## Step 1: Selecting Lumber and Getting Tools

Purchase a bundle of lumber. I choose to buy 48"x1.5"x0.25"pine due to the low cost. Select 32 pieces that are straight and lay flat. I used a small diameter drill bit for predrilling holes, and 0.5" length screws #2 diameter for fastening the wood.

## Step 2: Forming the Criss-Cross Pattern

Using a square, or a block of wood with square sides, align the ends of two pieces of wood and fasten them together orthogonal one to the other. Then, moving down the piece of wood on the bottom with gap spacing of 3.5" between the pieces of wood, attach 9 pieces of wood so that there are 9 total. You will need to align one side of your trellis against a wall or something straight to keep the wood pieces at the correct angles.

Note, my block of wood had a width of 3.5".

## Step 3: Flipping Over the Trellis and Attaching Complementary Pieces

Grab hold of the main piece of wood that has 9 other pieces attached to it. Carefully turn over your trellis. If some of the pieces rotate you will need to adjust them back to the correct right angles. Attach the 8 pieces of wood needed so that both sides of the trellis have 9 complementary pieces. Keep the gapping at 3.5". You will know if you are doing this correctly if you are producing 3.5" square shapes in the trellis design.

## Step 4: Filling in the Gaps on the Ends

To make you trellis long enough you need to add 3 pieces of wood to each end. Then you will need to flip over the trellis and add 3 pieces of wood to each end. That is a total of 12 pieces of wood. As you are attaching the wood mark the existing corners of the trellis so that you know where to chop the wood to make a straight side. This is also a good time to add strength to the main body of the trellis by inserting additional screws in the middle.

## Step 5: Filling Out the Corners and Adding Support Stakes

The original corners of the trellis that were marked in the previous step form a line where a cut should be made on each of the 3 pieces of wood used to fill in the gaps. As a cuts are made squaring up the sides there should be a total of 6 pieces of wood chopped on each side. Save these additional pieces for use in filling the corners in. They should be just the right size due to the mathematical nature squares and lengths of sides of squares. Fill in the corners then add a piece of wood on each side of the trellis. These 2 pieces of wood will extend bellow the trellis and can be buried in the ground so that the trellis stands vertically above the ground.

Very nice to have a DIY idea for trellis. Is it necessary that the pieces should be diagonal to the border pieces or straight grid like graph paper lines can also be made?

how much did this set you back in total?

I remember the lumber costing 5 dollars and the screws cost 2 dollars, all this was purchased at The Home Depot.

I got sticker shock last year when I was at the big orange box store looking at pre-assembled trellises they had. Yours seems much more reasonably priced to me. I need to make something for my beans this year.

How should the wood be protected from fungus or any other infection?

I had planned for the wood to weather and deteriorate, but anyone who wants to preserve their trellis can do so by painting or staining the wood.

Thanks. You have shown a very nice method for making a trellis.
