Having these materials and tools on hand will ensure that you can proceed with your wooden planter construction without any interruptions. So gather everything you need and let’s get started!

Plan and Measure

In order to successfully build wooden planters, careful planning and precise measurements are essential. Taking the time to plan out the size and shape of your planters will ensure that they fit perfectly in your garden and complement your overall design. Additionally, accurate measurements will guarantee that you have all the necessary parts and materials for a smooth construction process.

To begin, decide on the dimensions of your planters. Consider the available space in your garden and the types of plants you intend to grow. Will you be placing them on a patio, balcony, or directly on the ground? This will determine the size and height of your planters. Once you have a clear idea of the desired dimensions, create a cutting list detailing the required parts.

Pro Tip: It is recommended to cut a “master” piece from one of the decking planks. Use this piece as a template to ensure uniformity in size and shape for the rest of the planters.

Now it’s time to measure and cut the decking planks, timber, and offcuts according to your predetermined dimensions. Use a tape measure or ruler to ensure accuracy. Remember to double-check your measurements before cutting to avoid any mistakes. Taking the time to measure correctly will save you time and effort in the long run.

Example Cutting List:

Part Number of Pieces Dimensions
Decking Planks 4 50cm x 10cm
Treated Timber (legs) 2 70cm x 10cm
Treated Timber (supports) 2 50cm x 2.5cm
Timber Offcuts (corner braces) 4 10cm x 5cm

By following these planning and measuring steps, you’ll be well-prepared to tackle the construction phase of building your wooden planters. So take your time, think through the details, and ensure that your planters are the perfect fit for your garden.

Cutting and Construction

Once you have all the necessary parts cut to size, it’s time to start construction. Use clamps to hold the pieces together as you assemble the corners and legs.

Screw the decking planks to the legs, ensuring a screw in each corner. Attach the remaining side pieces and secure them with screws. Finally, attach the middle legs and slat supports to strengthen the structure of the planter.

Steps for Cutting and Construction
1. Gather all the necessary cut parts
2. Use clamps to hold the pieces together
3. Screw the decking planks to the legs
4. Attach the remaining side pieces
5. Secure the side pieces with screws
6. Attach the middle legs and slat supports for added strength

With these simple steps, you can construct sturdy and durable wooden planters from decking. The clamps will ensure precise assembly, while the screws will provide stability. Remember to follow the cutting dimensions carefully to ensure a perfect fit. Get ready to see your garden transformed with these beautiful planters!

Enhancing the Look

To make your wooden planters look more professional, consider adding some finishing touches. Chamfer the edges of the longer side pieces for a polished look. Chamfer the bottoms of the legs to prevent wood splitting. You can also paint or stain the planters to suit your personal preferences and the aesthetic of your garden. These enhancements will make your planters stand out.

Adding a chamfer to the edges of the longer side pieces gives your wooden planters a clean and refined appearance. The angled edges not only enhance the visual appeal but also provide a smooth finish that prevents splintering.

Paying attention to the bottoms of the legs is equally important. By chamfering them, you can safeguard against potential wood splitting caused by moisture or external factors. This small detail can significantly extend the lifespan of your planters.

If you want to add a pop of color or match your planters with your garden’s aesthetic, try painting or staining them. Choose a high-quality outdoor wood paint or stain that complements your outdoor space. Whether you prefer a classic white finish or a bold and vibrant color, painting or staining your planters will give them a personalized touch.

Remember, the finishing touches on your wooden planters are the key to making them truly stand out. Consider your garden’s overall style and choose the enhancements that best suit your taste. Whether it’s chamfering the edges or adding a splash of color, these simple yet effective techniques will transform your planters into stunning focal points in your garden.

Painting or staining – Personalizes the planters

Adding the Base and Lining

The base of the wooden planter is crucial for stability and proper drainage. To ensure stability, you need to consider the type of surface the planter will be placed on. If it’s going on soil, a cardboard base can be used to provide support. However, if you’re placing the planter on a concrete patio or any hard surface, you’ll need to take additional steps.

If your planter will be on a concrete patio, it’s important to create drainage holes in the base. These holes will prevent waterlogging and help maintain the health of your plants. To line the planter, use a landscape fabric liner that can be stapled inside. This liner acts as a barrier, allowing water to drain while preventing soil from escaping.

Another important consideration is protecting the wood of the planter. To avoid direct contact between the soil and the wood, line the inside of the planter with plastic. This lining will help protect the wood from moisture and extend the lifespan of your planter.

Filling and Planting

Once your wooden planters are constructed and lined, it’s time to fill them with soil or compost. Adding the right amount of soil or compost is crucial for the health and growth of your plants. I recommend following these steps to ensure successful planting in your decking planters:

  1. Add a layer of broken garden pots or stones at the bottom of the planter. This layer will help with drainage, preventing water from sitting at the roots of your plants.
  2. Fill the planters with the appropriate amount of multi-purpose compost. The depth of the compost should be enough to accommodate the root systems of your chosen plants.
  3. Consider mixing in some organic matter, such as well-rotted manure or compost, to enrich the soil and provide nutrients to your plants.
  4. Now it’s time to start planting! Choose plants that are suitable for the size and location of your wooden planters.
  5. If you’re not sure which plants to choose, you can consult gardening books or websites, or seek advice from your local garden center.
  6. When planting, make sure to space the plants properly to allow for their growth. Follow the specific planting instructions for each type of plant.
  7. Water your newly planted flowers, herbs, or vegetables thoroughly after planting, and continue to water them regularly as needed.

By following these planting guidelines, you can create a thriving garden in your wooden planters and enjoy the beauty of nature right in your own backyard.

My Planting Tips:

When choosing plants for your decking planters, consider the amount of sunlight the area receives. Some plants thrive in full sun, while others prefer partial shade. It’s important to select plants that match the sun exposure of your planter location to ensure their successful growth.
