How to Make DIY String Light Poles for a Brighter Outdoor Space

How to Build Temporary DIY String Light Poles

1. Buy Planters

   Look for a planter that holds around 5 gallons of concrete with a thick bottom that you can screw L-brackets to hold the post until the concrete hardens.

   Plus, a thicker wood or plastic bottom will ensure the material doesn't crack beneath the weight of the concrete, especially during relocation.
   

   Tip

   Choosing larger planters and partially filling them with concrete will leave room at the top for potting soil and plants.

   Mount the Posts to the Planters

   Secure the post to the planters following these steps:

   • Place the post centered in the planters.
   • Secure it to the bottom using L-brackets and screws.
   • Place the planter on level ground and check that the post is plumb using a level.
   • Adjust if necessary.

2. Mix Concrete

   Follow the manufacturer's instructions to mix your concrete in a five-gallon bucket.

   Regarding the amount of concrete you need, follow these guidelines:

   • If you're putting plants and soil on top of the planters, leave a few inches of room.
   • If you're filling the planter concrete, mix enough concrete to reach the top, then slightly round off the surface so it sheds water.

3. Pour Concrete into Planters

   To fill the planters, follow these steps:

   • After checking to ensure the post is still plumb, carefully pour the concrete into the planters.
   • Tap the sides of the planter with a hammer to get any air bubbles out of the concrete and level the surface.
   • Smooth the surface with a trowel or similar tool.

4. Drill Drainage Holes (Optional)

   If you left room for plants above your concrete, drill four equidistant drain holes just above the top of the concrete.

   Tip

   Adding a layer of rock beneath your soil will encourage better soil drainage, which is crucial for many plant species.

5. Mount Hardware

   At the top of the string light poles, attach your hardware of choice. Stainless-steel hooks will hold the sting lights securely without failing due to weather exposure.

How to Build DIY Permanent String Light Poles

To build permanent string light poles, forgo the planters and put your posts in the ground following these steps:

1. Dig and Measure. Dig a hole measuring 8 to 10 inches with a depth of 1/3 of the length of your posts.
2. Attach Support Legs. Place a ground-contact post in the hole and attach scrap board support legs to hold it plumb until the concrete sets.
3. Fill With Concrete and Dirt. Fill the bottom half of the hole with concrete, then fill the rest with the dirt you removed.
4. Attach Hardware. Once the concrete sets, remove the scrap board support legs and attach your hardware at the top of the pole.
