How to make a wood support for climbing plant

Wood support for climbing garden plants

A few years ago we planted a climbing plant in the garden, specifically a beautiful wisteria. Fortunately this climbing plant does not grow too fast, and it is easy to control by pruning it regularly. The thing is that my parents thought it was a good idea to guide a part of it halfway up in front of the porch of the house, and for this they improvised a support with some metal pipes.

Needless to say that an improvised climbing plant support made of metal pipes does not usually look very nice in the garden. So, as you can see by the size of the climbing plant, I have been waiting for some time to make, with some treated wood posts, a nice support for this climbing plant.

How to make a climbing plant support with wood posts

To make this kind of garden support I used some treated wood posts, one of those typical ones you can find for sale in DIY centers, in farms and garden centers. The thicker posts are easy to find, but to find the thinner ones I had to go to several stores.

Level the wood post on the drill press table

In theory joining the parts of the garden support is very simple. I just have to drill a few holes in the thicker vertical posts, with enough diameter to allow the thinner horizontal posts to pass through. But we will see it is not so simple is to drill the holes in the wooden posts to make the climbing plant support. The first thing I had to do is set up a stand at the same height as the drill press table to keep the wood posts level while drilling them.

The next problem was to keep the wooden posts from rolling while I drill them, but a few spring clamps to each side was enough to hold them in place. I mark the distance to witch I want to drill the holes from the head of the post, and I start drilling the holes in the posts with the hole saw drill press bit.

As the hole saw drill bit does not allow a hole to be drilled all the way through to the other side of the thick posts, I took advantage of the center hole it leaves and I use a normal wood drill bit to make a drill through that centering hole to the other side of the post. This way, now I can turn the post and fit the centering bit of the hole saw in the drill I made and finish drilling the hole completely through the post.

Align the holes in the post by eye

The order I followed to make the holes was to use the hole saw to drill the holes on one side of all the posts first, then I used the normal wood drill bit to make all the centering drills side to side of the posts, and then again I used the hole saw to finish making all the holes. Carefully I align by eye the hole that has to be made in the middle of the posts with the first hole that was made near the top end of the posts. If they are not aligned well they will give problems when fitting the horizontal posts to make this climbing plant support.

Driving wood fence posts by hand

Finally, I applied a protective stain for wood to all the wooden posts. It will improve the protection they already have, as they are treated wood, and will also homogenize the color. And with the sledgehammer and the help of the meter and a level, I drive the fence posts by hand in its place in the garden. I thought this part of making a climbing plant support would be the easiest part.

But since drilling the posts weakens them, the top of two posts cracked and a piece separated when I hit with the sledgehammer to drive them into the ground. Well, I had to put a vertical wooden block at the base of the hole to finish driving them by hand with the sledgehammer.

Glue the broken head of the post

After assembling the horizontal posts I used special glue for exteriors and glued the broken parts. I held them tight for one day with the cheap woodworking clamps. And now, once the glue is dry, the final appearance of this wooden support with the climbing plant on it is really nice.
