Fill tall planters cheaply

Warm weather makes me want to work outside, so we’re spending the next few weekends working in the yard. Over the weekend, I did the most simple project ever. I love the look of tall planters flanking the entry to the doorway, so I bought some.

But once I got them home, I realized that I had no clue how to fill them. I could use a million bags of dirt, but they would be so heavy! I’ve seen where people fill them with packing peanuts, and that’s great if you have them around, but we don’t.

What we do have is tons of scrap wood though! So an idea was born.

You will love this idea if you are wondering how to fill tall planters. Plus, if you have a bit of a black thumb, like I do, you can easily switch out plants when they die!

Reasons to Fill Tall Planters with Things Other than Dirt

  • Weight. A tall planter full of dirt is going to be so heavy. If you want to move your planter for any reason, it’s going to be hard to do so!
  • Cost. Potting soil costs money, but most of my suggestions are things that you have laying around the house, so they’re free. 
  • Drainage. Filling the bottom of the container with items other than dirt helps with drainage so that your plant is not sitting in a mud pit during the rainy season.

Supplies Needed


  1. Figure out your measurements. Measure your tall planter and your plant pot. Subtract the plant pot amount from the tall planter. Our planter was 21″ tall and our plant pot measured 7″ so we needed to fill 14″ of space. Wood, planter and fern
  2. Cut your scrap wood to that length. We used scrap 6×6 pieces and it filled the pot nicely while also giving weight to the base. If you’re using smaller pieces, screw them together. Make sure they fit in your pot!Place wood in planter
  3. Drill drainage holes in your pot if you don’t have them already. We have a mosquito problem in the summer, so we try to cut down on any areas where water can stand. Drill holes in bottom of planter.
  4. Place wood in pot.
  5. Add gravel in the bottom to add weight. We’ve found that these planters are top heavy and will fall over, so adding the gravel to the bottom helps.
  6. Place plant on top. So easy! Now if it dies, you can just replace it with another cheap plant!Tall planter on porch

I love how the ferns look in the simple black pots! And best of all, they are so easy to move around!

    • I didn’t have any planters that were tall enough or I would done that. After I bought these, I found (super expensive) ones that have removable pots in the top for planting in. My way is almost as good. đŸ˜‰

  1. I love those planters too! I couldn’t tell they were plastic until you turned them over. Beautiful and simple!
