Types of Cement for Succulent Planters
Not all cement is created equal. Choosing the right type is crucial for the success of your planter. Here’s a breakdown of the most common options:
- Portland Cement: This is the most readily available and widely used type of cement. It’s strong, durable, and relatively inexpensive. However, it can be quite alkaline initially, which could affect your succulents. Proper curing helps mitigate this.
- Hydraulic Cement: This type sets quickly and is water-resistant, making it ideal for planters that will be exposed to the elements. It’s a good choice for projects where you need a fast turnaround.
- White Cement: Similar to Portland cement in properties, but it’s white in color. This allows for brighter colors when adding pigment or for a clean, minimalist look.
- Rapid Set Cement: This cement cures extremely quickly, often within an hour or two. It’s great for small projects or when you need to de-mold your planter quickly.
Table: Cement Types and Their Properties
| Cement Type | Setting Time | Water Resistance | Color | Best For |
|---|---|---|---|---|
| Portland Cement | Moderate | Moderate | Gray | General-purpose planters |
| Hydraulic Cement | Fast | High | Gray | Planters exposed to weather |
| White Cement | Moderate | Moderate | White | Colored or minimalist planters |
| Rapid Set Cement | Very Fast | Moderate | Gray | Small, quick projects |

Step-by-Step Guide to Making Your Own Cement Succulent Planter
Now for the fun part! Follow these steps to create your own beautiful and functional cement succulent planter.
Step 1: Prepare Your Molds
Choose two containers – one that will form the inside of the planter and one that will form the outside. Plastic buckets, cardboard boxes lined with plastic, or even yogurt containers can work well. The key is to have a smaller container that fits inside the larger one, leaving a space for the cement to create the walls of the planter.
Apply a release agent (vegetable oil, cooking spray, or a commercial mold release) to the inside of the larger container and the outside of the smaller container. This will prevent the cement from sticking and make it easier to remove the planter once it’s cured.
Step 2: Mix the Cement
The ideal cement mixture is typically a ratio of 1 part cement to 2 parts sand. This creates a strong and durable concrete mix. Add water gradually until you achieve a thick, pancake batter-like consistency. Be careful not to add too much water, as this will weaken the cement.
If you’re adding pigment, mix it into the dry cement and sand before adding water for even color distribution.
Step 3: Pour the Cement
Pour a layer of cement into the bottom of the larger container, about 1-2 inches thick, depending on how thick you want the base of your planter to be. This will form the bottom of the planter.
Carefully center the smaller container inside the larger container, pressing it down into the cement layer. Make sure it’s evenly spaced from the sides of the larger container.
Pour cement into the gap between the two containers, filling it to the desired height of the planter walls.
Step 4: Remove Air Bubbles
Air bubbles can weaken the cement and create imperfections in the surface. To remove them, gently tap the sides of the mold with a rubber mallet or use a vibrating sander against the mold. This will help the air bubbles rise to the surface.
Step 5: Curing the Cement
Curing is essential for the strength and durability of your cement planter. Cover the mold with plastic wrap to prevent the cement from drying out too quickly. Keep the mold in a cool, shaded area for at least 24-48 hours.
After the initial curing period, carefully remove the inner container. You may need to gently tap or wiggle it to loosen it.
Continue to cure the planter for another 7-10 days, keeping it damp by spraying it with water daily. This allows the cement to fully hydrate and harden.
Step 6: Demold and Finish
Once the curing process is complete, carefully remove the outer container. You may need to use a rubber mallet or a screwdriver to gently pry it away from the cement.
Use sandpaper to smooth any rough edges or imperfections on the planter. You can also use a wire brush to create a textured finish.
Step 7: Drill Drainage Holes
Drainage is crucial for succulent health. Use a drill with a masonry bit to drill drainage holes in the bottom of the planter. The number and size of the holes will depend on the size of the planter and the type of succulents you plan to plant.
Step 8: Seal the Planter (Optional but Recommended)
Sealing your cement planter is highly recommended. Cement is naturally porous and alkaline. Sealing helps prevent water from seeping into the cement, which can cause it to crack or crumble over time. It also prevents the leaching of lime (calcium hydroxide) from the cement, which can raise the pH of the soil and harm your succulents.
Use a concrete sealer specifically designed for planters. Apply it according to the manufacturer’s instructions.
Creative Ideas for Cement Succulent Planter Designs
The beauty of making your own cement planters is the freedom to create unique designs. Here are some ideas to inspire you:
- Geometric Shapes: Experiment with different mold shapes to create geometric planters. Think cubes, pyramids, hexagons, or even more complex shapes.
- Textured Surfaces: Add texture to your planters by pressing objects into the wet cement, such as leaves, shells, or pebbles.
- Ombre Effect: Create an ombre effect by gradually adding pigment to the cement mix as you pour it into the mold.
- Multi-Tiered Planters: Create a multi-tiered planter by stacking different-sized planters on top of each other.
- Hanging Planters: Add hooks or ropes to your planters to create hanging succulent displays.
- Embedded Decorations: Embed glass beads, tiles, or other decorative elements into the cement for a unique look.

Caring for Your Succulents in Cement Planters
Proper care is essential for keeping your succulents healthy and thriving in their cement planters. Here are some tips:
- Watering: Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering is the most common cause of succulent death.
- Sunlight: Provide your succulents with plenty of sunlight, ideally at least 6 hours per day.
- Soil: Use a well-draining succulent potting mix. This will prevent the soil from becoming waterlogged.
- Fertilizing: Fertilize your succulents sparingly, using a balanced liquid fertilizer diluted to half strength.
- Drainage: Ensure that your planter has adequate drainage holes to prevent water from accumulating in the bottom.
- Winter Protection: In cold climates, protect your succulents from frost and freezing temperatures by bringing them indoors or covering them with frost cloth.
Troubleshooting Common Issues
Even with the best care, you may encounter some issues with your succulents in cement planters. Here are some common problems and how to address them:
- Yellowing Leaves: This can be a sign of overwatering, underwatering, or nutrient deficiency. Adjust your watering schedule accordingly and fertilize if necessary.
- Soft, Mushy Leaves: This is usually a sign of root rot, caused by overwatering. Remove the affected leaves and allow the soil to dry out completely. You may need to repot the succulent in fresh soil.
- Leggy Growth: This is a sign of insufficient sunlight. Move your planter to a sunnier location or provide supplemental lighting.
- White Powdery Coating: This could be powdery mildew, a fungal disease. Treat with a fungicide.
- Pests: Mealybugs, aphids, and spider mites can infest succulents. Treat with insecticidal soap or neem oil.
