Transform Your Outdoor Space: DIY Large Outdoor Planters
Elevate your garden or patio with stunning, handcrafted large outdoor planters. Not only is creating your own planters a rewarding DIY project, but it's also a cost-effective way to add a personal touch to your outdoor space. This comprehensive guide will walk you through the process, from selecting materials to designing and building your perfect large outdoor planters.
Benefits of DIY Large Outdoor Planters
Before we dive into the how-to, let's explore the advantages of crafting your own large outdoor planters:
- Cost-effective: Buying large planters can be expensive. Building your own allows you to create multiple planters for the price of one store-bought.
- Customizable: DIY planters let you choose the size, shape, and style that best suits your space and plants.
- Durable: When built correctly, DIY planters can last for years, even decades, with proper care.
- Eco-friendly: By reusing materials and reducing waste, you're contributing to a greener environment.
Materials Needed
To create your large outdoor planters, you'll need the following materials:

- Concrete or cement mix
- Water
- Large plastic containers or forms (optional, for a uniform shape)
- Gravel or small stones
- Drainage holes (if not using a plastic container with pre-made holes)
- Plastic sheeting or a tarp
- Trowel or shovel
- Gloves and safety glasses
Designing Your Planters
Before mixing your concrete, decide on the size, shape, and number of planters you want to create. Consider the plants you'll be using and the space available. You can create simple, uniform planters or get creative with unique shapes and sizes.
Building Your Planters: Step-by-Step
Preparation
Choose a dry, sunny day for your project. Lay down plastic sheeting or a tarp to protect your work surface. If using plastic containers as forms, ensure they're clean and free of any residue.
Mixing Concrete
Follow the instructions on your concrete mix to create a smooth, workable consistency. Typically, this involves combining one part cement with two to three parts water. Be sure not to add too much water, as this can weaken the final product.

Creating the Planter Base
Using your trowel or shovel, spread a layer of concrete about 1-2 inches thick at the bottom of your container or form. If you're not using a container, create a base on your work surface, ensuring it's level and the correct size for your planter.
Adding Drainage
Before the concrete sets, create drainage holes. If using a plastic container with pre-made holes, skip this step. Otherwise, use a drill or a sharp object to create several holes in the base of your planter.
Building Up the Sides
Add layers of concrete to the sides of your planter, building up to your desired thickness. Allow each layer to set slightly before adding the next. Be sure to create a slight lip at the top to hold in soil and prevent water from spilling over.

Finishing Touches
Once your planter is at the desired height, smooth the top edge with your trowel for a clean, finished look. Allow the planter to cure according to the manufacturer's instructions, usually around 24-48 hours.
Adding Gravel
After curing, turn your planter upside down and gently tap it to remove it from the form (if using). Fill the planter with a layer of gravel or small stones to improve drainage and prevent soil from clogging the holes.
Caring for Your DIY Large Outdoor Planters
To ensure your planters last for years to come, follow these care tips:
- Seal the exterior with a concrete sealer to protect against moisture and stains.
- Allow water to drain completely after watering to prevent root rot.
- Repair any cracks or chips promptly to prevent further damage.
- Store your planters in a protected area during harsh winters to prevent freezing and thawing cycles from causing damage.
Inspiration and Ideas
Now that you've learned how to create your own large outdoor planters, it's time to get inspired! Consider these ideas to make your planters truly unique:
- Add decorative elements, such as mosaic tiles or seashells, to the exterior.
- Create a planter bench by building a long, narrow planter with a ledge for seating.
- Design a tiered planter to save space and create visual interest.
- Use repurposed materials, like old tires or wooden barrels, to create eco-friendly planters.
With these tips and ideas, you're ready to create stunning, large outdoor planters that will transform your space and showcase your DIY skills. Happy building!
