Cinder blocks, often considered a humble building material, can be transformed into stylish and functional corner planters. These concrete blocks are not only durable and affordable but also offer a unique rustic charm that can elevate your outdoor space. In this article, we'll explore creative cinder block corner planter ideas that are easy to build and maintain, perfect for both beginners and experienced DIY enthusiasts.

Why Cinder Blocks for Corner Planters?

Cinder blocks are an excellent choice for corner planters due to several reasons:
- They are inexpensive and widely available.
- Cinder blocks have a hollow core that makes them lightweight and easy to handle.
- They provide excellent drainage, which is crucial for healthy plant growth.
- Cinder blocks can be easily stacked and secured to create sturdy structures.
- With a bit of creativity, cinder blocks can be transformed into visually appealing planters.

Cinder Block Corner Planter Ideas
1. The Classic Stacked Planter

The simplest way to create a cinder block corner planter is by stacking them in a corner. You can create a simple, low-level planter by stacking two or three blocks on top of each other. For a more substantial structure, stack them up to five or six blocks high. Secure the blocks together using mortar or construction adhesive to prevent them from toppling over.
2. The Built-In Bench Planter
Create a functional and attractive corner planter by building a bench using cinder blocks. Stack the blocks to create a seat and backrest, then add a wooden plank for comfort. Surround the bench with plants to create a cozy outdoor seating area. You can also add a table made from a wooden pallet or a concrete slab for a complete outdoor setup.

3. The Tiered Planter
Tiered planters allow you to grow a variety of plants at different heights, creating a lush, vertical garden. To create a tiered cinder block planter, stack the blocks in a pyramid shape, securing them together as you go. Place the largest blocks at the bottom and gradually decrease the size as you move upwards. Add wooden planks or metal trays between the tiers to create planting spaces.
4. The Mosaic Planter

Give your cinder block planter a unique touch by creating a mosaic design on the outside. Use broken tiles, glass, or pebbles to create a colorful, eye-catching pattern. Apply a thin layer of mortar to the block, then press the mosaic pieces into the wet mortar. Allow the mortar to dry completely before planting.
5. The Hanging Planter


















Create a hanging cinder block planter by drilling holes in the sides of the blocks and inserting metal or plastic chains. Hang the planter from a sturdy structure, such as a wooden beam or a metal frame. This type of planter is perfect for growing trailing plants, such as ivy or petunias, and can be used to create a living wall or screen.
6. The Raised Bed Planter
Build a raised bed planter using cinder blocks to create a deep, spacious planting area. Stack the blocks to the desired height, then secure them together using mortar or construction adhesive. Line the inside of the planter with a waterproof membrane to prevent moisture from seeping into the blocks. Fill the planter with high-quality soil and plant your favorite vegetables, herbs, or flowers.
Caring for Your Cinder Block Corner Planter
Cinder block planters are low-maintenance, but they do require some care to keep them looking their best:
- Water your plants regularly, especially during hot, dry weather.
- Add a layer of mulch to the top of the soil to help retain moisture and suppress weeds.
- Prune plants as needed to encourage bushy growth and prevent them from becoming too leggy.
- Inspect your planter for signs of damage, such as cracks or crumbling, and repair as necessary.
- Clean your planter annually to remove any dirt or debris that has accumulated on the outside.
With a little creativity and some basic DIY skills, you can transform ordinary cinder blocks into stunning corner planters that will enhance your outdoor space. Whether you prefer a simple, rustic look or a more elaborate, decorative design, there's a cinder block corner planter idea that's perfect for you.
