Creating your own concrete Spherical Planter using a yoga ball is a creative way to add a modern, stylish touch to your garden or patio. This comprehensive guide will walk you through the entire process, from gathering materials to finishing your planter, ensuring you achieve professional-looking results. Let’s get started!
Materials You Will Need
Before diving into the process, ensure you have all the necessary materials on hand:
- Yoga Ball (16-24 inches): The ball size determines the final size of your planter.
- High-Strength Concrete Mix: Opt for a mix that is durable and suitable for outdoor use.
- Adhesive Mesh Tape: This tape helps reinforce the concrete, providing extra strength.
- Plastic Wrap: To prevent the concrete from adhering to the yoga ball.
- Bucket or Large Mixing Container: For mixing the concrete.
- Water: To mix with the concrete.
- Trowel or Spatula: For applying and smoothing the concrete.
- Safety Gear: Gloves, mask, and safety glasses to protect your skin, lungs, and eyes during the process.
- Sandpaper or File: For smoothing out rough edges once the concrete has cured.
- Drill with Masonry Bit: To create drainage holes if necessary.

Step 1: Prepare a Spherical Planter with a Yoga Ball
- Inflate the Yoga Ball
Inflate the yoga ball to your desired size, keeping in mind that this will be the diameter of your finished planter. - Wrap the Ball with Plastic Wrap
Cover the entire surface of the ball with plastic wrap. This step is crucial as it prevents the concrete from sticking to the ball, making it easier to remove once the concrete has set. - Secure the Ball on a Stable Surface
Place the yoga ball on a flat, stable surface, such as a large bowl or container, to prevent it from rolling while you work on it.
Step 2: Mix the Concrete
- Prepare the Concrete Mix
Follow the manufacturer’s instructions on the concrete mix packaging. Typically, you’ll need to mix the dry concrete with water in a bucket or large container. Aim for a thick, peanut-butter-like consistency that will hold its shape when applied. - Mix Thoroughly
Stir the concrete mixture thoroughly to ensure an even consistency. Make sure there are no dry pockets or lumps, as these can weaken the final structure of your planter. - Let the Mix Rest
Allow the concrete mix to sit for a few minutes to settle and reach the perfect consistency for application.
Step 3: Apply the Concrete
- Cut and Apply Adhesive Mesh Tape
Cut strips of adhesive mesh tape and apply them to the surface of the yoga ball in a grid pattern. This tape provides structural reinforcement for the concrete, reducing the risk of cracking. - Apply the First Layer of Concrete
Using a trowel or spatula, apply a thin layer of concrete over the mesh tape. Start from the top and work your way down, ensuring an even coat. - Build Up the Concrete Layers
Once the first layer is applied, gradually add more concrete, building up the thickness to at least 1 inch. This will give your planter the necessary strength to hold soil and plants. - Smooth the Surface
After applying the final layer, smooth the surface with your trowel or spatula. Don’t worry if it’s not perfect; a slightly rough texture adds to the rustic appeal of the planter.
Step 4: Let the Concrete Cure
- Allow the Concrete to Set
Let the concrete cure for 24-48 hours. The curing time may vary depending on the concrete mix and environmental conditions. Ensure the concrete is completely dry and firm before proceeding. - Monitor the Curing Process
Check the planter periodically during the curing process to ensure it is set evenly. If you notice any cracks or uneven areas, you may need to apply more concrete or smooth the surface again. - Deflate and Remove the Yoga Ball
Once the concrete has fully cured, carefully deflate the yoga ball. The ball should easily detach from the inside of the concrete sphere, leaving you with a hollow planter.
Step 5: Finishing Touches
- Smooth Rough Edges
Use sandpaper or a file to smooth out any rough or sharp edges on the planter. This will give it a polished, finished look and make it safer to handle. - Drill Drainage Holes
If you plan to plant directly in the sphere, drill a few drainage holes at the bottom using a drill with a masonry bit. This will prevent water from accumulating inside the planter, protecting your plants’ roots from rot. - Seal the Concrete (Optional)
For added durability, especially if your planter will be exposed to the elements, consider applying a concrete sealant. This will protect the surface from moisture and extend the life of your planter. - Decorate Your Planter
You can leave the planter as is for a natural, industrial look, or you can paint it to match your garden’s aesthetic. Consider using weather-resistant paint for outdoor durability.
Common Questions & Troubleshooting for Spherical Planter
Q: Can I use a different type of ball instead of a yoga ball?
Yes, but ensure that the ball is sturdy and can hold its shape under the weight of the concrete. A yoga ball is preferred due to its durability and size flexibility.
Q: How do I prevent the concrete from cracking?
Using adhesive mesh tape during the application process and ensuring the concrete cures evenly will help prevent cracking. Additionally, using a high-strength concrete mix is crucial for durability.
Q: Is it necessary to add drainage holes?
Yes, adding drainage holes is essential if you plan to plant directly in the sphere. It allows excess water to escape, preventing root rot and promoting healthy plant growth.
Q: How long will the planter last?
With proper care, including sealing and protection from extreme weather, your concrete sphere planter can last for many years.
Final Thoughts
Creating a concrete spherical planter using a yoga ball is an enjoyable DIY project that results in a unique and stylish addition to your outdoor space. With careful preparation and attention to detail, you can craft a planter that’s both functional and visually appealing.
