Creating a charming garden or revitalizing a dull balcony often starts with the right containers, but purchasing expensive planters is not the only solution. With a little creativity and some basic DIY skills, you can assemble beautiful and functional display boxes without breaking the bank. These cheap ideas for planter boxes allow you to customize the size, shape, and aesthetic to perfectly fit your space, turning overlooked materials into stunning gardening assets.
Upcycling Household Items
The most accessible and zero-cost approach to building display boxes involves looking around your home for discarded items. This method is not only budget-friendly but also environmentally sustainable, giving new life to objects that would otherwise end up in landfills.
Boot Cans and Tins
Empty coffee tins, soup cans, and vegetable cans are perfect for small herb gardens or succulent arrangements. To prevent rust, simply coat the interior with a clear sealant or line the inside with a small plastic bag. You can also remove the labels and decorate the exterior with washi tape or paint to match your decor.
Wire Baskets and Crates
Supermarket fruit baskets and wooden shipping crates are excellent foundations for creating airy display boxes. For wooden crates, lining the bottom with heavy-duty plastic sheeting or landscape fabric will contain the soil while allowing the wood to breathe. These structures are ideal for creating vertical gardens when mounted on a wall or fence.
Constructing with Basic Materials
If you prefer a more tailored design, constructing your own box from raw materials is both economical and rewarding. The key is to choose materials that are durable enough to hold moisture while remaining affordable.
Tiered Block Systems
Stacking concrete blocks is a highly effective way to create a vertical planter wall at a fraction of the cost of traditional stonework. Simply arrange the blocks on a stable surface, fill the centers with soil, and plant trailing flowers like petunias or hardy herbs. This method provides excellent drainage and a modern, industrial aesthetic.
Rubbermaid and Storage Bins
Large plastic storage containers are an underrated resource for gardeners. By drilling several holes in the bottom for drainage, you create a durable, waterproof liner that can be slipped into a decorative outer box. This technique protects the interior from UV damage while allowing you to swap out the exterior for seasonal looks.
Creative Wood and Frame Designs
For a rustic or farmhouse vibe, reclaimed wood and simple framing techniques offer a high-impact visual result using minimal resources.
Pallet Planters
Wooden pallets are readily available and provide ample material for building deep, raised beds. By removing every other board, you create gaps for plants to grow through while reducing the total amount of wood needed. Ensure the pallet is heat-treated (marked with HT) rather than chemically treated to ensure safety for growing food.
Window Box Repurposing
Old wooden window frames are essentially ready-made planter boxes. By attaching them to a wall or fence and lining them with plastic, you create a classic garden feature that offers excellent drainage and root insulation. These are particularly effective for maximizing shallow spaces like railings or narrow pathways.
Material Comparison and Selection Guide
Choosing the right base material depends on your budget, the climate, and the types of plants you wish to grow. The table below compares the most common affordable options to help you decide.
| Material | Cost | Best For | Durability |
|---|---|---|---|
| Plastic Containers (Reused) | Free | Herbs, Seed Starting | Moderate (UV Degradation) |
| Reclaimed Wood (Pallets) | Very Low | Rustic Raised Beds | Low to Moderate (Weather Dependent) |
| Concrete Blocks | Low | Tiered Walls, Modern Looks | High (Weather Resistant) |
| Metal Tins (Upcycled) | Free | Small Accents, Indoors | Moderate (Rust Prone) |
Maintenance and Longevity Tips
Even the most ingeniously constructed cheap planter boxes will require some basic maintenance to ensure they last for multiple growing seasons. Proper care prevents rot, rust, and structural failure.
Regardless of the material you choose, adding a drainage layer is non-negotiable. Place a few inches of gravel or broken pottery at the bottom of the box before adding soil. This prevents the roots from sitting in water, which is the primary cause of plant death in containers. Additionally, elevating wooden boxes slightly off the ground using stones or bricks allows air to circulate underneath, significantly extending the life of the wood.
