When windows aren’t the right size or too complicated for window boxes, there’s another gorgeous option: A simple planter box for underneath.

This simple planter box is gorgeous and easy to make. It takes just a bit of time and can be used for flowers, herbs or even a vegetable garden.

I thought window boxes would make a great Mother’s Day gift for my mom. Alas, attaching big window boxes to her large windows was a little more difficult of a project than I wanted to tackle.

Underneath her window sits decorative rock just begging for some spring life. I still wanted to build window boxes but knew I’d need to adapt the dream to her situation. I’d also need some help from my husband! He stepped in to help make a simple window box that would make her windows pop.

Every time we arrive at her house, we are greeted by beautiful welcoming flowers under the front windows. These simple planter boxes are beautiful.

This doesn’t take a lot of supplies or time to make. Here’s how to make a simple planter box.

You’ll need:

One 2″ x 6″ X 10′ piece of cedar or pressure treated board
Pressure treated piece of plywood for bottom ( at least 1′-3″ x 4′)
Eight 3″ long outdoor wood screws
Twenty 1.5″ long outdoor wood screws ( screw needs to be at least an inch longer than the thickness of bottom wood)
Flowers to fill box
One bag ( 2 cu. ft. size) of potting soil to fill box.

Tools you’ll Need:

Skill saw
Drill and driver bit to fit screws
1/4 inch drill bit
A square layout tool

Directions:

  • Cut two 1′ pieces from 2″ x 6″ x 10′ board. Cut two 4′ pieces from rest of 2″ x 6″ x 10′ board. Place 1′ boards between the 4′ boards so ends are even. This should create a rectangle with dimensions of 1′-3″ X 4′.
Screwing the Planter Boards together
  • Use a square to square corners. Screw two of the 3″ wood screws through 4′ board into 1 ft. board at each corner. Screws should be about 1.5 inches from the top and 1.5 inches from the bottom.
  • Trace rectangle of box onto plywood. Cut out the bottom of the plywood piece from tracing.
  1. Place bottom piece of plywood on top of the upside down box. Line up the edges. Use 1.5 inch wood screws to secure the plywood to the planter box by evenly distributing the screws along outer edges.
  1. Use 1/4 inch drill bit to drill approximately 24 holes throughout bottom of plywood for water drainage.
  1. Put box in desired place (Under a window is perfect) and fill with potting soil. Plant flowers or other plants and water well.
Yield: One 1' x 4' Planter Box
