritates the skin.
