Wooden Planters: Natural, Durable and Stylish

Wooden planters for gardens, patios and balconies

A wooden planter is a simple and attractive way to introduce more greenery into your outdoor space. Whether you want to create a colourful floral display, grow fresh herbs or showcase an ornamental shrub, wooden planter boxes offer a versatile planting solution.

With their natural appearance, wooden garden planters complement both traditional and contemporary outdoor settings. They look particularly attractive alongside timber fencing, garden furniture, paving and other natural materials.

At Intergard, you can choose from robust wooden planters in different shapes and sizes. Our pressure-treated softwood planters are made from FSC®-certified timber, supplied ready assembled and designed for outdoor use.

Which type of wooden planter should you choose?

The best wooden planter box for your garden depends on the space available, the plants you want to grow and the look you wish to achieve.

Rectangular wooden planters

Rectangular wooden planters are ideal for positioning alongside a fence, garden wall, pathway or patio edge. Their elongated shape makes it easy to combine several plants in one display.

Intergard offers rectangular wooden planters in lengths including 60, 80 and 120 cm. They can be used for colourful flowers, lavender, ornamental grasses or a mixture of suitable plants.

Square wooden planters

A square wooden planter works particularly well beside an entrance, on a patio or in a smaller garden. Its balanced shape makes it suitable for a single statement plant or a compact floral arrangement.

Our square designs include sizes of 40 × 40 and 50 × 50 cm.

Hexagonal wooden planters

For something a little different, a hexagonal wooden planter creates an eye-catching garden feature. Its distinctive shape adds interest to patios, pathways and planted areas.

Intergard offers hexagonal designs in sizes including 50 and 70 cm.

Wooden planter sizes – which is right for your space?

Small wooden planters are ideal for compact gardens and balconies, while large wooden planters provide additional growing space for more substantial planting arrangements.

Planter shape	Available sizes	Suggested use
Rectangular	60, 80 and 120 cm lengths	Patio borders, flowers and ornamental grasses
Square	40 × 40 and 50 × 50 cm	Entrances, balconies and individual plants
Hexagonal	50 and 70 cm	Decorative planting and garden features

Always check the full external and internal measurements before ordering. The internal depth and available compost volume are particularly important for healthy root development.

Pressure-treated wooden planters for outdoor use

Our sturdy pressure-treated wooden planters are made from softwood treated with a chromium-free wood preservative.

During pressure treatment, preservative is introduced into the timber to improve its resistance to certain causes of deterioration. The depth of penetration depends on the wood species and treatment process.

Pressure treatment helps make timber suitable for outdoor applications, but good drainage and sensible maintenance are still important.

The described softwood planters are also made from FSC®-certified timber, supporting responsible forest management.

Hardwood planters – a natural alternative

In addition to pressure-treated softwood, Intergard offers hardwood planters for customers looking for a different timber finish.

Hardwoods such as Bangkirai are valued for their density, strength and natural appearance. They can complement hardwood decking, garden fencing and contemporary patio designs.

Like other natural timber products, hardwood may change colour when exposed to sunlight and rain. Appropriate maintenance can help preserve its appearance.

Browse our hardwood planters to compare the available designs and specifications.

Why do wooden planters need a liner?

Many of Intergard's softwood wooden planter boxes are supplied with a water-permeable liner. This provides several practical benefits.

• Helps protect the timber: reduces direct contact between damp compost and the inside of the planter.
• Keeps compost in place: helps prevent soil from escaping through gaps between the boards.
• Allows drainage: a permeable liner allows excess water to pass through when the base provides a suitable outlet.
• Makes planting easier: creates a more contained area for filling with compost.

A completely waterproof liner without drainage can cause water to collect around the roots. Always ensure that excess water can escape from the planter.

How much compost do you need for a wooden planter?

The amount of compost required depends on the internal dimensions of the planter and how much space is occupied by existing root balls or other materials.

To calculate the approximate internal volume, use this formula:

Length × width × filling depth in centimetres ÷ 1,000 = volume in litres.

For example, a wooden planter with internal dimensions of 80 × 40 × 35 cm has a theoretical capacity of:

80 × 40 × 35 ÷ 1,000 = 112 litres.

The actual amount of compost needed may be lower if you leave space below the rim or add plants with established root balls.

How to fill a wooden planter correctly

Preparing your wooden garden planter properly helps create healthy growing conditions and reduces the risk of waterlogging.

1. Choose the position: consider sunlight, wind exposure and the needs of your plants.
2. Check drainage: make sure excess water can escape from the bottom.
3. Inspect the liner: use the supplied water-permeable lining according to the product instructions.
4. Add suitable compost: choose a growing medium appropriate for your plants.
5. Position the plants: allow enough room for growth and root development.
6. Water thoroughly: moisten the compost without leaving it permanently waterlogged.

A thick layer of gravel or clay pebbles is not a substitute for proper drainage. The planter should have a suitable way for excess water to escape.

What can you grow in a wooden planter?

Wooden flower planters can be used for a wide range of plants, provided the container offers sufficient growing space and the right conditions.

Flowers and perennials

Geraniums, petunias, pansies and other seasonal flowers can create colourful displays. Lavender and selected compact perennials can also work well in suitable planters.

Ornamental grasses and small shrubs

Ornamental grasses provide texture and movement, while compact shrubs can create a more structured display. Make sure the planter has enough depth and volume for the mature root system.

Herbs

Grow parsley, basil, chives and mint to create a convenient herb garden on your patio or balcony. Bear in mind that different herbs have different watering needs. Mint is often best grown separately because it spreads vigorously.

Strawberries and vegetables

Strawberries, lettuce, radishes and certain compact tomato varieties can also be grown in appropriately sized planters.

For edible crops: check that the treated timber and any liner are suitable for use near food-growing compost. Where necessary, use an appropriate barrier between the treated wood and the growing medium.

Wooden planters for balconies and patios

A wooden planter for a balcony is an excellent way to introduce flowers and greenery when outdoor space is limited.

Compact square and rectangular planters can brighten a balcony without taking up too much room. On a larger patio, several wooden planters can be arranged to define seating areas, create borders or add seasonal colour.

On balconies and raised terraces, always consider the total weight of the planter when filled with wet compost and plants. Check the load-bearing capacity of the surface and position the planter securely.

Explore our balcony planters for more options.

Wooden planters with trellis for climbing plants

A wooden planter with trellis combines a planting container with vertical support for climbing plants. It can be an attractive way to add greenery to a patio or create a natural-looking screen.

Depending on the planter and its construction, a suitable garden trellis may be incorporated into the design.

Climbing plants such as clematis, honeysuckle and annual nasturtiums can be considered, depending on the location, planter size and support structure.

Make sure any trellis is securely fitted. Tall structures and mature climbing plants can catch the wind, so the complete arrangement must be stable enough for the expected loads.

Wooden planters for growing vegetables

Wooden planters can also be used to create a small kitchen garden, allowing you to grow herbs, salad leaves and selected vegetables close to your home.

If you prefer a dedicated growing area, explore our vegetable garden boxes and square foot gardening products.

Choose a suitable growing medium, allow sufficient root space and ensure that the materials are appropriate for growing edible crops.

Can wooden planters stay outside all year?

Outdoor wooden planters designed for garden use can generally remain outside throughout the year, provided they are installed and maintained appropriately.

Pressure-treated timber offers improved resistance to certain forms of deterioration, but standing water and prolonged damp conditions should still be avoided.

During winter, some plants may need additional protection against frost, particularly when their roots are exposed to low temperatures in containers.

How to maintain wooden garden planters

Wood is a natural material that changes in appearance over time. Regular maintenance helps keep your timber planters in good condition.

• Remove leaves, dirt and accumulated debris.
• Check that drainage outlets remain clear.
• Avoid leaving the planter standing in water for long periods.
• Inspect timber boards and joints for damage.
• Check the condition of the internal liner.
• Apply an appropriate exterior wood treatment when required.

Natural weathering may cause the timber to develop a grey appearance. This does not necessarily mean the structure has lost its strength.

How long do wooden planters last?

The lifespan of a wooden planter box depends on the timber species, treatment, exposure to the weather, drainage and maintenance.

Pressure-treated softwood has been treated to improve its resistance to certain forms of decay. Some hardwood species are naturally durable, although their properties vary.

A planter with effective drainage and suitable maintenance will generally have more favourable conditions than one that remains permanently damp.

Gardening tip: create a layered spring bulb display

For a colourful display over several weeks, try layering spring bulbs in a large wooden planter. This technique is sometimes known as bulb lasagne planting.

Bulbs are planted at different depths according to their size and growing requirements, allowing different flowers to emerge throughout the season.

1. Prepare the planter: use a sufficiently deep container with effective drainage and suitable compost.
2. Bottom layer: plant larger bulbs at their recommended depth, such as selected tulips or daffodils.
3. Middle layer: add compost and position suitable smaller bulbs, such as certain hyacinths or daffodils.
4. Top layer: plant early-flowering bulbs such as crocuses or grape hyacinths.
5. Finish: cover with compost and water gently.

Follow the recommended planting depth and spacing for each bulb variety. Position bulbs in a staggered arrangement rather than directly on top of one another.

You can also add seasonal bedding plants, such as pansies, for colour before the bulbs flower.
