Introduction
Concrete planters look great in a garden or even inside your home. If you are looking for the perfect planter for a plant in your home this is the way to go. They can easily be painted to match your home’s décor or paint can be even used in the mix to create light-colored concrete. Here is a guide on how to mix paint and concrete.
Creating concrete planters not only adds beauty to your space but also allows for a unique DIY project that you can customize according to your personal style. The versatility of concrete as a medium makes it an ideal choice for crafting planters that can withstand various weather conditions while also being aesthetically pleasing. Concrete planters are durable, weather-resistant, and can last for many years with the right care, making them a fantastic addition to any space.
Moreover, this DIY project is not just about aesthetics; it also promotes sustainable practices. By making your own planters, you can reduce waste by repurposing materials and using local resources. This adds an eco-friendly touch to your gardening efforts. Whether you are an experienced gardener or just starting, creating concrete planters can be a rewarding and enjoyable experience.
The process of making concrete planters is a simple one and can be achieved by anyone. All you need is the following tools to get you started.
The materials that you will need for the concrete planters
Concrete ready mix bag
Old plastic food containers in different sizes or some other plastic shape that can be used as a mold
Non-stick cooking spray
Straws that are sturdy enough to be placed inside the mold
Plastic sheeting
Plastic bucket that you can use for mixing the concrete
Sturdy stick to mix with or a trowel
Measuring stick
Measuring cup
Water
Sanding pad
Rubber coated gloves
Outdoor patio paint (it’s made of the same material after all)
Optional: concrete drill bit and hammer drill if you don’t want to use straws for drainage
14 steps for concrete planters
Step 1: Thoroughly clean and dry the plastic food containers. Basically, you want one bigger one and one that fits inside that while leaving some space on the sides so the concrete can get all around it. I think it’s good when you can fit one finger all around the small cup.
Step 2: Spray the mold (plastic container) with non-stick cooking spray. Using a light coat of non-stick cooking spray allows the concrete planter to easily remove from the plastic container/mold.
Step 3: Now we need to make drainage holes. There are two easy ways to do it. The first one is to use straws on the mold, the second one is drilling the holes after the concrete has cured. Proper drainage is crucial for plant health, preventing excess water from accumulating in the bottom of the planter.
To use the straw tactic, you will need to cut holes in the bottom of the larger mold and the bottom of the smaller plastic container that gets set inside the larger one. Once the holes are punctured place straws through the holes in the smaller container and then insert the same straw through the hole in the larger container.
You don’t have to glue them or tape them; small holes won’t have concrete coming through them. You just need small enough holes for the straw to go through.
Step 4: Now you will want to spread out the plastic sheeting and put on the rubber gloves. There is always a little bit messy when you work with concrete so it’s good to cover your working spot. Concrete can dry your skin fast, so rubber gloves will protect against that. You can also use your hands a bit that way if you have trouble getting the concrete in the mold.
Step 5: Mix the concrete according to the manufacturers directions. Depending on the size of the bag, it can be a lot. If possible, pick the amount you need for your planters project. If you can’t get a small size bag, I got you covered.
First, place the amount of dry concrete mix in the bucket that you need to fill the planters mold. You can use the same size plastic container to fill it or measure by eye. Then start adding water little by little. It’s best to err on the side of caution and add less water at first; you can always add more if needed.
Usually, you need something like 1/5 of the amount of the concrete, but add carefully. You don’t want it to be too runny. When it’s hard enough to make a ball in your hand, but still soft enough to mold easily and pour from the bucket it should be good enough for this.
Step 6: Now pour the concrete into the mold. Be careful that it doesn’t remove the straw. If it does you will no longer have a drainage hole and have to use the drill to make them. Ensuring that the concrete settles evenly is important, so take your time during this step.
When you reach the level of your smaller plastic container give the mold little taps to the bottom and sides to help the first air bubbles escape. Then continue pouring more until you have a mold full of concrete with the inner plastic container inside as well.
Step 7: Gently tap the mold a lot of times. This allows any trapped bubbles to escape. If you skip this step the surface of your concrete planter might have small craters where the bubbles were left. If you like this look, you might give it a try as well. Additionally, consider using a vibrator tool if you want a professional finish, as it can help remove bubbles more effectively.
Step 8: Add some rocks or something a little heavy to the smaller container that is set inside the mold. Another good way is to use some kind of wood piece on top of the mold so the smaller container cannot lift higher than that of the surface.
This will help to keep the container in the cement since it likes to rise. Make sure that the concrete has gotten into all the nooks and crannies before you leave it to cure for a while.
Step 9: Sit your mold on a level surface. If the surface is not level then the plant holder will not be either, depending on how thick or thin the concrete is. A level surface is essential for ensuring your planter looks professional and functions correctly.
Step 10: Before the cement is going to solidify, remove the inside mold only, not the straws. You know this when you touch the surface of the concrete planter and it’s hard enough to give in, but it can hold its form. You will notice when you remove the inner container.
Step 11: Sometimes after you have removed the inner container, you can remove the straws. You could give it as long as 8 hours before you remove them, depending on the conditions. If it’s very hot the concrete might cure faster, while in cold conditions it will take longer. In indoor conditions, I’d say 8 hours. Keeping an eye on the weather is essential; high humidity can also affect the curing time.
Step 12: After 24 hours, remove the outer container by shaking. If you used cooking oil, it should come off easily. Use the sanding pad to sand away any rough edges and sides. It’s easy to sand the next day, but after the concrete keeps on curing, it will get harder and harder. This step will give your planter a polished, professional look.
Step 13: Let the planter dry for another 48 hours. I give it three days’ time just to be sure. This really depends on how thick the concrete planter is. Something like a concrete slab has to cure for 28 days. Remember, patience is key in achieving the best results!
If you didn’t use straws to make drainage for water, you can use a hammer drill and a concrete bit to drill them now. If you don’t own a hammer drill, a power drill can do it as well, but you have to do it 24 hours after the pour so the concrete won’t be so hard yet.
Step 14: Use your outdoor paint to paint the planters in the style that you choose. Then you just need to let it dry. Consider using a sealant after painting for added protection against the elements.
Congratulations! Now you just need to plant a plant in the homemade planter and you are done. Take a moment to admire your work; you’ve created something beautiful and functional!
Tips for Enhancing Your Concrete Planters
Now that you’ve made your concrete planter, consider enhancing it further. Here are some tips to elevate the beauty and functionality of your creation:
1. Experiment with Colors and Textures
While you can use outdoor paint to color your planters, you can also experiment with different types of concrete stains or even add color pigments during the mixing phase. This opens up a myriad of possibilities for customizing the appearance of your planter. Additionally, you could incorporate textures into your design by using different molds or adding aggregates like gravel to the mix for a unique finish. You might even consider using a sponge or brush technique to create interesting patterns on the surface.
2. Add Decorative Elements
Once your planter is dry and painted, think about adding decorative elements such as stones, shells, or mosaic tiles to the surface. This not only enhances the visual appeal but also gives your planter a personal touch. You can arrange these elements in patterns or designs that reflect your style. For an even more unique look, consider embedding small figurines or plant markers into the concrete before it sets.
3. Provide Adequate Drainage
While your planter may already have drainage holes, consider adding a layer of rocks or gravel at the bottom before pouring in the soil. This helps to improve drainage and prevent water from pooling at the bottom, which can lead to root rot in your plants. It’s an essential step for maintaining the health of your plants. Remember, healthy plants are happy plants!
4. Consider Plant Selection
When selecting plants for your new concrete planter, take into account the size and depth of the planter as well as the sunlight conditions of the area. Succulents and cacti are great low-maintenance options for smaller planters, while larger planters can accommodate a variety of flowers, herbs, or even small shrubs. Additionally, you might want to think about companion planting, where you choose plants that can benefit from each other’s presence.
5. Seasonal Themes
As seasons change, consider updating the decor of your planters to reflect current holidays or seasonal themes. For example, you can decorate your planters with small pumpkins in the fall or colorful flowers in the spring. This not only keeps your decor fresh but also engages you in seasonal crafting activities. Hosting seasonal planting events can also be a fun way to involve friends and family in your gardening journey!
Additional Considerations for Your Concrete Planters
While crafting your concrete planters is an exciting project, there are additional considerations to keep in mind that can enhance the longevity and functionality of your creations. Here are a few extra tips to ensure your planters not only look good but also serve their purpose effectively.
1. Weather Resistance
Concrete is naturally strong, but it can be susceptible to cracking in extreme weather conditions. To combat this, consider using a concrete sealant after the planters have dried completely. This will help protect the surface from moisture and prevent damage from freezing and thawing cycles. Sealants can also enhance the color and finish of your planters, giving them a polished look.
2. Insulation for Plant Roots
Concrete can retain heat, which is beneficial in cooler climates, but it can also become hot in direct sunlight, potentially harming your plants. To mitigate temperature fluctuations, consider adding a layer of insulating material inside the planter. Materials such as foam or even layers of mulch can help regulate the temperature, ensuring a stable environment for root growth.
3. DIY Customizations
Embrace your creativity by customizing your planters even further. You might want to add hooks or brackets for hanging plants, or create a tiered planter for a more dramatic effect. Experimenting with different shapes, such as geometric or organic forms, can also make your planters standout pieces in your home or garden.
4. Maintenance and Care
Once your planters are in use, regular maintenance is key to keeping them in good shape. Be sure to check for any signs of wear or damage, and clean them periodically to prevent dirt and algae build-up. A simple wash with water and a soft brush can help maintain their appearance. If you notice any cracks or chips, repair them promptly with a concrete patching compound to prevent further damage.
5. Share Your Creations
In the spirit of community and sharing, consider showcasing your finished concrete planters on social media or local gardening groups. By sharing your DIY journey, you can inspire others to take on their own concrete projects. Engage with fellow DIY enthusiasts to exchange tips, ideas, and even planters to trade or gift.
