Before we dive into the how-to, let’s explore the advantages of using cinder blocks for your wall planters:

Affordability: Cinder blocks are significantly cheaper than many other planter materials, making them a budget-friendly choice.
Durability: These blocks are incredibly durable and can withstand harsh weather conditions, ensuring your planter will last for years to come.
Versatility: Cinder blocks can be arranged in countless configurations, allowing you to create a planter that perfectly fits your space and style.
Customization: They can be easily painted, stained, or decorated to match your outdoor décor.
Modular Design: The modular nature of cinder blocks makes it easy to add or remove sections as needed, allowing you to adapt your planter to changing needs.
Space-Saving: Wall planters are an excellent solution for small spaces, allowing you to maximize your planting area without taking up valuable ground space.
Easy to Build: Constructing a cinder block wall planter is a relatively simple DIY project that requires minimal tools and experience.

Materials You’ll Need

Here’s a list of the essential materials you’ll need to create your cinder block wall planter:

Cinder Blocks: The quantity will depend on the size and design of your planter. 12-inch cinder blocks are a good starting point, but you can adjust the size as needed. Consider the weight of the blocks and the stability of the underlying surface.
Extra Blocks or Pavers: These will be used to create a bottom inside the cinder blocks, providing a more suitable planting depth and preventing soil from leaking out. Broken pieces of terracotta pots can also be used as an alternative for drainage.
Construction Adhesive (e.g., Liquid Nails): This will be used to securely attach the extra blocks or pavers to the inside of the cinder blocks. Ensure the adhesive is suitable for outdoor use and can bond to concrete.
Paint (Optional): If you want to customize the look of your cinder blocks, choose an exterior-grade paint that is resistant to fading and weathering. Consider using primer for better adhesion.
Gloves: Protect your hands from the rough surface of the cinder blocks and the adhesive.
Safety Glasses: Protect your eyes from dust and debris.
Level: Ensure your planter is level and stable.
Shovel or Trowel: For adding soil to the planters.
Soil: Choose a potting mix suitable for the plants you intend to grow.
Plants: Select plants that thrive in your local climate and the amount of sunlight your planter will receive.

Step-by-Step Instructions

Follow these steps to build your own cinder block wall planter:

Plan Your Design: Before you start building, sketch out your desired planter design. Consider the size, shape, and height of your planter, as well as the number of plants you want to include. Think about the overall aesthetic you want to achieve and how the planter will complement your existing outdoor décor.
Prepare the Surface: Choose a flat, stable surface for your planter. If you’re placing it on grass or soil, consider laying down a layer of gravel or pavers to provide a solid foundation and prevent the blocks from sinking.
Arrange the Cinder Blocks: Arrange the cinder blocks according to your planned design. Experiment with different configurations to find the layout you like best. Consider staggering the blocks to create a more visually appealing and structurally sound planter.
Create the Bottom: Attach the extra blocks or pavers to the inside bottom of each cinder block using construction adhesive. This will create a solid bottom for your planter and prevent soil from leaking out. Apply a generous amount of adhesive to the bottom of the paver or block and press it firmly into place inside the cinder block. Allow the adhesive to dry completely according to the manufacturer’s instructions. Consider adding drainage holes in the bottom blocks if necessary.
Paint (Optional): If you’re painting your cinder blocks, now is the time to do it. Apply a primer first for better adhesion and then apply two coats of your chosen paint color. Allow the paint to dry completely before proceeding.
Add Soil: Fill each cinder block cavity with potting mix. Leave a few inches of space at the top for watering.
Plant Your Plants: Carefully plant your chosen plants in the soil. Be sure to follow the planting instructions for each plant.
Water Thoroughly: Water your plants thoroughly after planting.
Maintain Your Planter: Regularly water, fertilize, and prune your plants as needed. Keep an eye out for pests and diseases and take appropriate action.

Design Ideas and Inspiration

Here are some creative design ideas to inspire your cinder block wall planter project:

Vertical Herb Garden: Create a vertical herb garden by stacking cinder blocks and planting different herbs in each cavity. This is a great way to add fresh herbs to your kitchen while saving space.
Succulent Wall: Succulents are drought-tolerant and low-maintenance, making them ideal for cinder block planters. Create a stunning succulent wall by planting a variety of different succulents in each cavity.
Colorful Flower Display: Add a pop of color to your outdoor space by planting vibrant flowers in your cinder block planter. Choose flowers that bloom at different times of the year to ensure a continuous display of color.
Tiered Planter: Create a tiered planter by stacking cinder blocks in a stepped formation. This will add visual interest and allow you to plant different types of plants at different heights.
Painted Designs: Get creative with paint and add unique designs to your cinder blocks. You can paint geometric patterns, floral motifs, or even create a mural.
Add Lighting: Incorporate string lights or solar lights into your cinder block planter to create a warm and inviting ambiance.
Combine with Other Materials: Mix cinder blocks with other materials, such as wood or metal, to create a more unique and interesting planter.

Climate: Select plants that are well-suited to your local climate.
Soil Drainage: Ensure your soil drains well to prevent root rot.
