Key Takeaways
- A wooden planter box is a charming addition that suits a vast array of design preferences and spaces.
- Selecting a durable timber and considering a design that matches your skill level will ensure longevity and satisfaction.

Types of Timber for Planter Boxes
When you’re selecting timber for your planter boxes, understanding the difference between hardwood and softwood, as well as choosing sustainable options, are key considerations for a successful and environmentally friendly project.
Hardwood Versus Softwood
Hardwood comes from deciduous trees that lose their leaves annually—think trees like teak and mahogany. Hardwoods are generally more durable and long-lasting for planter boxes, but this often comes at a higher cost. On the other hand, softwoods are from coniferous trees, which are evergreen. Cedar and pine are typical softwoods used for planters. They’re more affordable and easier to find but may not last as long as hardwood options without proper treatment.
Choosing Sustainable Timber
When it’s time to pick out your timber, sustainability should be top of mind. Look for woods like cypress or redwood, which are naturally resistant to decay and don’t require harmful chemicals to maintain their integrity. Always check for timber that’s certified by organisations like the Forest Stewardship Council (FSC), which ensures that the wood has been sourced responsibly. Remember, your choice to support sustainably managed forests can help reduce your environmental footprint.
Here’s a tip: Local timber is often the most sustainable option, as it reduces the carbon footprint associated with transportation. Check availability in your area and consider using local woods for your planters.
Designing Your Planter Box
Creating your own planter box from wood offers a customisable and personal touch to your gardening space. Focusing on size, shape, and practical features like drainage will ensure your planter box is both aesthetically pleasing and functionally sound.
Size and Shape Considerations
Your planter box design should start with considering size and shape, as these will determine which plants you can grow and where the box can be placed. For decks and small areas, a long, narrow planter might be best. Larger spaces may allow for more creative shapes, such as L-shaped boxes that can double as corner pieces. Ensure the depth of the box can accommodate the root growth of your chosen plants. Common sizes for a basic rectangular planter box might include:
- Small: 60 cm length x 30 cm width x 30 cm depth
- Medium: 90 cm length x 45 cm width x 40 cm depth
- Large: 120 cm length x 60 cm width x 40 cm depth
Drainage and Lining
Drainage is crucial in preventing waterlogged soil and root rot. Your planter box should have holes at the bottom to allow excess water to escape. Covering these holes with a mesh screen can prevent soil from washing out. Additionally, lining your planter box with a waterproof material such as plastic sheeting or a geotextile fabric will protect the wood from moisture while still allowing water to drain. It’s important to use exterior-rated hardware for assembly to ensure your planter lasts in the outdoor elements.
Building Your Planter Box
Creating a wooden planter box is a practical way to add charm and functionality to your outdoor space. By gathering the right tools and materials, and following clear assembly instructions, you can craft a sturdy and attractive planter box perfectly suited to your garden.
Tools and Materials
To begin constructing your planter box, you’ll need the following:
- Measuring tape
- Saw (hand saw or power saw)
- Drill with bits
- Screws (galvanised for outdoor use)
- Wood (treated timber for durability)
- Wood glue (exterior grade)
- Sandpaper (medium and fine grit)
- Protective gear (safety glasses and gloves)
Make sure to choose wood that’s suitable for outdoor use, such as treated pine, to ensure your planter box withstands the elements.
Assembly Instructions
- Measure and Cut:
First, measure and mark the timber to the desired dimensions of your planter box. Cut the pieces carefully with your saw. - Drill Pilot Holes:
To avoid splitting the wood, drill pilot holes where you’ll drive the screws in. - Assemble Base and Sides:
Apply wood glue to the edges before screwing the base to the side panels, creating a box shape. - Attach Bottom:
Secure the base with screws, ensuring adequate drainage. - Sanding:
Once assembled, sand the planter box with medium grit sandpaper, followed by a finer grit for a smooth finish.
By adhering to these guidelines, you’ll have a bespoke wooden planter box, ready for varnishing or painting, and then filling it with your favourite plants.
Treatment and Maintenance
Proper treatment and maintenance can greatly extend the life and beauty of your planter boxes. It’s essential to weatherproof your wood and commit to ongoing care to fend off damage from the elements.
Weatherproofing
Before you place a single plant into your new planter box, make sure it’s weatherproof. This can involve applying a sealant that’s appropriate for the wood type and suited for your climate. For woods such as pine, which aren’t naturally weather-resistant, this step is critical to prevent rot.
- Choose a sealant that’s non-toxic to plants.
- Apply at least two coats for optimum protection.
Ongoing Care
Once treated, your wooden planter boxes will need regular maintenance to keep them looking their best and to prevent deterioration.
- Inspect regularly: Look for signs of wear such as chipping paint or water damage.
- Re-seal as needed: Vital for extending the life of the planter; some products offer up to ten years of protection.
Placement and Planting
When setting up your wood planter box, the importance lies in finding the perfect spot and using the best soil mix and plants for that location. Your choice can greatly affect how your plants grow.
Selecting the Right Location
The right spot for your planter box should provide the ideal balance of sunlight and shade that matches the needs of your intended plants. Consider the direction of the sunlight throughout the day; an east-facing position benefits from the morning sun, which is less intense, while a west-facing placement will expose plants to the strong afternoon sun. Remember to think about the weight of the planter and choose a location that can support it, especially if the box is placed on a deck or a balcony.
Soil and Plant Recommendations
Your planter box needs a quality potting mix that caters to good drainage and nutrient retention. It’s advisable to look for a mix that includes compost, perlite, or vermiculite to encourage healthy plant growth.
As for the plants, choose species that are well-suited to the depth and size of your box. Deep-rooted plants like tomatoes will require a deeper box, while herbs like basil and parsley can thrive in shallower ones. Make sure to space your plants properly; overcrowded plants compete for nutrients and are more susceptible to disease. Use a guide on gardening in planter boxes for precise spacing and depth details.
