Instructions

STENCILING THE CINDERBLOCKS:

Note: We chose to stencil the front of 12 cinderblocks and the end of 2 cinderblocks. The remaining cinderblocks were left plain. It is up to you how many cinderblocks you wish to stencil.

  1. Put on an apron. Use a large paintbrush or foam roller to paint all sides of all the cinderblocks with exterior latex paint and primer using the base color of your choice. Painting all the sides is preferable but it is not necessary to paint the bottom of the cinderblocks. Any base paint drip marks won’t be seen on the bottom of the cinderblocks once the planter is assembled. Allow the paint to dry for 2-4 hours or until dry to the touch before moving onto the next step
  1. Pour the two stencil paint colors into two paint trays. Use the different paint colors for different stencils however you choose. Lay a cinderblock on its side and lay a stencil of your choice on top of it. It doesn’t need to cover the whole cinderblock – it’s up to you how you want it to look. If the stencil covers the whole of the cinderblock, use a regular paint roller to apply paint over the stencil. If the stencil only covers part of the cinderblock, use the tip of a roller to dab the paint over the stencil. Carefully remove stencil and set the cinderblock to one side to dry (See images below)

Expert Tip: Make sure to remove as much excess paint as possible from the rollers so the paint doesn’t bleed under the stencil. You can also use painter’s tape to hold the stencil in place if you find it’s lifting too much when you paint over it.

  1. Three of the cinderblocks will have one end visible in the final configuration of the cinderblock planter. Add stencils to the ends of up to three cinderblocks for use in later steps (See image below)

  1. Allow all the stenciled cinderblocks to dry for 2-4 hours before moving on to the next step

BUILDING THE CINDERBLOCK PLANTER:

Note: The cinderblocks will be built up in five separate layers. No mortar is needed between the blocks, as their collective weight will hold them in place. Heavy-duty construction adhesive will only be used to help hold the three protruding cinderblocks on Layers 2 and 3. Layer 1 is the foundation layer and should be placed against an existing wall for additional support. The configuration listed here will be 8’8” long.

  1. For Layer 1 you will need (6) double cinderblocks and (1) single cinderblock. It is up to you where you want to place the stenciled cinderblocks in the configuration. Follow the diagram below for placement of blocks on Layer 1, starting from left to right

Expert Tip: Be sure to lift with your legs, not your back, when carrying cinderblocks.

  1. Each layer is color-coded. Use the previous layer as a guideline for placing the next layer. For Layer 2 you will need (6) double cinderblocks and (1) single cinderblock. Follow the diagram below for Layer 2 placement of blocks on top of Layer 1 starting from left to right. When you get to the two protruding cinderblocks, apply a line of heavy-duty construction adhesive to the top of the cinderblock below, and then place the protruding cinderblock on top. If needed, place a cinderblock from Layer 3 directly on top to help keep it in place

Expert Tip: Use a rubber mallet to tap into place any blocks that need a slight adjustment.

  1. For Layer 3 you will need (5) double cinderblocks. Follow the diagram below for Layer 3 placement of blocks on top of Layer 2

  1. For Layer 4 you will need (2) double cinderblocks and (1) single cinderblock. Follow the diagram below for Layer 4 placement of blocks on top of Layer 3

  1. For Layer 5 you will need (1) double cinderblock. Follow the diagram below for Layer 5 placement of block on top of Layer 4

ADDING THE PLANTS:

  1. Chicken wire baskets with plastic liners are needed in each cinderblock hole so the plants won’t fall through. Each cinderblock hole is approximately 4” x 4” x 6” which will be the dimensions of the finished chicken wire baskets. Put on work gloves. To make a chicken wire basket, cut (2) 4” x 16” strips of chicken wire using wire snips. Using the 1” x 4” scrap lumber to help, bend each piece of chicken wire into a U-shape (See images below)

  1. Place one U-shape inside the other to make the four sides of the basket. Carefully bend the ends of the chicken wire together to maintain the basket shape (See images below)

  1. Place a 14” x 14” plastic liner inside the chicken wire basket. Use an icepick to poke 5-6 holes in the bottom of the liner for drainage (See images below)

  1. Repeat Steps 10 to 12 to make an additional 15 baskets, one for each hole in the cinderblock planter. Once all the baskets are made, place them in the cinderblock holes (See image below)

  1. Remove the succulents and other plants one at a time from their plastic pots and plant them in the baskets. Add potting soil around the plants if needed. Cover any gaps between the plants and the sides of the cinderblock holes with decorative moss (See images below)
