Popular in all sorts of garden designs, bark and wood chippings have many uses. In pots, borders and pathways, there are plenty of ways to incorporate bark in the garden.

They can…

• Suppress weeds
• Be found for sale at most garden retailers
• Look attractive
• Make beds and borders easier to maintain
• Be used in pots, tubs and even hanging baskets
• Provide a good mulch and help retain water for plants and shrubs
• Compost slowly, so they only need topping up occasionally

In the border

Bark and wood chippings provide a natural barrier against weeds. You need to lay them about 5cm deep, so check your measurements to make sure you buy enough material to cover the desired area.

Protect

A layer of chippings will also protect plant roots from frost damage in winter or scorching sun in summer.

Mulch

They make a great mulch, helping to retain moisture in the soil and a healthy environment for your precious plants. Make sure the material is classed as suitable for mulching and not fresh chippings, which can temporarily remove nitrogen from the soil.

In pots

Chippings come in different sizes. Smaller chippings are the perfect choice for pots and tubs. They suppress weeds and keep moisture levels up – meaning less watering during summer and periods of drought.  Make sure the chippings are not fresh or they will temporarily suck out nitrogen from the soil.

Compost

They will compost down, but it’s a slow process so you shouldn’t need to top up often.

This process also enriches and aerates the soil.  Bark chips also stimulate plant growth as mulched plants and trees grow faster than un-mulched!

On the path

Chippings are also an excellent sustainable, permeable alternative to more expensive, impermeable hard pathway materials like paving slabs; giving a different texture and look to the garden as well as being durable and low maintenance.

There is generally no need to lay unsustainable plastic membrane under the mulch if you add a layer of chippings at least 10cm deep. Just make sure to add some form of edging each side to keep the chippings in place. Simple wood edging works well and is cheap. An even cheaper option is to edge with fallen branches.

What to buy

You can buy bark and wood chippings at all good garden centres and plant nurseries. Reputable retailers will ensure the wood comes from a renewable source – this should be clearly labelled on the packaging. Look for FSC Certified (Forest Stewardship Council) which guarantees that the wood and bark is responsibly sourced.

Frequently Asked Questions

1 – What are the benefits of using bark or wood chippings in the garden?

Bark and wood chippings help suppress weeds, retain soil moisture, and protect plant roots from temperature extremes. They also add a natural, attractive finish to borders, pots, and pathways, while gradually improving soil structure as they break down.

2 – Are bark chippings good for pots and containers?

Definitely. Smaller-grade chippings are ideal for pots, tubs, and even hanging baskets. They help retain moisture, reduce watering needs, and prevent weeds from taking root—making summer care easier and more efficient.

3 – Can I use bark chippings on garden paths?

Yes, wood and bark chippings make a durable, low-cost, and permeable path surface. Lay them 10cm deep for best results and edge with simple wood or branches to keep them contained. There’s no need for plastic sheeting underneath if the layer is deep enough.

4 – Is bark mulch good for protecting plant roots?

Yes. In summer, it shields roots from scorching sun, and in winter, it insulates them against frost. This helps maintain a stable environment for healthy root growth year-round.

5 – Where can I buy bark or wood chippings for my garden?

You’ll find bark and wood chips at all good garden centres, nurseries, and DIY retailers. Look for bags labelled for mulching or decorative use, and double-check they’re from a renewable or FSC-certified source for peace of mind.
