Spruce Bark Mulch, 60 Litre Bag, 5-35mm Ornamental Bark

Bark mulch is one of the simplest ways to cut weeding, hold moisture in the soil and give borders a tidy, finished look. This spruce ornamental bark mulch comes in 60 litre bags of natural spruce bark graded to 5–35mm pieces. Spread around shrubs, trees and perennials at around 75mm deep, it smothers weed seedlings, keeps soil cooler and damper in summer, and lasts for two years or more before it needs topping up. Gardeners, landscapers, local authorities, housing associations and grounds maintenance teams use it on domestic borders, commercial planting schemes, tree pits and play areas, and it is peat-free.

Why it works

Suppresses weeds

A 75mm layer of bark blocks light from reaching the soil surface, so most weed seeds cannot germinate. That means far less hand weeding and fewer chemical treatments across a season, which saves time on large landscaping schemes and in busy home gardens alike.

Holds moisture in the soil

Bark shades the soil and slows evaporation. Plants under mulch need less watering in dry spells, which is especially useful for newly planted shrubs and trees that are still establishing roots.

Long-lasting, 5–35mm grade

The bark is graded to 5–35mm pieces. That mix of sizes knits together into a stable layer that resists blowing about, while the larger pieces break down slowly. The supplier states it lasts two years or more before it needs topping up, so you are not re-mulching every spring.

Natural, peat-free finish

Spruce bark gives a warm brown, natural look that sets off green foliage and flowers. It is a peat-free product and gradually adds organic matter to the soil as it breaks down.

Where it's used

• Shrub and perennial borders in gardens
• Commercial and public landscaping beds
• Around newly planted trees and hedges
• Tree pits and roadside planting
• Paths through woodland-style gardens
• Low-maintenance planting on housing and business sites

Specifications

Choosing the right option

This listing is a single 60 litre bag. To work out how many bags you need, measure the area in square metres. At the recommended 75mm depth, one square metre needs 75 litres of bark, so each 60 litre bag covers roughly 0.8 square metres. Multiply your area by 1.25 to get the number of bags and round up.

For example, a border 5m long and 1m deep is 5 square metres and needs about seven bags. A 10 square metre bed needs about thirteen bags. If you are mulching over existing light mulch, a thinner top-up layer will need fewer bags.

Installation, use & care

Clear existing weeds, especially perennial roots, and water the soil well if it is dry. Spread the bark evenly to around 75mm deep, keeping it a few centimetres back from plant stems and tree trunks so they are not smothered. For the best weed control, lay a permeable weed membrane first and spread the bark over it. Rake the surface level occasionally and top up thin areas as the bark breaks down over time.

FAQ

How deep should I lay it?

Around 75mm. That depth gives good weed suppression and moisture retention.

How long will it last?

The supplier states two years or more before topping up is needed.

How much does one bag cover?

At 75mm deep, a 60 litre bag covers roughly 0.8 square metres.

Is it peat-free?

Yes. It is a natural spruce bark product with no peat.

Can I use it over weed membrane?

Yes. Laying a permeable membrane first and covering it with bark gives the strongest weed control.
