Concrete planters have become a favorite among home décor lovers—and for good reason. They’re modern, durable, minimalist, and surprisingly easy to make yourself. Whether you’re a plant enthusiast or a DIY hobbyist looking to try something new, concrete planters are a fun and rewarding project that adds a stylish touch to any space.

In this guide, we’ll walk through everything you need to know to make your own beautiful DIY concrete planters from scratch.

🌿 Why Choose Concrete Planters?

Concrete planters are popular for several reasons:

  • Durability: They last for years and hold up well indoors or outdoors.
  • Modern aesthetic: Their smooth, clean finish works with any décor style—from industrial to minimalist.
  • Customizable: You can create any shape, color, or size you want.
  • Affordable: Concrete mix is inexpensive and goes a long way.

What You’ll Need

Before you begin, gather the following materials:

Materials

  • Quick-setting concrete mix
  • Water
  • Two containers (one larger, one smaller) to act as molds
  • Cooking oil or spray for mold release
  • Sandpaper (medium and fine grit)
  • Gloves
  • Plastic sheet or drop cloth

Optional Add-ons

  • Concrete pigment
  • Painter’s tape for patterns
  • Acrylic sealer
  • Decorative stones, pebbles, or gold leaf

🛠️ Step-by-Step Guide to Making Concrete Planters

Step 1: Prepare Your Molds

Choose any two containers that fit inside each other to create the planter shape.
Examples: yogurt tubs, plastic cups, juice cartons, silicone molds.

Spray both molds lightly with oil—this makes it easy to remove the concrete once dry.

Step 2: Mix the Concrete

Follow the instructions on your concrete mix.

  • Combine concrete and water in a bucket.
  • Stir until the texture is like thick pancake batter—smooth, but not watery.
  • Add pigment if you want a tinted planter.

Step 3: Pour the Concrete

  • Fill the larger mold halfway with the concrete mixture.
  • Press the smaller mold into the center, pushing down until you reach your desired depth.
  • Make sure the walls of your planter are even.

Tap the sides gently to release air bubbles—this helps avoid holes and cracks.

Step 4: Let It Cure

Let the concrete sit undisturbed for 24–48 hours.

Covering it lightly with plastic slows the drying process and prevents cracking.

Step 5: Remove the Molds

Once fully hardened:

  • Gently twist or pull out the inner mold.
  • Peel away the outer mold to reveal your planter.

If needed, use sandpaper to smooth edges or imperfections.

Step 6: Seal (Optional)

If you’re placing the planter outdoors or using it for moisture-sensitive plants, apply an acrylic sealer.
This protects the concrete and gives it a clean, finished look.

🎨 Creative Ways to Customize Your Concrete Planter

  • Add geometric patterns with tape before painting.
  • Mix in color pigments for pastel or bold hues.
  • Use textured molds (basket weave, ribbed cups, silicone shapes).
  • Add gold leaf accents for a luxury touch.
  • Create drainage holes using a straw or dowel during molding.

Your creativity is the only limit!

🌱 Best Plants for Concrete Planters

Concrete planters pair well with:

  • Succulents
  • Cacti
  • Snake plants
  • Pothos
  • Small ferns
  • Herbs (if sealed properly)

They’re also great outdoors for flowers or small shrubs.

Final Thoughts

DIY concrete planters are a stylish and surprisingly simple project that instantly elevates your indoor or outdoor garden. With just a small amount of concrete and creativity, you can design unique planters that fit your personal style and last for years.
