DIY Pallet Planter Box

Planter boxes are the perfect vessels for cascading flowers. They look awesome hanging off a deck or near a window outside the house. You can easily make one out of leftover pallet wood like Amy from Her Tool Belt did. Her tutorial includes helpful step by step instructions and photos.


Here are the materials you’ll need:

  • 2” x 4” x 40” (4) – for the legs
  • 2” x 2” x 15” (2) – for bottom support
  • 1” x 4” x 36” (4) – bottom
  • 1” x 1 ½” x 36” (1) – bottom
  • 40” long pullet slats (as needed)
  • 16” long pullet slats (as needed)
  • 2” hole saw
  • drill
  • 1 ¼” screws (as needed)
  • 2 ½” screws (as needed)

Note: If you don’t have enough pallets, you can substitute with cedar pickets or pine 1 x 4’s found in hardware stores.


The first thing you need to do is disassemble the pallet. Check out this video for the easiest way to disassemble a pallet while leaving the nail holes intact.

Assembly of the planter is fairly straightforward and easy. After attaching the wood parts together with screws, fill any gaps with scrap wood or weed guard.

Next, you’ll need to drill holes for the flowers using a 2” hole saw. Make 3 rows of holes spaced 6” apart.


The most fun part is planting the flowers. You can choose from a number of cascading flowers like begonias, geraniums, lobelias, petunias, or million bells. Put in a layer of good potting mix and moist soil to help retain water. Since the box is fairly large, you’re going to need a lot of soil. About 2 bags should do for the entire planter.

Add a row of flowers, then cover with soil. Repeat this process until you get three layers of flowers. Finish the top off by planting a final layer of flowers.


Make sure to water the flowers every day. Water until you see the water leaking from the lower holes. Add fertilizer once a week. Spray with organic bug spray at least once a week to eliminate bugs that sometimes prevent flowers from growing.

Enjoy your flowers as they bloom and grow.
