How to Design a Lattice Trellis

A lattice trellis is one of the simplest trellis designs. The classic grid-like pattern and simplicity are perfect as a support structure for ornamental climbing plants. They are remarkably easy to build and allow for personalization of style through the use of different materials.

Things You'll Need

• 2 support posts, each 2 by 2 or 4 by 4
• Wood strips (size and number varies by style)
• Hammer
• Galvanized nails
• Metal braces
• Wood saw

Instructions

1. Determine the size of the lattice trellis you want to build. Factors to consider include location in the yard and what kind of plant (if any) will be growing on it. A top-heavy plant will need a sturdier lattice design and therefore require more substantial wood materials.

2. Calculate the length and number of wooden strips you'll need. This calculation is simple, as most lattice designs are simple grids. This means that if you choose 2-inch wide wood strips for your lattice, you'll evenly space each strip 2 inches apart. Simply take the length of your frame and divide by 2 to determine the number, and do the same for the width of the frame. The length of your strips will correspond to the measurements for the length and width of the frame.

3. Assemble the frame. Unless the trellis will be supporting heavier plants or other items such as hanging baskets, you can simply lay out your posts and nail them together at the ends. If you want a sturdier trellis, consider using a metal brace at each joint for added stability.

4. Attach the latticework. Start at the ends and nail the wood strips to the frame. Measure in order to space them evenly. When you are done with the strips in one direction, go back and repeat the same steps in the opposite direction to form your grid.

5. Treat or paint your lattice trellis according to your own style. If you like the look of natural wood, it is still advisable to treat with a clear stain or polyurethane coating for weatherproofing.

6. Mount the trellis in the yard. If you want the structure to be free standing, be sure to leave extra length on the vertical posts in order to set them in the ground deep enough for stability. If mounting against the house, secure the top of the trellis to the wall using wire or a brace. These can be easily obtained at a local hardware store.
