Understanding Timber for Planter Boxes
When you’re considering building a planter box, the timber you choose will significantly affect its durability, appearance, and maintenance levels. Here’s a brief guide to selecting the right timber for your planter boxes.
Natural Rot-Resistance:
- Cypress: Known for its natural rot-resistance, making it a solid choice for longevity. However, be aware that it’s not as resistant to pests as some other options.
- Teak: Although more expensive, teak boasts impressive durability and is highly resistant to rot and decay. It also possesses a natural beauty that many gardeners prefer.
Treated Timber:
- If budget is a constraint, treated pine is an affordable choice. It’s treated to resist moisture and decay, but be sure the treatment is safe for use around soil and plants.
Australian Hardwoods:
- Local timbers like jarrah can be excellent choices due to their strength and resistance to the elements. Moreover, supporting local timber can contribute to reducing your carbon footprint due to lower transportation emissions.
Construction Tips:
- Ensure you select timber pieces free from defects.
- Use galvanised screws or nails to avoid rust.
Maintenance:
- Timber can require sanding and resealing periodically to maintain its appearance and durability. Keep this in mind when making your selection.
Remember to always consider the environmental impact of your timber choice. Look for sustainably sourced options to ensure your garden is as green as the plants you’re nurturing.
Designing Your Timber Planter Box
Creating your timber planter box begins with careful planning to ensure it meets your gardening needs. We’ll walk through choosing sizes, selecting the best wood, and implementing effective drainage.
Choosing the Right Dimensions
To suit your space and the plants you want to grow, start by determining the ideal size of your planter box. A compact box might be 40cm by 40cm for herbs, while larger veggies might require 90cm by 180cm. Consider the depth too—30cm is fine for shallow roots, but 45cm or more suits deep-rooted plants.
Selecting Timber Species
Choose a timber that’s durable and suitable for outdoor use. Treated pine is cost-effective and readily available. For a more natural look, hardwoods like jarrah or merbau resist rot without chemicals. Cedar is another excellent choice, known for its natural resistance to decay, though it can be pricier.
Drainage Considerations
Proper drainage is crucial to prevent root rot. Drill multiple 1cm holes in the base of the planter box every 15-20cm. To enhance drainage, line the bottom with a layer of geotextile fabric, followed by a 5cm layer of coarse gravel or large pebbles. This setup ensures excess water drains away effectively while keeping soil in place.
Building Your Timber Planter Box
Constructing a timber planter box can be a rewarding DIY project. You’ll create a space for growing plants and add a touch of nature to your outdoor area. Follow these steps to ensure your planter is functional and aesthetically pleasing.
Tools and Materials
To get started, you’ll need the following tools and materials:
- Timber: Choose a type of wood that suits your climate and aesthetic preferences, such as treated pine or cedar.
- Measuring tape and pencil: For accurate measurements.
- Saw: To cut the timber to size.
- Drill or screwdriver: To assemble the pieces.
- Screws: Galvanized or stainless steel to prevent rust.
- Sandpaper or electric sander: To smooth the timber surfaces.
- Paint brush or roller: For applying stains or sealants.
- Safety equipment: Gloves and goggles for protection.
Ensure all the materials are ready and tools are in working order before commencing assembly.
Assembly Instructions
To assemble your timber planter box, follow these instructions:
- Cut Timber: Based on the dimensions of your desired planter, cut two longer and two shorter lengths for the sides, and a base piece.
- Example: For a 100cm x 50cm planter box, cut two 100cm lengths and two 50cm lengths.
- Drill Pilot Holes: In the shorter lengths to avoid splitting the wood.
- Tip: Space the holes evenly for a secure fit.
- Screw Together: Attach the sides to form a rectangle, then fasten the base.
- Remember: The pilot holes face the inside of the planter.
After assembly, ensure the box is stable and square.
Finishing and Maintenance
The final steps are finishing and maintenance:
- Sand: Smooth all surfaces to remove splinters or rough edges.
- Stain or Seal: Choose an appropriate product to treat the wood, making sure it’s suitable for outdoor use and non-toxic to plants.
- Consider: A waterproof sealer to extend the life of your planter.
- Maintenance: Regularly check for wear and reapply sealant when necessary.
Treat your timber planter box with care to enjoy it for many seasons to come.
Site Preparation and Installation
Before you install your timber planter box, it’s vital to select the right location and prepare the site to ensure a successful and enduring setup.
Location Selection
When selecting a location for your timber planter box, sunlight is key. Most plants require a significant amount of sunlight daily, so a spot that receives at least six hours of direct sunlight is ideal. Additionally, consider the proximity to water sources and shelter from harsh wind.
Preparing the Site
Once you’ve chosen the perfect spot, clear the area of debris and weeds. It’s important for the area to be level so your planter box can sit flat on the ground. You may need to add or remove soil to achieve a flat surface.
Installation Process
With the ground prepared, you can place your planter box in the designated area. If your planter box doesn’t have a bottom, laying down landscape fabric first can help to prevent weeds. For boxes with legs or a bottom, ensure there’s adequate drainage to prevent root rot. Secure the planter box in place and double-check that it’s level before filling it with quality potting mix.
Plant Selection and Care
When choosing plants for your timber planter box, it’s essential to pick species that will thrive in the contained environment and pay attention to the soil and fertiliser requirements.
Suitable Plant Types
For your timber planter box, you want to select plants that match the size and depth of the box, as well as the sunlight it receives. Herbs such as rosemary and thyme are ideal if your box is in a sunny spot. If you have a shaded area, consider ferns or hostas. Ensure the plants you choose are suitable for the current season and the climate zone in Australia where your garden resides.
Soil and Fertiliser
Use a high-quality potting mix that promotes good drainage and aeration, crucial for plant health in a planter box. Incorporate a slow-release fertiliser to provide your plants with nutrients over time. Remember to check the specific nutritional needs of the plants you’ve chosen and amend the soil accordingly. For example, flowering plants may benefit from a fertiliser high in potassium, while leafy greens may need more nitrogen.
